Ford Shelby GT500 Control Arms - Front - BMR Suspension - Lower A-Arm Kit - Red - `11-`14. These BMR AA758R lower control arms are a direct-fit front suspension upgrade engineered for 2011–2014 Mustangs and Shelby GT500s, designed to address A-arm deflection and improve front-end behavior under launch and hard driving.

Constructed from heavy-duty 4130 chromoly steel with 6061 aluminum components and finished in a durable red powder coat, this kit replaces factory A-arms with race-focused hardware. The AA758R includes new 19mm ball joints and Grade 8 hardware to deliver consistent geometry and improved steering feel. By reducing A-arm flex and narrowing track width 1.5" overall, these lower A-arms help maintain alignment under load for better stability during drag launches and aggressive street use. Lightweight construction keeps unsprung mass down while maintaining strength for performance applications.
