      Video Review & Installation

      Hey, what's up, guys? I'm Ryan from ExtremeTerrain and today I'm here with the Teraflex 2.5 inch Lift Kit with 9550 Shocks fitting your 2007 to 2018 two-door JK. This is gonna be for the jeep owner that is looking for a very reliable kit that's going to handle all that abuse that they can throw at it. This is for those of you that are looking to spend a little extra money on a quality kit that's really gonna hold up well over time. This kit is gonna give you great on and off-road driving and performance and it's gonna give you that additional ground clearance that you're looking for, allowing you to fit larger tires up to a 35-inch tire, giving you an edge on those trails.Now as far as lift kits go, this is a pretty basic lift kit. However, Teraflex gives you all of the necessities needed to get your Jeep lifted back on the road and ready for those trails. Now, this kit is a direct bone on. However, there is no drilling or modification required. However, we are dealing with suspension so I recommend professional installation. Now, as far as lift kits go, this one is reasonably priced considering you're getting very high-quality components. At just around $750 I think this is a great option to go with. You're getting a kit that is made in the U.S.A. and is engineered and tuned by Teraflex.Now Teraflex requires the use of wheel spacers if they're using those factory wheels. If you're using aftermarket, you want a backspacing of at least 4.5 inches. Now, wheel spacers are not included in the kit. You can find many options on our website. Now, as far as installation goes I am gonna give this two out of three wrenches on the difficulty meter since we are dealing with suspension. However, expect this to take you about a half a day and you can get all of this done with basic hand tools.Tools we use for this install: a hammer, a dead blow hammer, adjustable wrench, channel locks, razor blade, flat-head screwdriver, prying tool, this applied nut-holding tool, standard and metric socket set, a pry bar, 3/8ths drive ratchet, various extensions for that ratchet, standard and metric wrench set, a long extension, half-inch drive impact, ratchet strap, 3/8ths drive impact, and some lubricant.So there are multiple ways that you can do this. You can do this on the ground with jack stands or you can do it on the lift just like we're doing it. We have the Jeep out. We already took our wheels and tires off. First thing we're gonna do is take the splash shield off. So we're gonna use a flat-head screwdriver to take the pushpins out. So we're just gonna pry up on this center section here, pull that middle out and then we can push the whole thing out. We're gonna have four of them in the front here and then we're gonna have two back here.After we get that last pushpin out, we could just pull the shield off. So the next thing we're gonna do is we're gonna support our axle with pole jacks, maybe doing this on the ground if you want to use jack stands. So we're gonna do one on each side, making sure that we're not gonna block anything that we need to take out. So at the end of the track bar where it meets the axle, we're gonna take bolt out. There is a flag nut on the backside, we're gonna use a 21-millimeter socket to remove that bolt.So the next we're gonna do is remove our sway bar end links. So we are gonna disconnect these from the top and bottom because we're getting rid of them, we'll switch them out for other ones. So we're gonna start with this bottom bolt. We're gonna need an 18-millimeter socket and an 18-millimeter wrench. So for these guys up top we're gonna use an 18-millimeter wrench for the nut. You can either use an Allen Key to hold that still or you can use a 19 on the backside here. So I'm gonna use a 19 or an 18. Now, we're gonna do the same thing for the other side. Bottom one is a little tricky to get to but you can get a wrench on there, so I'm gonna have to use a socket on our wrench because we can't get an impact there.So the next thing we're gonna do is take our shocks out. We're gonna start with this bottom bolt on here. We're gonna use an 18-millimeter socket and a wrench to get that out. So next, we're gonna do the top. We're gonna use the 16-millimeter wrench to hold it here and we're gonna use a 16-millimeter wrench up top as well. This is gonna keep the shock from spinning while we take the nut off. So at this point in time we are just about ready to lower the axle. The next thing we have to do is free up our brake line and our ABS. So right here on the axle we're gonna have this bracket. We're gonna use a 10-millimeter socket to take that bolt out.So at this point in time we are ready to lower the axle down, that way we can remove those factory springs. Now if it doesn't drop enough you may want to remove your drag link. And also there is a differential vent hose you need to pull off. So we're gonna lower this axle down, pull those springs out. So we finally got that front completely disassembled. We are just about ready to install our brand new kit from Teraflex. But before we do that, I just want to take a moment to tell you a little bit about what this kit consists of, what it's gonna do for your Jeep, and how it compares to your stock setup.Now, the first thing we want to talk about is the coil springs. The coil springs are going to give you the height. So why do we want to lift our vehicles? We want additional ground clearance and we want to fit larger tires. That's gonna give