GM Performance LS7 Hydraulic Roller Lifters – Set of 16 | LS1 LS2 LS3

Upgrade or refresh the valvetrain in your LS-powered vehicle with a genuine set of GM Performance LS7 Hydraulic Roller Lifters.

Originally fitted to the LS7 7.0L performance engine, these lifters have become a popular upgrade and replacement option for earlier LS engines thanks to their improved internal valving and suitability for higher-RPM performance applications.

Supplied as a complete set of 16 genuine GM lifters, they are ideal for replacing worn, noisy or failed factory lifters during an engine refresh, camshaft upgrade or performance build.

Features

  • Genuine GM Performance LS7 hydraulic roller lifters

  • Complete set of 16 lifters

  • Improved valving compared with earlier LS lifter designs

  • Suitable for performance and higher-RPM applications

  • Direct replacement for many non-AFM LS engines

  • Uses factory-style LS lifter guides and retainers

  • 0.842" outside diameter

  • Ideal for camshaft upgrades, engine rebuilds and preventative valvetrain maintenance

Vehicle / Engine Compatibility

Suitable for applications including:

  • Holden / GM LS1

  • Holden / GM LS2

  • Holden / GM LS3

  • Other compatible non-AFM LS-based engines

  • L76 / L77 / L99 applications when used as part of a complete AFM/DOD delete conversion

  • Compatible Gen V LT applications where AFM/DOD has been correctly deleted

Important Fitment Information

These are LS7-spec lifters, but they are not limited to LS7 engines.

LS7 lifters are commonly used as an upgraded replacement for earlier LS-series hydraulic roller lifters and are suitable for a broad range of LS performance builds.

For engines originally equipped with AFM/DOD, these lifters are not a direct replacement for the factory AFM lifters unless the engine is being converted using the appropriate complete AFM/DOD delete components.

We recommend replacing the lifter trays/guides when installing new lifters, particularly on higher-mileage engines or during a camshaft replacement.
