Description
Callies Compstar LS1 crankshafts deliver proven race-grade reliability and precision engineering for high-performance GM LS builds. Designed with durability and ease of assembly in mind, each Compstar LS shaft features deep case nitriding for exceptional wear resistance, gun-drilled mains, and lightened rod journals to minimize rotational mass without sacrificing core strength. Prepped specifically for standard bobweights and cam-cleared for common rod lengths, these crankshafts provide an optimal balance of strength, performance, and value for competitive street and strip engines.
