SPC Zinc axle shims provide a compact solution to correct caster by up to ±4° with a single part number. These heavy‑duty zinc alloy shims feature a double breakaway design and sizes that cover 3"–3.5"–4" pad widths, letting a tech change caster in small increments. Built for solid‑axle RWD and 4WD vehicles, the six‑piece pack aims to reduce inventory while expanding adjustment coverage.
