SPL Parts FKS GTR R35 Rear Upper Control Arm Monoball Bushings (RUAB) 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 Parts 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 aluminium bearing shells provide an accurate fit.
