These are Solid Rear Knuckle Monoball Bushings that replace All of the OEM rubber parts which insert into the rear knuckle (pictured to the left).

SPL FKS monoball bushings for the rear knuckle 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 FKS series 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 shell provide an accurate fit.
