These over-the-road heavy-duty alignment shims are intended for fast, accurate front or rear axle alignment on popular tandem trailers and trucks. Supplied six per box, they serve as spacers for Kenworth Air Glide "Eight Baggers" and help complete heavy-duty truck alignment tasks reliably. Use them where specified to adjust thrust angle and toe by placing the shim between the spring hanger and the spring.
