SPC zinc alloy axle shims (six per box) are engineered for over-the-road heavy-duty trucks and tandem trailers to align front or rear axles. Zinc alloy offers improved hardness and compression strength versus aluminum, providing better load resistance when used with axle spacers or Z blocks. Each part number supplies six shims; use them to fine-tune pinion or caster alignment reliably.
