Description

Front Caster Rod Bushings (CRB) replace the stock flexible rubber bushings with low friction, articulating Spherical Bearings eliminating bushing deflection and reducing friction. This maintains optimum suspension geometry under load to improve braking and handling feedback. Massive 1" sized FK Racing Bearings with self lubricating Teflon liners are used to ensure maximum performance and durability. Innovative CNC machined offset bearing spacers provide +/- 2 degrees of caster adjustment. OEM arms not included. Sold as a pair. Made in the USA.

Features:

  • Proudly made, engineered, and assembled in the USA.
