SPC Performance 82130 Gm Hiper Strut Cam Kit

The SPC Performance 82130 is a front camber cam bolt kit designed as a reusable, heavy-duty replacement for GM's torque-to-yield (TTY) bolts used in the HiPer Strut suspension system found on select Buick and Cadillac models. Unlike the OEM Grade 10.9 TTY bolts — which must be discarded and replaced every time a wheel alignment is performed — SPC's upgraded Grade 12.9 bolts are engineered to be reused across multiple alignment services, reducing long-term maintenance costs.

On vehicles equipped with GM's HiPer Strut system, front camber adjustment is made via a cam bolt at the knuckle assembly. The slotted upper hole accepts SPC's eccentric cam bolt to provide the adjustment range, while the lower hole accepts a standard replacement bolt. This kit contains enough hardware to service one wheel/corner.

Key Features:

• Upgraded Grade 12.9 bolts replace OEM Grade 10.9 torque-to-yield bolts
• Reusable design — no need to replace bolts at every alignment
• ±2.0° front camber adjustment range
• Cam bolt fits the slotted upper hole; standard bolt fits the lower hole
• Kit contains 2 bolts — sufficient for one wheel/corner
• Estimated installation time: 0.3 hours per side
• One kit required per wheel
• CARB eligible

The SPC Performance 82130 is the smart, cost-effective solution for alignment shops and enthusiasts who regularly service GM HiPer Strut-equipped vehicles and want to eliminate the recurring cost of OEM TTY bolt replacement.
