Whiteline 05-10 Ford Mustang Adjustable Rear Upper Control Arm

The S197 Mustang chassis, from 2005 to 2010, often experiences brake hop and axle tramp due to the stock upper control arm and its soft bushings. Whiteline's adjustable rear upper control arm is built from strong 4130 Chromalloy steel, featuring a longer arm length similar to the design Ford introduced in 2011, which helps significantly reduce brake hop.

This control arm uses a synthetic elastomer bushing that offers improved rear-end stability without the harshness found in bearing-style bushings. It includes an eccentric crush tube, allowing you to adjust the pinion angle and instant center without weakening the arm. The bushing also has pinhole voiding to allow articulation without binding, and a heavy-duty mount adds rigidity. All metal components are protected with plating and powder coating to resist corrosion and withstand tough conditions.

This part is designed to optimize your vehicle's pinion angle, which can minimize vibration and help put more torque to the wheels. An installation guide is included to help you through the process.
