6061 T-6 Aluminum Control Arms

The Steeda aluminum lower rear control arms provide increased traction and handling by eliminating suspension bind. These components are constructed from high-strength extruded 6061 T-6 aluminum, reducing unsprung weight by 32% compared to OE parts. The 4500 series design is specifically optimized for street cars, road racing, and occasional drag strip use, offering lower noise, vibration, and harshness (NVH) levels than units equipped with spherical bearings. These control arms feature an exclusive three-part variable rate bushing system that controls the axle for improved handling while maintaining a smooth ride. The sway bar mounts are strategically located to ensure clearance for differential stud girdles and T-Rex fuel pumps. They are a direct bolt-on installation, providing a lightweight alternative to heavier lift bars. Important fitment information: these control arms are designed for 1999-2004 Mustang models, but do not fit the 1999-2004 Cobra.
