Callies Compstar Crankshaft - Gen V - LT - 4.000 Stroke - 58X

Gen V LT engines are taking the performance market by storm. To answer the needs of engine builders who are testing new limits, Compstar has developed the widest range of LT crankshafts available anywhere. Regardless if your application is road race, marine, circle track, or street/strip, Compstar has the configuration you need.

Made from 4340 steel that is deep nitrided for strength and wearability, every Compstar crank is intended for high output installation. Compstar LT crankshafts are counterweighted for enhanced bearing load distribution, which allows these shafts to withstand both high boost and high RPM applications.

Machined with large journal radii, gun drilled mains, and fully lightened rod journals, the Compstar LT Stroker crankshaft is truly built for performance.  If you are building a wet sump LT style engine, Compstar offers an extended length post to easily complete your project.

NOTE: Not for use with “Dry Sump” engines
