Callies LS7 Compstar Crankshaft 4.00 Stroke Long Snout

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.

Compstar LSX cranks are sold rough balanced to 1785 grams, or finish balanced to your bob weight.
