SPC zinc axle shims provide twice the coverage in a single part with double breakaway capability, changing caster positive or negative from 0.5° to 4°. Built from heavy‑duty zinc alloy, these shims suit any solid axle RWD or 4WD vehicle and offer versatile caster correction with fewer distinct parts. They’re intended to reduce inventory while covering a broad adjustment range.
