SPC Performance 71051 Gm Rear Toe Shim - 10

The SPC Performance 71051 is a fixed-change rear toe alignment shim designed for GM vehicles equipped with twist beam rear axles. This precision shim delivers a direct positive or negative toe change in a ±0.10° increment, allowing technicians to dial in rear wheel alignment quickly and accurately without guesswork.

Part of SPC's stackable shim system, the 71051 is designed to work in combination with compatible camber shims (part numbers 71051–71056) to achieve the exact combination of toe and camber correction required. Up to two shims can be stacked together, enabling incremental corrections up to ±0.20° of toe change from this shim alone.
