Howards Cams Track Smart 3 crankshafts are computer-designed and forged from premium 4340 steel. This process includes double stress relief operations that make these cranks dimensionally stable. After machining, the units are hardened with a deep nitride for superior wear resistance, ideal for abusive track environments. Properly placed counterweights improve balance and reduce bearing loads. All rod journals are drilled and counterweights are profiled for piston clearance. Track Smart 3 replacements crankshafts are available for specific Chevrolet engine sizes and strokes. Order the model recommended for your application.

These cranks start with E4340 aircraft-quality bar stock material and are precision CNC-machined. They feature bearing journals with large fillet radii (chamfered bearings required) and weight-reducing holes in all rod journals. Reaper crankshafts are available for fitment in a variety of big block applications. Additional product details: * Computer-designed center counterweights for reducing bearing loads and improved balance * Fully stress-relieved and shot-peened * Nitrided for superior wear-resistance * Rod and main bearing journal surfaces are micro-polished * Double keyways for dampers
