Steeda S550 Mustang Billet Rear Shock Mounts


Made from billet aluminium, Steeda Rear Strut mounts are designed to replace the weak cast factory units. The factory mounts use a rubber bushing that binds & collapse on cars with lowered or aggressive shocks, the Steeda spec stainless steel spherical Teflon lined bearing gives optimum performance and control.

Made from billet 6061 aluminium, these mounts are designed to replace the weak cast factory units. Unlike the factory mounts that have a rubber bushing that binds and will deteriorate over time on lowered cars or cars with aggressive shock settings, these units feature a Steeda spec stainless steel spherical Teflon lined bearing for optimum performance and control. Steeda also went a step further by making multiple kits, one for factory and Ford Racing shocks that are 10mm in diameter (555-8151) and one for aftermarket shocks like our Pro-Action that are 12mm in diameter (555-8152). If you are running stock shocks now but might upgrade to Pro-Actions in the future, no problem, there is no drilling required like the OEM mounts, these mounts are upgradable with a simple spacer and nut change (555-8153). 

The Steeda Billet Shock Mounts are a great upgrade to drag racers and road racers alike, or if you're running aggressive shocks on your car, these will greatly help with control with uncompromised durability.
