Review & Installation Video

Review & Install Video

Suburban Streets or Off-Road Adventures. Whatever your driving pleasure, the Teraflex 3" Sport S/T3 is a suspension kit that delivers dependable performance. The comprehensive set includes the front and rear 3" springs, an adjustable front trackbar, 6 sport flexarms and 4 of the popular SpeedBump bumpstops. Of course, installation hardware and instructions are also included.

Progressive Bumpstops. The truly progressive design of the included SpeedBump bumpstops reduce suspension-compressing impacts and the related harsh speed bump bottoming. This means you're less likely to risk bends in your axle housing and you're more likely to keep overall control of your 4-door Jeep Wrangler. Made with microcellular polyurethane technology, these bumpstops are not affected by temperature extremes.

Vibration-Damping Bushings. The factory-style flex arm bushings offer several benefits when it comes to driving comfort. They minimize vibration, road noise and general clunkiness while ensuring proper positioning to maximize articulation during travel. As a bonus, they are completely maintenance-free.

Bolt-On Installation. Designed as a straight forward and easy installation, this 3 inch Suspension System doesn't require any additional alignment or adjustments for taking it off the beaten path. While time consuming, this S/T3 Sport System is an 'install and drive' upgrade to get you back to enjoying your Wrangler on the street and trails.

Application. The Teraflex 3 in. Sport S/T3 Suspension without Shocks is an ideal upgrade for any 4-door 2007-2018 Jeep Wrangler JK.

This kit includes exhaust spacers right? It's not listed here but it's in the picture. It's also listed on teraflex's site for this same kit.

  • Yes the spacers are indeed included, what you see in the picture is exactly what this lift kit will be coming with.

I didn't notice any brake line extensions in this kit. Are they not needed for this lift or are the brake lines managed in some other way? Would it be better/easier to install if I ordered separate extensions along with the kit? Thanks

  • The Teraflex 3 in. Sport S/T3 Suspension w/o Shocks comes with brake line extension kits to assist with rerouting the brake lines.

Does this product require driveshaft replacement?

  • Any time you lift your Jeep over 2 inches, like with the Teraflex 3 in. Sport S/T3 Suspension, you run the risk of needed to replace the front driveshaft, rear driveshaft or both. You should not need to, but every Jeep reacts a little differently to being lifted.

    The ultimate daily driver and weekend warrior kit!

    I've had this lift and setup on 35inch tires for 6 months now and couldn't be happier. This kit handles great on the road/highways and is a beast on the trails. You can instantly feel the stability of the Jeep and have no worries of death wobble or that tipping feeling on or off the trail. Can't go wrong with Teraflex products!!

    Rides better than stock

    I purchased this kit because my Jeep is my daily driver and I didnt want to get a suspension system that would suck for on road use. I did at least 100 hours of research to find the perfect lift kit that would perform the beat for my needs; this is that kit. It includes everything needed to do a lift the right way without cheaping out with certain components. After installing this kit, I immediately noticed the difference over the stock suspension. This kit is much more firm and responsive than factory. Hitting speed bumps at 30 MPH are almost not even noticeable anymore. The Jeep no longer dips when making sharp turns and it also does not have the factory nose dive when slamming on the breaks. I almost like to hit bumps now because this kit handles them so well. I purchased Teraflex’s Falcon 3.3 shocks along with this kit because I read that the Fox Reservoir shocks that come with the other version of this kit ride to firm. With the Falcon 3.3’s, I’m able to adjust the dampening with the twist of a knob. I don’t notice a big difference between the most firm setting and the most soft setting, but I keep mine at the soft setting because my Jeeps can sway a little bit more than on the firm setting. I installed this kit with a buddy in about 14 hours. I used floor jacks, jack stands, almost every socket set I have, an electric impact tool, an electric drill, a Dremel, and an electric reciprocating saw. The front axle installation was the most difficult part to accomplish. The cutting of the pump stops took me about 2 hours to do. The next most time consuming thing was the exhaust spacer. Teraflex ‘s instal video says to use an electric chissel of just use a hand chissel...sure. U used a hand chissel and it didn’t do anything. I wound up using the dremel to cut the spot weld on the Y pipe clamp. Even using the dremel was difficult because there is no room to fit in there. The last thing that took a while was the rear bump stop installation. I had to place the cup on the factory bump stop and place a wood block between the cup and the axle and jack up the axle to compress the cup. After compressing the cup a little bit, I lowered the axle and slammed the cup for a few minutes with a sledge hammer. Other than that, the rear installation was easy. I am currently running 33’s on my JkU and plan on going to 37’s before Christmas. I actually think that this kit gave me more than 3 inches even though I have steel bumpers in the front and the back with a 60 pound winch up front. Before the lift, I could look over the roof of my Jeep even with the 33’s. Now, after the lift, The roof of my Jeep is about 2 inches over my head and I am 6 foot 3. I love this kit, and if I had to pick a kit for another Jeep, it would be this kit again. Definitely worth the price in my opinion. You won’t regret bying this kit.

