K1 Technologies Nissan SR20 series crank lineup includes premium quality 4340 steel billet SR20 cranks. We are proud to be a distributor for the entire line of K1 SR20 engine products. K1 Tech produces extremely strong 4340 billet SR20DET / SR20 crankshaft assemblies that are machined to very close tolerances and are far stronger than a stock crankshaft.

The SR20 engine family is known for being a tough, reliable power plant than can be built to produce much more power than stock. If you are building a normally aspirated engine, or one for use with nitrous, a supercharger, or a turbo SR20DET we have the parts needed to improve your engines torque, horsepower and reliability.

This crank fits the SR20 engine series which includes the SR20, SR20DET and other engine models based on this engine family.
