Product Description

The Whiteline KTA205 Adjustable Rear Upper Control Arm is engineered specifically for the 2011-2014 Ford Mustang (S197 chassis), including V6, GT, and Shelby GT500 models. Crafted from 4130 Chromoly and featuring a synthetic elastomer bushing, this arm enhances rear-end stability, eliminates brake hop, and controls axle tramp for improved track and street performance.

Equipped with an eccentric crush tube adjustable from 221-250 mm, the KTA205 allows for on-car pinion angle tuning--especially useful after suspension changes or drag racing setups. Designed for direct bolt-on installation (sold individually), it requires wheel alignment once installed. Ideal for owners seeking better traction, sharper handling, and consistent rear grip under acceleration and braking.
