SuperPro Rear Upper Control Arm Set for 2007-2026 Jeep Wrangler; 2018 Jeep Wrangler JK

Unlock improved suspension geometry, drivetrain alignment, and off-road capability with the SuperPro HD Adjustable Rear Upper Control Arm Set for Jeep Wrangler JK and JL. Designed specifically for lifted Wranglers, these heavy-duty rear upper control arms provide an effective solution for correcting pinion angle after suspension modifications. As lift heights increase, factory control arms can compromise driveline angles and overall vehicle handling. The TRC1186 kit allows precise off-vehicle adjustment, helping restore proper geometry while improving both on-road drivability and off-road performance. Suitable for vehicles with lifts up to 4 inches (100mm), this kit is an ideal upgrade for enthusiasts looking to maximize the performance of their suspension system.

Supplied as a complete left and right control arm set, each arm comes fully assembled with SuperPro polyurethane bushings engineered for durability, longevity, and consistent performance. Developed and tested by SuperPro's Australian R&D team, these control arms are designed to withstand the demands of serious off-road use without introducing unwanted noise, vibration, or harshness. Whether used as a standalone upgrade or combined with SuperPro's adjustable front and rear lower control arms, the TRC1186 kit delivers the strength, adjustability, and reliability needed for trail-ready Jeep builds.
