SPC zinc alloy axle shims (six pack) are a fast, accurate solution to align front or rear axles on over-the-road heavy-duty trucks and tandem trailers. The zinc alloy improves hardness and compression strength compared with aluminum. These shims are stackable and intended to be used with Z blocks or axle spacers to distribute load and prevent crushing while correcting alignment precisely.