    Great and expedient service

    Great lift, everything you could possibly need for wanting to make your daily driver a little more fun. You can ignore the sticker teraflex puts on the box about needing wheel spacers with stock wheels and tires

    GREAT

    This kit is not that hard to install. I purchased Superlift adjustable upper control arms to help with caster angle and driveshaft angle. I put a little negative caster on the front to help with driveshaft clearance till new one is purchased. Went with Bilstein 5100 shocks. Drives and handles great. Does not squat in the rear when you take off and very little sway in turns. Only been off road once on small trails but performed great. Wife approved! Its her daily driver.

    Extremely complete kit

    I did the lift mostly myself and took about 7 hours in total to do. however I would say I did have access to a lift and all the tools and air tools one would need to do it. Some suggestions I would have in doing this kit is get the best penetrating oil you can buy or do the automatic transmission in acetone mix at 50/50 and some crucial bolts that need to soak at least a day before you attempt to start your lift. Ones I can tell you must get it are your exhaust bolts. I drive over donner summit every day for work so sand and salts are an issue for me. Although most bolts other then the exhaust don't require it. Some tools I would highly recommend for speeding this install up are a battery impact with socket adapter breaker bar and an extra buddy to help. An 18mm ratcheting wrench will be a life saver and also a 5/8th or 16mm ratcheting wrench for the top of the shock. Trust me your wrists will thank you for it. Mostly just fallow the instructions or the teraflex video install and don't jump ahead. I was doing all the suspension work while a buddy worked exclusively on my rusted exhaust. Helped us stay out of each other's way. Everything goes together pretty quickly and make sure not to over torque your bolts. All specs can be found online if you need them. Now for the ride quality. I bought this kit because I am not a Baja racer and don't need the piggy back shocks. Look cool but you don't need them for a DD or a trail and crawlers. I did buy fox podium 2.0 non reservoir shocks for mine. There is a huge difference over stock to what it is now. Before I had hard jolts going over bumps or pot holes on the highway and now it's smooth and supple. Being taller you'd think you would get body roll but no it handles well and really is worth every penny. I am running 35x12.50r15's yes that's right a 15 inch rim and the Jeep seems to like it helps cushion the road and the fox shocks really make it something special. Not having metal bumpers I did have a large gain in lift with tire and lift combined. bottom of rear fender before was 35 inches to the lip to ground and now I'm sitting at 43.5 lip to ground. I'm sure with metal bumpers and winch and so forth it would lower to 41.5 ish. I'm 5'9" and my Jeep towers 6-8inches above my head to the roof line. I live only an hour from the rubicon so I'll be trail testing this kit quite soon. As far as I can see the added benefit of a maintenance free kit is I don't have extra things to worry about. One thing I would add when you do your lift now or down the road is adjustable front upper control arms to fine tune your front. Overall in love with how it has turned out.
