SPL Parts - Rear Knuckle Bushings (RKB) - BMW E36/E46 M3 ^Sale

SPL Parts FKS Series BMW E36/E46 Rear Trailing Arm Bushings (RTAB) 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 the toe change under high load that the OEM bearing would allow.

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 a pair. Made in the USA.
