SPC Performance aluminum axle shims offer a cost-effective option for over-the-road truck and trailer caster correction. Sold six per box, these shims provide average compression strength and hardness, and are available in multiple sizes. Use with proper load-spreading when Z-blocks or axle spacers are present to prevent shim crushing and ensure stable caster alignment.
