SPC Performance zinc axle shims provide a quick, accurate way to align front or rear axles on most tandem trailers and heavy-duty trucks. Made from a zinc alloy for improved hardness and compression strength compared to aluminum, these shims are offered in a 3 in by 6 in, 3.0 deg profile. Sold six per part number, they can be used with Z blocks or axle spacers to spread load and prevent shim crushing.
