Steeda S550 Mustang Billet Rear Shock Mount - 10mm Rear Shocks (OEM)

Once the aftermarket shocks started coming out for the S550 Mustang, people all across the country ran into issues breaking the factory rear shock mount. Whether it was drag racing or road racing with very stiff shocks, customers were having all sorts of issues. 

Thatís when the team at Steeda got together to come up with a solution. 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 8160 Kit provides for Steeda's own Pro-Action NON ADJUSTABLE fixed rate shocks and KONI shocks, while the now discontinued 8161 kit was tuned for KW Coilovers, and also for Roush, Bilstein and Vogtland kits.

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