The Skyjacker contour degree shim helps correct axle and spring alignment with a 2.5‑inch width and contour profile suited to certain spring seats. Manufactured from aluminum alloy with pre‑drilled center holes, the shim adjusts axle geometry to improve spring placement and handling. Intended for use where contour matching is required, it supports wide springs on top of the axle and carries a limited lifetime warranty.
