Chevrolet Performance Parts

Chevrolet Performance Crate Engines, Transmissions & GM-Engineered Performance Parts

Chevrolet Performance is the only performance parts brand that comes directly from the factory that built the engine. As GM's official performance division, Chevrolet Performance engineers, tests, and warrants crate engines, transmissions, superchargers, and performance components to the same standards as production vehicle powertrains — because they're built by the same engineers, on the same equipment, with the same quality controls. If you're building a GM-powered vehicle and want factory-backed performance, this is the source.

Crate Engines

Chevrolet Performance's crate engine lineup spans the full range of GM performance architecture — from classic small block and big block Chevy engines for restoration and restomod builds to the latest LS and LT-series engines that represent the current state of GM performance engineering. Every Chevrolet Performance crate engine is assembled, tested, and certified at GM facilities and backed by a GM warranty — the only crate engine on the market with that level of factory support.

The LS lineup includes the LS3, LS376, and LSX series — ranging from 430 to 580+ horsepower in naturally aspirated configuration. The LT lineup brings direct injection and Active Fuel Management technology to crate engine applications, with the LT1, LT4, and supercharged LT5 delivering up to 755 horsepower in factory-warranted form. For classic builds, the ZZ series small blocks and big block 454 and 502 crate engines provide modern reliability in traditional displacement packages.

Superchargers & Forced Induction

Chevrolet Performance's supercharger systems are factory-engineered for specific LS and LT engine applications, delivering the integration and reliability that comes from being designed by the same team that built the engine. Their Magnuson-sourced supercharger systems are calibrated for the specific airflow and fuel delivery characteristics of each engine, eliminating the tuning uncertainty that comes with adapting third-party forced induction to a factory engine.

Transmissions & Drivetrain

Chevrolet Performance's transmission lineup includes the T56 Magnum six-speed manual, the 4L80-E and 6L80-E automatics, and the TR6060 — factory-engineered units rated for the torque output of Chevrolet Performance crate engines. Matching a Chevrolet Performance engine with a Chevrolet Performance transmission ensures correct torque capacity, bellhousing compatibility, and calibration without the adaptation issues that arise from mixing brands.

Performance Components & Accessories

Beyond complete engines and transmissions, Chevrolet Performance offers a comprehensive range of performance components — camshafts, cylinder heads, intake manifolds, fuel injectors, ignition components, and engine dress-up accessories engineered specifically for LS and LT applications. These are the same components used in GM's factory performance vehicles, available individually for builders upgrading existing engines or building custom combinations.
