SPC Performance 71034 Gm Rear Toe Shim - 40

The SPC Performance 71034 is a fixed-change rear toe alignment shim designed for GM vehicles equipped with twist beam rear axles. This precision nylon shim delivers a ±0.40° toe correction per shim, allowing technicians to dial in rear wheel alignment quickly and accurately without the need for adjustable links or specialty hardware.

Key Features:

• Provides ±0.40° of rear toe adjustment per shim installation
• Stackable design — stack up to two shims for maximum correction range
• Combine with a compatible SPC camber shim to achieve both toe and camber corrections simultaneously
• Full-contact nylon construction for consistent, reliable alignment change
• Available in incremental angles — part of a complete shim system for precise alignment control
• No drilling or modifications required for installation

The 71034 works as part of SPC's GM rear shim system, which offers camber changes in ±0.25° increments and toe changes in ±0.10° increments across the product family. Pair with a camber shim from the same series to address multiple alignment angles in a single service. Sold individually.
