SPC Performance Zinc Axle Shims

SPC Performance Zinc Axle Shims are heavy-duty tapered alignment shims. They adjust axle caster angle on solid-axle vehicles. They can also correct pinion angle, so they work as both caster shims and pinion angle shims. Each variant in the line offers a different degree of taper, so you can dial in the correction your alignment needs.

Key Features:

• Zinc construction: Zinc alloy gives better compression strength and hardness than traditional aluminum shims.
• Heavy-duty design: Built to hold up to the loads on solid-axle suspensions.
• Caster and pinion angle adjustment: Lets you change caster, and also pinion angle, on solid-axle applications.
• Precise taper: Machined with a defined degree of taper, so each shim gives a predictable amount of correction.
• Breakaway design: Select variants have a breakaway portion so the shim can be sized to narrower leaf springs.

These axle shims suit alignment technicians, off-road builders, and restoration shops. They help restore correct axle geometry after a lift, a suspension change, or wear. Choose the variant whose degree of taper matches the correction required. SPC Performance (Specialty Products Company) is a long-established name in alignment parts.
