SPL Parts FKS Series Rear Knuckle Bushings (RKB) replace the stock mushy rubber bushings with low-friction articulating spherical bearings, eliminating bushing flex and reducing bind/friction. This maintains optimum suspension geometry under load to improve handling and feedback, and removes any camber and toe change that can occur under load.
Our Monoball Bushings feature FK Racing Bearings with a self lubricating Teflon liner for long life and maximum performance. Highly precise (machined to 1/1000th inch) CNC machined T6061 Aluminum bearing shells provide an accurate fit.
Sold as complete kit for one car.
