Whiteline 11-14 Ford Mustang GT/Shelby GT500 (S197) Adjustable Rear Upper Control Arm

If you're looking to get a better handle on your 2010-2014 Ford Mustang GT or Shelby GT500 during hard braking or acceleration, this adjustable rear upper control arm from Whiteline is a solid option. The stock setup on the S197 chassis can sometimes lead to brake hop and axle tramp, especially when you're pushing the car. This control arm is built to help minimize those issues, giving you a more stable and predictable rear end.

Whiteline constructed this arm from strong 4130 Chromalloy, a material known for its durability. It features a longer arm length, similar to the update Ford made in 2011, which directly helps reduce brake hop. Instead of harsh bearing designs, it uses a synthetic elastomer bushing that offers improved rear-end stability without making the ride uncomfortable. Plus, it has an eccentric crush tube that lets you adjust the pinion angle and instant center without weakening the arm, and a unique pinhole voiding feature that allows the bushing to move freely without binding. The heavy-duty mount adds rigidity and is designed to fit all S197 chassis models.

This control arm comes with protective plating and powder coating to resist corrosion and withstand tough conditions, so it should hold up well over time. Whiteline also includes a detailed installation guide to help you get it fitted correctly.
