The SPC Zinc Alloy axle shim is a heavy-duty alignment shim sold six per box for tandem trailers and trucks. It offers superior compression strength compared to aluminum and brings hardness on par with SPC’s manganese bronze shims for improved durability. Typical use is precise front or rear axle alignment on over-the-road equipment where longer-lasting shim performance is desired.
