TeraFlex 1753418 JK/JKU HD Forged Adjustable Front Track Bar (0-6” Lift)

This thing is a monster! I have spent more time underneath of Jeeps than I care to admit, so you can take my word for it. This is one of the best aftermarket products I've seen for a Jeep, period. It is made the same way that the stock bar is, except it is way bigger and has an adjustment sleeve. This is the way Jeep should do it at the factory! I bought this because my stock bar was flexing and I was getting "death wobble," which if you don't know is a resonating oscillation of the front wheels that makes the Jeep feel like it is coming apart. I tracked down the problem to a combination of a flexing track bar, and a worn drag link end. I ordered this to address the track bar and I ordered a drag link from another site. When I took my stock track bar off I found that the bushing on one end was worn out. After installing this and the new drag link, my Jeep handles better than new. I couldn't be happier! Some details: The Teraflex bar is nearly twice as thick as the stock bar and it has thicker, heavier bushings. The bushings are a press in standard type bushing but they look pretty tough compared to the stock ones. Teraflex does sell replacements for these if you ever need one. The adjustment sleeve is not just some flimsy piece of metal like you would see on some steering setups, it is a heavy, thick walled piece of pipe that is split down one side. The locking collars are also very heavy. I have no fears of this ever failing or coming loose. Unlike other track bars, you can adjust this one without having to remove one end, which is nice. Probably my favorite thing about this bar compared to other aftermarket versions is that it is a forged solid piece instead of tubing, which allows them to be curved around the diff, just like the stock bar. The ones made from tubing have clearance issues around the differential housing. Now I need one for the back because the front is so tight that the back feels loose now.

This is my first ever terraflex product and I have to say I’m very impressed. The reason I went with this one is because you Mount it and adjust it super easily turning it with your hand. No need to use a crescent wrench to adjust and unmount it like the others. Took me about 15-20 minutes to install and was able to get my front axle centered. Don’t forget to readjust your steering wheel after using the drag link! It makes your ABS turn on if you don’t realign your steering wheel because it thinks you are sliding.

This trackbar is a beast, makes the factory one look like a pencil necked wimp! It has larger than factory ID bushings. Factory trackbar uses 14mm bushings and bolts. TERAFLEX Monster HD trackbar uses 9/16" ID bushings. As you can see I beefed up my factory trackbar mounts with after market braces as well. The one on the axle end still has to be welded on. The trackbar will work with both the JKS axle brace (and others) and the SYNERGY MFG. frame brace. Buy the 9/16" bolt kit sold on Amazon as well. You may need to ream the factory mount holes if they aren't wallowed out, (most are when you remove the factory trackbar). 14mm holes to 9/16" is about .045" lager we are only talking thousandths of an inch here. I was lucky and already had a 9/16" reamer, an old, and heavily used one, that did the job very nicely. My 9/16" NFT bolt is longer than a factory bolt as well since I added the SYNERGY frame brace. PROS: If you ever would need to replace the rubber bushings, TERAFLEX sells them separately as well, they will need to be pressed or burned out, and then the new ones pressed in. Adjustable from factory to 6" lift! HD adjuster sleeve and hardware. Don't be afraid to crank down on the lock bolts when finally adjusted. NicE coat of powder coating. Zinc plated bolts and nuts. Forged steel HD construction Cleavite bushings Installation video on web site. Great customer support from TERAFLEX! CONS: Not cheap, but your getting what you pay for, and competitively priced against other HD adjustable trackbars. It would be nice if TERAFLEX included the 9/16" oversized bolts.

This is a must have if you plan on lifting your jeep. I added 2.5 inches of lift with 35's. The stock track bar could handle it but with much stress. You could actually hear the stock track bar stress under turns. Driving high speed (60 MPH) and above was harsh and a white-nuckle event as well. This teraflex track bar is a proper bar that erased all my concerns and issues. This is very sturdy and handles my turns and speeds very well. I hear no stress or binding with this beefy track bar. I like teraflex. I have their springs and faclcon shocks as well. You cannot go wrong. I installed this myself and was able to center my front axel with a few adjustments. This is my first review ever on amazon, so consider that well.

Nothing but good things to say about this company and their products, specifically the trackbar is high quality, about three times heavier than the stock trackbar, and waaaay stronger obviously. Teraflex has EXCELLENT customer service so you can buy this with no worry of not having someone to call in case of issues. This works on STOCK JK's with 0 lift up to 6" lift. Fix your death wobble/shimmies NOW! Dont wait until its too late and cause hundreds/thousands more in damage. Instructions are straight forward, no power tools required, just a jack, jackstands, torque wrench, and sockets. Make SURE you torque it on ground, not while its lifted.

Fit perfect and adjusted perfect

Great product, way better than stock. Solved my death wobble so far as I can tell. I've only driven it 20 miles since installing but bumps that normally cause my Jeep to have a seizure did not phase it. Side note though, if you have a factory RHD you will need to take the pieces apart and cut the threaded ends about 3/4" so that it will fit and adjust. I'd recommend going to a machine shop to do this. It's solid! The RHD track bar is about 1/2" shorter than regular. Other than that, easy install and made my Jeep drive insanely better.

Purchased a used JKU (my first Jeep) with the plan to keep it stock with the exceptions of addressing known JKU issues and beefing it up for light off-road use. After researching, decided Teraflex provided the best bang for the buck. I ordered the front and rear Teraflex track bars. I was impressed with the weight of the track bars, particularly after removing the stock track bars and comparing side by side. The Teraflex bars are substantially heavier. Installation for both bars took about two hours and I used the grade 8 9/16” bolt kits to replace the OEM bolts. I found the handling has improved with a significant reduction of my Jeep wanting to wander on unpaved and paved roads. I strongly recommend the Teraflex bars to any Jeep owner wanting to beef up the undercarriage and improve the ride of their Jeep.