us even more ground clearance. We're gonna be able to articulate the suspension a lot better than stock. That's gonna allow us to get over rather large obstacles on the trails. The coil springs are a lot thicker coiled than your stock ones. This is gonna add provided support and it's gonna allow you to add aftermarket bumpers, winches. It's gonna hold all that stuff up. Now the coils are wound a little tighter which is just gonna add to that strength and that's mainly what's gonna give you the lift.Now, the next thing I want to talk about is the shocks. Now, these shocks are Teraflex's 9550 shocks and they are vehicle-specific shocks. They're specifically tuned to work with Teraflex's springs so this whole kit is gonna work really good together. It's gonna ride really nice. Now, like I said, these are nitrogen-filled and your stock shocks are hydraulic. Hydraulic stocks tend to ride a little bit smoother than the nitrogen shocks but these 9550s are a really nice shock. These are valve-tuned and engineered for peak off-road performance while maintaining that on-road drivability. These are a twin tube design. Now, this has an oversized outer tube that's gonna protect that inner tube so if you happen to dent these on the trails, it's really not gonna affect function too much.Another nice thing about these is they have an internal stop limiter. So this travel limiter is gonna keep you from over-compressing them on the trail and damaging the functionality of the shock. They have an oil block seal which is gonna keep all of that in there and it has a hardened shaft that is triple chrome plated and that's gonna keep any dust and debris that it builds up on that from ruining that seal and letting all that gas and oil leak out.Now, they come with Knights' heavy duty bushing so all that's gonna last you a long time. Now, of course, we are lifting the Jeep. We're pulling those axles a little bit to the side with the stock track bars so we get a track bar relocation bracket for the rear. That's gonna pick that track bar up just a little bit and increase that roll center somewhat back to factory specs. Now, of course, we're running larger tires because we have more tire to fender clearance. So, of course, we don't want them to run into the fenders when we're articulating the suspension. So we're getting brand new bump stops for the front rear. It's gonna prevent us from doing that. This whole kit is gonna lift your Jeep up. It's gonna allow you to fit up to a 35-inch tire.Now, another nice thing is we get brand new sway bar links. We're getting brand new sway bar links for the rear because we're taking the rear ones, we're putting them on the front. However, that is going to flatten out those sway bars and it's gonna give us a really nice ride on the road. Now, with all that being said, let's show you how this gets installed and what it looks like on the jeep.So the next thing we have to do is take this bump stop out. They are pretty stuck in there so you can spray them with some lubricant. And after that, we're just gonna wiggle this back and forth and we can get that out of there. So if you have a lot of trouble getting these out, what you can do is take a flat-head screwdriver and just jam it up in there, pry that out of there. So next, we're gonna install our new bump stop extension from Teraflex. You want to take some grease to just grease this little end up then we're gonna wind up putting that bump stop up in here so you want to grease the bump stop as well. So we're gonna do that and install it in there.All right, so the way we're going to do this is we're actually gonna use the axle to push this up and in. So get it in there as far as we can. Now we're gonna set this up there, we're gonna use the axle to actually push this up in. So with our bump stops in we're ready to install our new springs. Now, at the bottom of the coil spring you're gonna have a stop on this bracket. You want to make sure that you line that little pigtail up with that. Next, we're gonna reinstall our brake line bracket. We need to do this before we put our shock in because once we get our shock in we're not gonna be able to fit it back there. Once we have that in we're gonna take our 10-millimeter socket, we're gonna tighten that bolt up.So the next thing we're gonna do is install our brand new shocks. Now you're gonna get a bag of hardware. This is gonna have cup washers, bushings, and nuts. So we're gonna place a cup washer facing up and we're gonna place a bushing on that. And that's gonna go up to the top and then we're gonna do the same thing, bushing, cup washer, and then a nut. So I'll show you how to do that right now.After you get that installed, we're gonna take a 14-millimeter wrench. We're gonna tighten that nut up. So we're gonna compress these bushings in good amount and we're gonna move on to the bottom of the shock. So for the bottom of the shock we're gonna reuse that factory bolt and nut. So you want to raise your axle until both of these holes line up and we're gonna reinstall that and use a series of 18-millimeters to tighten it up. Then you can do the same thing for the other side.So we have a few more things to do on the front. We have to reconnect our track bar. We also need to put our sway bar links in but we are pulling those from the rear. So what we're gonna do right now is we're gonna put our track bar bolt back in. So there's two ways that you can do this. You can do it up in the air like we're gonna do it with a ratchet strap, or you