Machined grease grooves transfer lubrication throughout the bushing which promotes bushing life and assures a quite ride. Special thrust washers isolate the bushing housing from the frame and maintain proper control arm position. Plastic inserts with grease groove and holes provide smooth control arm movement without deflection or bind. The insert also serves to isolate the aluminum housing from the steel sleeve. Bushings are a direct replacement.
Upper arm provides more negative camber for improved tire life and cornering.
Caster has also been increased which provides straight line stability and improved camber gain. Upper ball joint angles are corrected. Upper control arms reduce positive camber gain which provide greater cornering ability. We do not recommend polyurethane in this location. Upper control arm bushings have grease fitting for easy bushing lubrication.
