These three thin wrenches are just what is needed to set the adjustable lifters. It eliminates the need to grind down your own wrenches to make them fit the nuts. They are thin so that they fit into the tight confines of the adjustable part of the lifter.
Works on all style adjustable lifters. One wrench is shaped to fit on the lifter. The other two are used for the adjustment bolt and if necessary the lock nut. One has a straight head and one is curved to allow greater flexibility in getting the wrench on the bolt or nut.