can wait until the end, put your wheels and tires on, set her on the ground, use her steering wheel to just shift the body over that's gonna align that hole over. So I'm gonna show you how to do it with the ratchet strap.So we're gonna go over here. We're gonna hook on to a good spot to pull from and then we're gonna come back over here and hook onto another spot. So what we're trying to do with this is just hook on to the axle, hook on to the frame. You want to shift the axle this way so we can get this hole to line up. So we've got it in place so we're gonna start cranking down on this and you'll see that it's gonna shift it over. That's gonna get us pretty close and that way we can reinstall that bolt and that flag nut. I'm gonna put our flag nut on the back. Let me get that started. And we'll take our 21-millimeter socket and we'll tighten that up. After that, we can release our ratchet strap.So like I said, the last thing to do in the front is to put those new sway bar links on. So we came back here to the rear real quick just to take these off so we can finish up the front. So just like the front ones, you're gonna need an 18-millimeter wrench and a socket to take out those lower bolts. So we're gonna start with that first. So for the top, we're gonna use an 18-millimeter socket for the nut and we're gonna use a 19-millimeter wrench for the stud. So we're gonna go back up to the front. We're gonna install these new links. So we're gonna start with the top, the top has the stud side that's gonna poke through from the outside to the inside and we're gonna reinstall that nut. On the bottom, we're gonna pass our bolt through the outside that's gonna get through the link and then we're gonna put the nut on the inside. So we're gonna go ahead and tighten them up.So just like front, we are gonna start by supporting this axle with pole jacks, that way we can take this track bar completely out of the vehicle. So let's start here at the axle side. We're gonna use a 21-millimeter socket to get this bolt out. So over here at the frame side we're gonna use a 21-millimeter socket. On the other side you can use a wrench or you can use an adjustable. Now, you want to be careful when you loosen this up because the track bar is stuck in position but as soon as you loosen it up it's gonna swing down. So we're just gonna let that swing down and we'll get this the rest of the way out. Nut off. Get a hand on the track bar, get that bolt all the way out.So next, we're gonna go above our axle to the bottom of our tub. We're gonna take these two 10-millimeter nuts off. It's gonna give us a little slack in our e-brake cables so we can lower our axle down when we're ready for it. Next, we're gonna free up some slack in our ABS line. So just use any kind of pry tool, flat-head screwdriver just to pry that up. It's gonna give us a little extra room when we move this down.So the next thing, on the same side, we're gonna remove our brake line here. So you're gonna use a 10-millimeter socket for this bolt then you can do both of those steps on the other side. So the next thing we're gonna take out is the shocks. We're gonna start with the bottom. We're gonna use an 18-millimeter socket, 18-millimeter wrench. So next, we're gonna do the top of the shock. We're gonna use a 16-millimeter socket on a long extension. We're gonna get that up. Next thing we're gonna do is lower our axle down, that way we can get these springs out. Pull these springs out. We're gonna keep this factory isolator so we're just gonna lay it right there for now.So first, what we're gonna do on the back is install our bump stops. Now, these bumps tops are gonna have a little bit of a shelf. They have two holes in the bottom. This shelf is gonna face towards the front of the vehicle. You can have a packet of hardware. These are relatively long bolts. There's four of them, a ton of washers and bolts. What we're gonna do is put a washer on each one of these bolts. They're gonna drop down through these holes through this bracket on here and then we're gonna put a nut and a washer on the bottom. I'm gonna show you how to do that right now.Next, we're gonna take two half-inch wrenches, we're gonna tighten these up. So the next thing we're gonna do is install our track bar bracket. Now, this track bar bracket utilizes this bolt on the lower control arm so we need to take this bolt out. We're gonna use a 21-millimeter socket and a 21-millimeter wrench if you have one, or an adjustable. So we're gonna do that right now. So we're gonna take our bracket. This is going to straddle our factory bracket. So we're gonna place this over the top of that then we're gonna reinstall this bolt through there. Now the control arm probably sprung up in the air a little bit so you need to pull that back down. We can get that bolt back through, reinstall that factory nut. And we're gonna leave that loose for right now. We're gonna get all these other bolts in that will tighten everything up.So now we have this on, the next thing we're gonna do is install our new bolt that we get through here. So you're gonna have this very rather large thick sleeve. We're gonna have a brand new bolt, course threaded, two washers, then we're gonna have a nut. So what we're gonna do is put a flat washer on this bolt. The sleeve actually is gonna go up in here. So we're gonna place that sleeve up through there, lining that hole up, and install this bolt through there. Then on the backside it's gonna get a flat washer, then it's gonna