Howards Racing Components Billet Reaper Crankshaft
Billet steel crankshafts are stronger because they have a uniform and non-stress grain structure. These cranks start with E4340 AQ bar stock material and are precision CNC machined. They feature large fillet radii and lightening holes in all rod journals. Fully stress relieved and shot peened. Nitrided for superior wear resistance. Rod and main bearing journal surfaces are micro polished.
