Part Premiere: RB4021-Rear Upper Control Arm Mount

Introducing our latest parts of your TJ Wrangler, our Rear Upper Control Arm Mount (RB4021L & RB4021R).

Due to vehicle frames being designed to support moderately heavy cargo loads in trunk spaces and, in the case of Jeeps, cargo storage, the high arch of the rear control arm mounts takes a heavy toll over the years of constant up and down impacts.  Especially if you’re a heavy trail rider.  In time, one of the most frequent failures in Jeep frames is the control arm section and mounts, completely disabling the vehicle.

Our Rear Upper Control Arm Mount is a quick and easy solution to get your Jeep back on the road, when other more expensive options push you away from your passion.  This part is a great option when you don’t need the entire frame rail and just want to repair the mount. It’s CAD designed and laser cut to factory specifications, meaning the installation to go without a hitch.

You can pick up your own Rear Upper Control Arm Mount at the link below.  And when you do, be sure to check out our fully written instructions or our start to finish video walkthrough,
