The 6-pc Caster Camber Kit for GM, No. 41620, from Lisle Corporation offers a holding tool that surrounds the entire perimeter of each cam to provide a non-slip work area when moving the hard-to-reach and often rusty OEM cams on 1999 and newer GM 1/2, 3/4, and 1-ton vehicles with coil spring front suspensions. The 14-1/2" long 21mm/24mm wrench can be conveniently used from the bottom side of the vehicle instead of reaching through the wheel well which saves technicians time. Holding tools work with 27mm applications that can be used with a standard socket or wrench.
