Lifter bodies are FEA-engineered to provide an optimum balance of superior strength at minimum weight. Crane's race-proven Bearing-Focused oil system features small channels in the lifter body to lubricate the needle bearings. The roller wheel/bearing/axle combinations are optimized per lifter diameter, 1.062" diameter lifter has a .920" diameter wheel.
