Our SPL FKS monoball bushings for the rear upper control arms 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 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 shelsl provide an accurate fit.
Kit complete for one car.
