Lunati engineers designed the NASCAR® rule series cranks to make it easy for stock car series racers requiring crank weights in the 50 lbs. range. These cranks are available rough or finished balanced to your bob weight. In addition these crankshafts have the rear of the counterweight squared, all rod journals are drilled and the counterweight heights will accommodate a 5.700 inch RL. The benefits of this advanced design is faster acceleration with superior oil control.
