Whiteline Rear Upper Control Arm – 2011-2014 Ford Mustang

Quality Rear Upper Arm for the S197 Mustang
Whiteline’s rear upper control arm for the 2011-2014 Ford Mustang (S197) is a quality replacement for the factory rear upper arm — the component that controls rear axle alignment geometry on the S197’s solid rear axle setup. A correctly functioning rear upper arm with fresh bushings maintains proper pinion angle and limits axle hop under hard acceleration.

S197 Solid Axle and Rear Upper Arm
The S197 Mustang uses a solid rear axle with a traditional four-link geometry including upper and lower control arms. The upper arm controls fore-aft axle positioning and, importantly, pinion angle — the angle of the driveshaft. Worn upper arm bushings allow the axle to rotate under hard acceleration (axle wrap), producing the characteristic wheel hop that S197 Mustang owners are familiar with.

Reducing Axle Wrap
Quality upper arm bushings resist axle rotation under hard acceleration loads. A replacement arm with fresh bushings is an improvement over a worn OEM arm with degraded rubber — reducing axle wrap and the wheel hop it produces.

Track and Performance Mustang
For S197 Mustangs used for drag racing, road course work, and autocross, rear axle control quality directly affects performance. A fresh upper arm is a fundamental component of rear axle maintenance.
