Crankshaft Sprocket - LS

The Crankshaft Sprocket for LS-Series engines from Chevrolet Performance is a vital OEM-specification timing component designed for builders and mechanics who are upgrading or maintaining high-performance LS platforms. This sprocket is essential for driving the camshaft timing chain and synchronizing valve operation with crankshaft rotation, which directly impacts engine efficiency and power delivery.

Manufactured to OEM tolerances, the Crankshaft Sprocket LS is designed to ensure factory-correct timing geometry and durability. It features a tooth profile and bore diameter that are precisely matched to factory crankshaft geometry, which helps eliminate timing slack and maintain consistent valve overlap. This is crucial for maximizing combustion efficiency and preventing detonation, especially in forced-induction applications.

Engine builders, vintage hot rod fabricators, and performance technicians can rely on this genuine Chevrolet Performance part when replacing components during engine teardowns or upgrading from earlier-generation blocks. Installation requires removing the timing cover and chain tensioner, making it a straightforward task for those familiar with LS engine builds.
