Wrangler JL 2018-2026 Jeep 4WD - Adjustable Rear Upper Control Arms by JKS

JKS1666 J-Flex Adjustable Rear Upper Control Arms are engineered to improve suspension geometry, articulation, and durability on Jeep Wrangler JL models. Designed for both stock and lifted applications, these heavy-duty control arms allow precise correction of rear axle positioning and pinion angle while maintaining a smooth, controlled ride on the street.

Constructed from high-strength DOM tubing and CNC formed for proper tire, frame, and axle clearance, these arms provide a substantial upgrade over factory components. The adjustable design incorporates a forged flex joint at the frame-side mount with heavy-duty threads and a jam nut for secure, accurate length adjustment. The flex joint allows up to 30 degrees of misalignment for impressive articulation and is fully greaseable and rebuildable for long-term serviceability.

At the axle mount, premium OE-style rubber bushings reduce noise, vibration, and harshness while delivering maintenance-free operation. Finished in a durable gloss black powder coat and sold in pairs, JKS1666 rear upper control arms deliver strength, adjustability, and dependable performance for daily driving and demanding off-road use.
