LS Series for dry sump snout, 4340 non-twist forging, unbalanced for the GM LS7 (dry sump). All cranks are stress relieved, shot peened, magna flux inspected and nitrided (multi step heat treatment) for ultimate performance. Fully profiled counterweights are designed for reduced windage through the crankcase creating less oil resistance for better rpm potential. Add $250 for precision balancing with provided bobweights.
