SPL Race Front Caster-Adjustable Upper Control Arm Bearings - E82, E9X, F8X

Eliminate deflection caused by the soft, fluid-filled stock bushing. The aluminum bearing housing has zero play to maintain alignment settings during it's full range of motion. The FK spherical bearing has offset inserts so you can adjust the caster setting of the arm. Bearings include a Teflon inner liner.

Designed for track/racing use only. Use of solid and spherical bushings will have more noise and harshness than any other material and are not recommended for street use.
