Review & Installation Video

Review & Install Video

I'm Ryan from, and this is my review and installation of the Synergy Heavy Duty Chromoly Tie Rod, fitting all 2007 and up JKs. Today we're gonna talk through the installation of this tie rod, which is a very simple one out of three wrench installation, because this is designed to bolt directly in place of your factory tie rod. We're also gonna talk about the construction and a few of the other features. This tie rod is gonna be for those of you who have big tires on your Jeep and like to wheel it and are concerned that you may bend your factory tie rod. The tie rod is in a location where it hangs sort of low, so you could certainly get it hung up on a rock, which would cause a damage, or even if you don't hit the tie rod directly on a rock, if you get a tire jammed in a spot, it could certainly bend the tie rod as well. So, upgrading to a much stronger tie rod like this is good insurance if you haven't damaged your factory one, and this makes a great replacement if you have, to make sure that you're not going to have the same problem again. Synergy makes really high quality products, so this is going to be a little bit more expensive than some of the other tie rods on the market, but in my opinion it's well worth it for the built quality. This tie rod is made from inch and three eighths 4130 chromoly, so you know it's going to be really, really strong. It's also heat treated for additional strength and powder coated so it will have a rusting corrosion free finish on it. This is fully adjustable and has bends very similar to your factory tie rod, so it'll sit right in place of that factory piece. This is double adjustable, so you can very easily set the tow of your Jeep while this is installed on your Wrangler without the need to keep popping the tie rod ends out of the steering knuckles. Now, again, this is designed to bolt directly in place of your factory tie rod. However, if you have the reed high steering knuckles, you can also use this part without any sort of modification. You can get these tie rods from Synergy in the future if you were to wear them out, because we all know having big tires can be hard on suspension and steering components. Now, because this does have some larger tie rod ends on it, Synergy recommends that you have a maximum of four and three quarter inches of back spacing. They really recommend that you're closer to four and a half inches. Now, that shouldn't be a big deal for a lot of you guys if you're running 33s or 35 by 1250 tires. Chances are you have around that four and three quarter inch back spacing number. However, if you are running a factory wheel, you may have an issue. The wheel spacer will also help push the wheel out away from the center line of the vehicle enough to get this fitted. Like I said before, this is a very simple one out of three wrench installation. All you need to do is first remove your factory tie rod, and you'll do that by removing the cotter pins and castle nuts then removing the tie rod ends from the steering knuckles themselves. Now, this is an area where a lot of people will have some trouble. You'll start hitting the top of the tie rod end with a hammer, which will just mushroom it and make it even more difficult to get out eventually. These are a taper fits, so there is a right way and a wrong way to remove these from your steering knuckles. There should be a flat spot on the casting of the steering knuckles that you are going to wanna hit with a big, heavy hammer at least once. Now, where you're actually hitting is perpendicular to the tie rod and threaded rod itself. You're not coming down on it. You're actually hitting it from the side. And that should create the tie rod making it a lot easier to remove. There are also some pullers that you could use to remove that factory tie rod end. If you're not reusing that, it's not a big deal if you rip one of the tie rod end boots. However, if you have your brand new tie rod installed and you need to remove it for any reason, you're not going to wanna use a puller and take a chance of damaging the boot. Once you have your old tie rod out of the way, you'll simply bolt the new one in its place, and then you can take some measurements to set the tow of your Jeep. Now, there are a few different ways to do this. My preferred method is to take a big pen, jack up the front of the Jeep so that you can spin the tire very easily, and hold the pen in the stationary location against the tire while you spin it. That will make a line all the way around the tire. Do that on both the driver and passenger side front tires. Then it's very easy to take a measurement on the backside of the tire compared to the measurement on the front side of the tire, and you can set your tow very, very easily. As we said before, you can install these tie rod ends in your steering knuckles and then make your adjustment because this is a double adjustable. The whole installation for this shouldn't take you more than a half hour, but you may have a little bit more time in adjusting depending on how exact you wanna get your tow dialed in. And you won't need any specialty tools to get this done, just some traditional hand tools, but having a big, heavy hammer will certainly make getting your old tie rod removed a little bit easier. Synergy is known for making high quality suspension and steering components, and this is no different. Sometimes with that quality comes a little bit of a higher price tag, and that is the case with this. However, in my opinion it's worth it. You don't wanna be on the trail when your factory tie rod becomes a taco, and you have to drive off completely towed in. So, I would definitely recommend spending a little bit more money going with this version of the tie rod, something that you know is gonna hold up really, really well, versus saving a couple of dollars and not being confident in your new steering components. So, if you have big tires on your Jeep and you like to wheel, chances are beefing up your steering components is on your list of mods, and if you're looking at a really strong tie rod that you know is not going to bend or give you any trouble, this is a great option. I also like the fact this is double adjustable, so it makes installation and adjustment very, very simple. So that's my review of the Synergy Heavy Duty Chromoly Tie Rod, fitting all 2007 and up JKs, that you can find right here at

