SPC Performance 71054 Gm Rear Toe Shim - 40

The SPC Performance 71054 is a fixed-change rear toe alignment shim designed for GM vehicles equipped with twist beam rear axles. This precision shim delivers a repeatable ±0.40° toe change—either positive or negative—allowing technicians to dial in rear toe quickly and accurately without the guesswork of adjustable components.

Key Features:

• Delivers a precise ±0.40° fixed toe change in a single shim
• Compatible with SPC camber shims (part numbers 71051–71056) for combined toe and camber correction in one installation
• Stackable design—up to two shims can be stacked to achieve greater correction values
• Engineered specifically for GM twist beam rear axle applications
• Part of SPC's comprehensive GM rear shim system, available in toe increments of ±0.10°, ±0.20°, ±0.30°, ±0.40°, and ±0.50°

SPC Performance's stackable fixed-change shim system gives alignment technicians a fast, reliable method for correcting out-of-spec rear toe on applicable GM platforms. Pair this toe shim with a compatible SPC camber shim to achieve the exact combination of toe and camber correction needed in a single service.
