Anything higher than that, you'll want to go with a long-arm kit. I have these on a 4" lift, and the ride is pretty rough because of the suspension geometry (any short-arm control arms on that tall of a lift are going to be rough). **Q: Is this individual? Or sold as a pair?** A: It is a pair **Q: Does the pair come ready to install, including the bushes and sleves?** A: Yes it does. **Q: I added a 3.5 inch lift to my jku and now the back tire is to close to frame. Will this correct it?** A: You will need both upper and lower adjustable control arms to move the axel back to its original position. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Much stronger than stock and look better. *by V***G on August 9, 2023* Replaced my stock arms and extended these 1/4 inch over stock to push my axle back a smidge. They worked perfect. They were a bit of a pain for a driveway install but I got it done. It wasn't their fault as I believe any upper arm would have been just as difficult. Making them longer than stock is what made it more different to get them in place. I liked that the grease fittings on the frame side can be installed on either side of the bushing and comes with a plug for the hole not used. ### ⭐⭐⭐⭐⭐ Works with 3" lift *by G***N on September 18, 2022* I set them at 17 11/16". I didn't measure drive line angle, but it got my spring away from the track bar bolt on the the relocation bracket. Seems to have improved the ride a bit. ### ⭐⭐⭐⭐⭐ Easy to install *by M***L on March 18, 2019* If you lift your Jeep you'll need a pair of these bad boys to correct your pinion angle. Easy to install in the garage with a floor jack and basic tools. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/12612296-rubicon-express-re3757-rear-upper-super-flex-adjustable-control-arm](https://www.desertcart.pl/products/12612296-rubicon-express-re3757-rear-upper-super-flex-adjustable-control-arm) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
