SPC Performance 45938 Alignment Socket Steel Natural for Chevy/GMC 4WD Each

Aligning these trucks can be difficult because it is impossible to access the head of the cam bolt to adjust alignment angles. This special grooved socket fits over the end of the bolt allowing the technician to turn the alignment cams to change alignment angles after loosening the lock nut. CAUTION: Not for use with impact wrenches (air tools)