Design and Construction. The Synergy heavy-duty tie rod is bent similar to the factory bar in order to clear sway bar mounts. Made from 1-3/8" 4130 chromoly and heat-treated to offer maximum strength, this rod is completed with an abrasive-resistant coating that provides corrosion resistance for the most durability on and off road. This kit comes complete with two heavy duty tie rod ends which feature a fully greasable sintered metal on metal bushing design for the highest wear resistance.

Advantages. Synergy boasts this is the strongest JK tie rod on today's market, sure to out perform your stock set up. You'll find this tie rod easily adjusts without removal, giving you a step up for future and past modifications to your Jeep. For the best clearance pair this bar with aftermarket wheels with a 4.5 inch backspacing on your wheels.

Installation. This system has a simple bolt-on feature for quick and trouble-free installation with the use of basic hand tools. No extra modification to your vehicle or special tools are required; however if you have stock wheels, you will need to invest in wheel spacers.

Application. The Synergy heavy duty chromoly tie rod is designed for 2007-2018 Jeep Wrangler JK models.

Will I need wheel spacers if I am running 275/55/18's?

  • Fitment with the Synergy Heavy Duty Chromoly Tie Rod and your 275/55/18s would depend on the backspacing of your wheels. It is suggested that you pair this bar with aftermarket wheels with a 4.5 inch backspacing on your wheels. If your wheels do not have 4.5" backspacing you will need a wheel spacer that pushes your wheels out atleast that far.

Will this work with the Mammoth 8 Steel Black 17" wheel? I think those are 3.75 backspacing.

  • Yes, the 4.5 inch backspacing is the limit, but anything under that will have the wheel sit out even further than if it was 4.5 inch backspacing, which will indeed allow for proper clearance and then some.

    Good product, but it doesn't exactly adjust from both ends once installed. You still have to drop the Passenger side tie rod end to make any adjustments for that side. Still happy with my purchase.

    Quick and simple install

    First off it is heavy duty, has massive 1 ton ends, and installation is a breeze with tires removed. Would have been easier if it came with the steering stabilizer mount, that being said save time and order an aftermarket stabilizer mount. Adjustability is fantastic and everything is built well. Now looking at other synergy replacement parts.

    I recently wheeled at PC and finally was able to test the tie rod. I'm still on stocker tires so hardly any traction but my front tires slipped off a rock and landed on the tie rod. There was a very loud bang, so I thought I broke something. Got out and looked, the tie rod was supporting the passenger side weight of the jeep. Thinking I just ruined my $400 tie rod, I angrily pulled out of the spot and took a tape measure to the wheels to check toe. To my shock the toe was still perfect. Best of all I barely scratched the powder coat. Which by the way if you have rubicon express lift, the synergy grey powder coat matches the rubicon express powder coat almost perfectly. In direct light you can the synergy is a couple shades darker but there shouldnt be sunlight under you jeep anyway. If your contemplating getting this tie rod because of the price, just do it. This thing is worth every penny.

    Not what I expected

    Just like the drag link, grease boots will not stay in place. They need a better retention system than the coil springs to secure them. Lots of flop in the joints.

    Freaky fast

    A fast and easy install. I was able to get this in so fast I though I had done something wrong. Only suggestion I would have to Synergy is to give a suggestion on how many threads to leave exposed on the TREs to start with. Otherwise everything was great, just what is looked for in an upgrade done by a newbie.
