SPL Parts FKS 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.
SPL 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 6061-T6 Billet Aluminum bearing shells provide an accurate fit.
