      Tested Tough Design. The folks at TeraFlex are enthusiasts just like you and love Jeeps of all types, whether modified or not. They have been making parts and accessories for your Jeep since 1996 and are committed to providing the best parts possible. Lifting your Jeep means modification and requires parts to make the most of that modification. The TeraFlex Alpine Rear Upper FlexArm will allow you to dial in your 2" to 4" lift perfectly and center your wheels while not restricting any articulation or flex when you are off-road.

      Solid Construction. Built with 2" to 4" lifts in mind, these flexarms are adjustable and durable with the 1-5/8" x 0.157" wall of the tube being a DOM (Drawn Over Mandrel) type tube for maximum strength. The bushings are a factory style bushing that provide factory style characteristics with no maintenance and the 6061-T6 aluminum clap collar secures the rod end after you have adjusted it. The main body is black e-dipped for corrosion resistance and long life.

      Easy Installation. These flexarms have an adjustability of over an inch and were designed to install into the factory control arm mounting locations.

      Limited Lifetime Warranty. TeraFlex extends a Limited Lifetime Warranty on all of its products to be free from defects in material and workmanship. For complete details and terms, contact TeraFlex directly. Note that failure to complete regular maintenance on TeraFlex flexarms (grease every 3,000 miles) will void this warranty.

      Application. The TeraFlex Alpine Rear Upper FlexArm fits 2007-2018 Jeep Wrangler JK Models.

      Note: The TeraFlex Rear Upper Flexarm is available individually for either the driver or passenger side and is also sold as a pair.

        5 2017 Rubicon - MichaelSlinkard


        Took longer to put on than I thought. Once on, I took to get alignment done. All done. Wow, what a difference in the suspension and handling. All much better than stock. I have a 5 inch front lift and a 4 inch rear lift. Running Cooper Discoverey STT PROS 37x12.50x17 on DV8 17x8.5 beedlock wheels. All works great. Street handling better not mushy at all. Now the good stuff, OFF ROAD PERFORMANCE, these arms flex like crazy. Very Very HAPPY with my choice to get these arms and not the double Heim Joint model. I have heard some horror stories about those arms wearing out very quickly. Even with proper matitance. I highly recomed thes arms. I use my JK for what it is made for.

        5 2010 Wrangler - PeterF

        Rear adjustable uppers

        Very well constructed control arm. Packaged nicely. Fairly easy install. Plag nuts an the JK are a little bit of a pain. Made it easy to correct my rear driveshaft pinion angle.
