The SPC aluminum axle shim is an economical alignment shim sold six per box for over-the-road truck and trailer caster correction. At 3" x 6" with a 0.5° taper, it offers average compression strength for technicians needing a low-cost means to adjust caster. When using Z blocks or axle spacers, spread load to help prevent shim crushing during service.
