SPL Parts FKS Rear Knuckle Monoball Bushings (RKB) for the 1989-1994 Nissan 240SX (S13) 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 FKS series spherical bushings feature FK Racing Bearings with a self cleaning and lubricating Teflon liner for long life and maximum performance. Highly precise (machined to 1/1000th inch) CNC machined 6061-T6 Billet Aluminum bearing shell provide an accurate fit.

Sold as a complete kit for one car. Made in the USA.
