Thompson Motorsports carries a range of crankshafts including the ever popular, and affordable, K1 Technologies Forged Crankshafts.
K1 Technologies crankshafts are manufactured with premium 4340 steel that is core hardened using a Nitride process, in place of induction heat-treatment, to help increase strength and reduce stress. This nitride process for hardening eliminates softening between the journals and post-running deformations. K1 Crankshafts have a straight hole oiling system for improved lubrication, are magnetic particle inspected, and are held to a maximum tolerance of .0002 in journal dimensions.
