LS & LSX Engine Components

Factory-Engineered LS Performance Parts

It’s simple: No one knows more about LS performance than Chevrolet Performance and no one comes close to matching our range of performance parts – all engineered at the factory for the best performance and production-quality fit.

From the throttle body to the oil pan, including production-based blocks, heads, cams and more – as well as the growing portfolio of LSX maximum-performance parts, we've got you covered.

Chevrolet Performance even offers intake manifolds and ignition kits for swapping out production-style fuel injection for carbureted aspiration – just the thing for a more traditional look under the hood of a vintage car or to conform to certain racing rules.

Whether you’re building a quick, late-model performer for the strip or road course, or dropping an LS engine into your vintage muscle car or classic truck, Chevrolet Performance is your source for factory-engineered parts that perform like no others.
