Product Description

The Whiteline KTA204 adjustable rear upper control arm is engineered for the 2005-2010 Ford Mustang S197 chassis--including V6, GT, and Shelby models--offering significant enhancements in rear-end stability and traction. Constructed from CNC-machined 4130 chromoly steel with a durable powder coat, it matches the larger Ford upper-arm length introduced in 2011 to reduce brake hop and axle tramp on lowered or performance builds.

Featuring a synthetic elastomer bushing with pinhole voiding and an eccentric crush tube adjuster, this arm allows on-car tuning of pinion angle without weakening the structure. Ideal for track or street use, it alleviates driveline lash during hard braking and acceleration, improves power delivery, and enhances exhaust sound and ride quality. Sold per side with a 3-year/60,000-mile warranty, it's a durable upgrade for Mustang enthusiasts.
