SPC zinc alloy axle shims (six per box) provide a stronger alternative to aluminum for aligning axles on heavy-duty trucks and trailers. With increased compression strength and hardness, these shims resist crushing when used with Z blocks or axle spacers. They’re a practical choice for precise axle alignment tasks and come in the specified width, length and taper to match common heavy-duty applications.
