GM's HiPer strut has been released on several Buicks and Cadillacs. To adjust front camber you must adjust a cam bolt on knuckle assembly. However, GM is using torque-to-yield bolts which require replacement whenever an alignment is performed. Replace the OE 10.9 Grade torque-to-yield bolts with SPC's upgraded 12.9 bolts and you will not need to replace the bolt for future alignments. The kit includes 2 bolts; a cam bolt for the slotted upper and a standard replacement bolt for the lower hole, enough toalign one corner. California Residents WARNING Installation Instructions
