      Construction. TeraFlex provides this tough as nails FlexArm system for your JK. Within the kit there are three different end types: solid forged steel, rubber bushing ends, and urethane bushing ends. These control arms feature a solid steel shank and grease fittings to keep the joints properly lubricated.

      Features. A lifted suspension should perform exactly as you expect it too. However, aggressive systems can mess up your JK's drive train angles which is where this TeraFlex kit comes in. This kit provides up to 4 inches of adjustment, allowing you to setup the suspension for on-road usability or extreme trail tackling finesse. Three end options are included, along with built-in grease fittings to protect the joints from the rigors of the trail. No matter what lift kit you've used, the TeraFlex FlexArm system can help you set the right caster and pinion angles to reduce tire and driveline wear. This kit will also significantly improve suspension and steering performance. You can also center your Wrangler's axles with this kit to optimize suspension travel.

      Application. This kit fits on 2007-2018 Wrangler JK models with any type lift kit.

        5 2014 Rubicon - RichardL

        Teraflex Flexarm on JKU-R 2014

        I used this to correct the shortcomings of my 4.5" AEV RS lift kit. A 4-4.5" lift needs more than just a cam bolt or drop bracket for proper geometry. The TeraFlex arms went on easily and were no issue to adjust to the length I wanted. I was able to move the back axle back to center and easily clear the 37" Goodyear MTRs. After installing the arms I had a local shop do a true alignment. Now I have much less bump steer and no rubbing in the rear. Definitely happy with the new arms.

        These are exactly what they seem - sturdy, easily adjustable, and good looking! I would absolutely recommend them. I cannot speak for the other, cheaper options, but these are solid!

      Does anyone know the measurements for the front upper and lower control arms for a 4 inch lift?

      Can I use these with a 4.5 inch lift kit

      • This will work with any type of lift kit.

      Are these adjustable while installed or do you have to remove one end to adjust the length?

      • The Teraflex Complete FlexArm System will require one end to be free from the vehicle to adjust the length.

      I’ve got the Teraflex 2.5” lift with 9550 shocks. I’m still running the stock control arms. Would these adjustable ones really be necessary or are my caster and pinion angles still within a good operating range? I daily drive my Jeep with maybe once a month mild off-roading.

      • At 2.5" of lift theTeraflex Complete FlexArm System would not be required unless you notice issues with your angles that need to be replaced or you are trying to fine-tune your suspensions.
