Made from 4340 steel that is deep nitrided for strength and wearability, every Compstar crank is intended for high output installation. Compstar LSX 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 LSX crankshaft is truly built for performance. For tall deck block engine builds, strokes up to 4.250 inch can be specified to create large, reliable CID. Should you wish to reduce rod journal surface speed, 2.000 inch journal diameters are available.
Compstar LSX cranks are sold rough balanced to 1785 grams
