Global West Control Arm Bushing Kit fixes the common problems found with the C5/C6 Corvette front control arm bushings. These 1/2 in. Del-a-lum bushings for the lower control arms are a direct replacement and quickly and effortlessly press into the lower arms. These bushings work like a bearing with plastic internal parts acting as a kind of insulation from metal to metal contact. The Global West Control Arm Bushings are lubricated with a grease fitting to provide up and down mobility without binding and stop the lower arm from moving side to side, preventing the car from "hunting" or following the road surface. Global West Control Arm Bushing Kits use special ball shaft upper mounts that change the alignment process by replacing the eccentrics with shims. This design fixes the "slip" that plagues eccentrics causing the alignment to shift under load.
