SPC Performance 87400 heavy-duty camber and caster cams replace the upper control arm mounting bolts on 1988-2005 GM full-size trucks and SUVs. The original bolts are removed and replaced with the cams, which are rotated to provide camber and caster adjustment. On some applications the OE slugs are removed and the bolt holes elongated with the SPC 74910 punch. The 14 mm x 2 steel bolts carry a zinc oxide finish and are supplied as a set of four, enough for both sides.
