Proflow Warlord Forged 4340 Steel Crankshafts

Proflow's Warlord forged 4340 steel crankshafts are great for high performance applications. They feature non-twist forging, undergo a multi-stage heat-treatment process, and are stress-relieved and shot-peened.

These cranks are X-rayed, magnafluxed, and sonic-tested, so you know you're getting a top-quality piece. Each crankshaft has chamfered oil holes for improved oiling, a .125 in. radius on rod and main journals for increased strength, and the journals are precision-ground and micro-polished to less than 5 R.A. A target bob weight of +/- 2 percent greatly reduces balancing time.

Many options are available; order the model recommended for your year/make and engine application.
