SPL Parts FKS Series Rear Knuckle Monoball 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.
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.
