LSX 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 LSX crankshafts available anywhere. Regardless of whether your application is a road race, marine, circle track, or street/strip, Compstar has the configuration you need.

Made from 4340 steel deep nitrided for strength and wear resistance, every Compstar crank is intended for high-output installations. Compstar LSX crankshafts are counterweighted to improve bearing load distribution, allowing them to withstand both high boost and high-RPM applications.

Machined with large journal radii, gun-drilled mains, and fully lightened rod journals, the Compstar LSX crankshaft is truly built for performance.  To accommodate your engine control system, Compstar LSX shafts can be specified with either the late LS2 – LS7 58-tooth or the early LS1 – LS6 style twin timing wheels. If you are building an LS7-style dry sump engine, Compstar offers an extended-length post to easily complete your project.
