LT Gen-5 Crankshaft 3.622 Stroke

The LT Gen-5 Crankshaft 3.622 Stroke from Chevrolet Performance is a precision-engineered internal engine component designed for builders and enthusiasts seeking to maximize displacement and low-end torque in modern small-block applications. This OEM-quality crankshaft serves as the backbone of any serious engine buildup, converting reciprocating piston motion into rotational power with proven reliability and durability. Whether you're constructing a performance street engine, naturally aspirated race build, or forced-induction platform, a quality crankshaft is non-negotiable for achieving consistent power delivery and longevity.

The 3.622-inch stroke dimension is critical to understanding this component's purpose: stroke length directly determines engine displacement when multiplied by bore diameter and cylinder count, and this particular specification allows builders to create larger-displacement variants within the LT Gen-5 family without requiring block modifications. The crankshaft's weight of approximately 65.44 pounds reflects its solid construction and balanced design, essential for minimizing vibration across the RPM band and supporting higher cylinder pressures during boost or aggressive naturally aspirated tuning. Chevrolet Performance crankshafts undergo rigorous quality control and material selection, typically featuring nodular iron or forged steel construction with precision-ground journals and crank pins engineered to OEM specifications, ensuring compatibility with modern bearing sets and rod assemblies.

Engine builders and performance shops depend on Chevrolet Performance crankshafts for complete bottom-end assemblies, whether constructing LS-based Gen-5 LT mills for truck applications, performance crate engines, or custom builds. This component is essential when boring an engine, upgrading displacement on existing blocks, or assembling a complete short-block package for installation in hot rods, muscle cars, or modern performance platforms. Proper installation requires compatible pistons, connecting rods, and bearings matched to this 3.622-inch stroke specification, along with thorough balancing and honing to factory tolerances for optimal reliability and engine longevity.
