Rebel S Racing Product's rear spring plate bushing set provides a semi-solid and super low friction design intended for both street cars and fully dedicated track machines. The maintenance free, replaceable bushing inserts are guaranteed to last as long as you own your car. Inner and outer bushing housings as well as stainless steel races are precision CNC machined. Zero deflection at suspension pivot points will provide both street and race cars with optimal geometry. Stainless steel inner races combined with the super low friction coefficient of the bushing sleeves allows the spring and shock to function properly without having resistance from the old rubber bushings or undersized polyurethane types. This performance upgrade produces a more tunable, predictable, and comfortable rear suspension. Made in the USA.