get that nut. And last but not least, we're gonna install our U-bolts. We're gonna have this large U-bolt they provide us with. It's gonna go around the axle through this bracket. We're gonna put large flat washers on there then we're gonna install the two fine threaded nuts that they provide us with.After that, we're gonna go around there and tighten everything up. First thing we're gonna do is tighten our lower control arm bolt. Next, we're gonna tighten this bolt here through our bracket. We're gonna use a 19-millimeter wrench on the backside, 19-millimeter socket on the front side, tighten that thing up. Then, lastly, we're gonna tighten up the U-bolt, that's the same 19-millimeter socket we're gonna use. We're gonna try to make these as even as possible. So at this point in time, we are ready to install our springs. You want to lower that axle down just enough, test fit these and make sure that they go in. We're gonna reuse that factory isolator. So what we're gonna do is stick that on top, the bigger end is gonna go at the top so we're gonna shove that spring up in there and then get it to sit on this coil seat. After that we're gonna raise our axle up just a little bit on this side to keep it in place because we have a retainer that we need to install down here.So you're gonna get a retainer kit with your lift kit. You're gonna have this large retaining flat washer. This is gonna go over the top of this mount and you're gonna have a bolt. That bolt is gonna drop down through. Then for the underneath, you were going to have this special tool. Now, this special tool, we need to reach out through the other side of this mount. We're actually gonna place this flange nut in there that's gonna allow us to stick that up in through that mount and then screw it into that bolt. So we're gonna have a lock washer. We're gonna place the lock washer ever so gently on top of this nut then we're gonna go up into there and try to get this screwed into that bolt.It's gonna be a little tricky. It might take you a few tries if you're an amateur. Now, we're gonna use a 9/16ths wrench to tighten up this bolt. Now you can do the same thing for the other side. So there's a lot of different ways you can put this thing back together. Next thing we're gonna so is the sway bar end links. The reason I'm gonna do this is because this bottom bolt is behind the shock. It gets a little tough to get through one of the shocks in there. So we're gonna install our brand new links. We're gonna reuse that factory bolt for the bottom.So as we get that back together, we're gonna use the 18-millimeter socket and wrench to tighten the bottom up. Then we're gonna use a 19-millimeter socket for the top. So after that, we're gonna install our brand new shocks. We're gonna reuse all that factory hardware. We're gonna start with the top because it's a little tricky to get in. What I normally like to do is get the outside bolt started. It's usually a lot easier to get that outside one started. Then we get this looped at one side on there, get the inside one started.After that, we're gonna take our 16-millimeter socket on an extension and we're gonna tighten it up. Once you get the top in, we're gonna raise the axle up some so we can line these holes up and we're gonna reinstall that factory bolt. We're gonna take our 18-millimeter wrench and socket and tighten that up. So we need to reconnect our vent hose. So we're gonna get a little bit more slack out of this. We'll actually gonna take it and put it on the other side of this frame room. So that's gonna give us a little more length and then we can just slide that back onto that.Then we are gonna reinstall our e-brake cables. So we're gonna slide that back up to there, reinstall those nuts and then we'll tighten them up with a 10-millimeter socket. We're gonna take our brake line drop bracket. These have an offset. We're gonna face that inward so we're gonna install this up in there. We're gonna put that factory bolt back in. After we get that factory bolt in, we can tighten that up. So in that same bracket kit, we're gonna have a bolt. We're gonna place a flat washer on that. We're gonna bring that down. We're gonna put that bolt through there. Then on the back side, it's gonna get a flat washer and a nut.Then we're gonna take an 11-millimeter socket and a wrench, we're gonna tighten that up. And you want to make sure that these brake lines aren't gonna hit anything so if you got to bend them away so that they don't rub on the frame, just give them a little bit of a clearance. Then next we're gonna reinstall our track bar. So we're gonna start with that frame side. We're just gonna reinstall that factory bolt. So before we tighten anything up we're gonna come over the axle side. We're gonna get this down. So we're gonna install this one in the bottom hole. Once you get that hole lined up, we're gonna reinstall that factory bolt. So after you get that bolt all the way through, we're gonna put that flag nut back on the backside then we're gonna tighten it up. We're gonna take that same 21-millimeter wrench and socket and tighten this other end up.So now you have this whole kit installed, you want to throw those wheels and tires back on and torque them down to factory specs. The steering wheel is gonna be slightly off so you can adjust the drive link yourself but you need to get an alignment so you can have them do that for you. However, that's gonna wrap up my review and install. For more videos like this, check us out at
