SPC Break Away axle shims are heavy‑duty caster shims used to adjust pinion angle on Jeep CJ and similar vehicles with 1‑3/4" to 2" wide leaf springs. The six‑shim pack provides a 4° taper for larger axle alignment correction. Heavy‑duty sizing and repeatable increments make these shims suitable for tougher axle adjustments. Six shims per box and 1‑3/4" width standardize inventory for workshops.
