05-14 Mustang GT Rear Lower Control Arm Kit

The 05-14 Mustang GT Rear Lower Control Arm Kit (MPN: M-5538-A) is an aftermarket suspension component designed for fifth-generation Mustang GT owners who demand factory-correct geometry and durability. If your Mustang's rear suspension feels loose, produces clunking sounds over bumps, or exhibits excessive wheel hop during acceleration, worn lower control arms are the likely culprit.

This kit replaces both rear lower control arms in a single purchase, restoring precise wheel alignment and eliminating play that degrades handling and tire wear. Each arm features ball joints and rod end geometry that work in concert with the integral link design to control vertical wheel motion while allowing lateral compliance—critical for both street comfort and track stability. The powder-coated steel construction resists corrosion and impacts, ensuring durability.

Replacing both arms as a kit guarantees matched wear characteristics and symmetrical suspension response. This kit is essential for any 2005–2014 Mustang GT owner experiencing suspension noise, uneven tire wear, or those rebuilding a worn rear suspension after high-mileage use or track duty. Installation requires a four-wheel alignment after installation to ensure optimal performance.
