Compweight Big Block Chevy
Drawing from the deep history of experience at Callies, our Compstar engineers have been able to combine the best characteristics of performance crankshaft design into the Compstar “Compweight” for Big Block Chevy applications Produced from 4340 material that is triple heat treated and stress relieved during machining. Compstar BBC Compweights will remain true during severe duty use.
All Compstar Compweights are center counterweighted for reduced bearing loads during high RPM use. Machined with .125 journal radii and conventional straight shot oiling, these cranks offer simple durability. With all 4 rod journals drilled, Compstar BBC Compweight cranks weigh in at 75lbs or less. Compweights are fully deep case nitrided.
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 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 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. To accommodate your engine control system, Compstar LSX shafts can be specified with either late LS2 – LS7 58 tooth or the early LS1 – LS6 style twin timing wheels. If you are building a dry sump LS7 style engine, Compstar offers an extended length post to easily complete your project.

Ford Coyote engines have proven their exceptional capabilities both at the track and on the street. Callies Compstar 4340 Steel Crankshafts were designed to support the additional horsepower and torque being generated in these applications. These cranks are machined with large strength enhancing journal radii like all Compstar crankshafts and come nitrited. These cranks are available in three configurations. A stock 92.7mm stroke with “Standard” Coyote Rod journal, a 96.5mm (3.800″) stroke and a 99.06mm (3.900″) stroke. All standard OEM driveline, valvetrain and accessory components can still be utilized.
Every aspect of this crank has been meticulously engineered. It starts up front with a post that is dual keyed to securely locate supercharger drive pulleys, and ending with journals that are super finished. For ease of assembly, rod journals are standard SB Chevy diameter and width. Counterweights have been profiled for 6.125 inch connecting rods.
Compstar Hemi cranks are manufactured from 4340 steel and range in stroke from 3.800 – 4.080. Also for improved crank case ventilation and reduced weight, main journals are gun drilled.
