Key Features & Benefits
- Full Set of 16 Delphi Hydraulic Roller Lifters: Includes a complete V8 set of Delphi hydraulic roller lifters, giving you the correct quantity for a full LS valvetrain refresh. This makes the set ideal for camshaft installs, engine rebuilds, replacing worn lifters, or upgrading during top-end service.
- Commonly Known as LS7 Lifters: These Delphi hydraulic roller lifters are widely used in LS performance builds because of their proven factory-style design and broad compatibility. They are a popular choice for street cars, truck builds, swap projects, and performance engines that need dependable lifter operation.
- BTR Packaged for LS Builders: Packaged by Brian Tooley Racing, this lifter set is geared toward LS enthusiasts, engine builders, and performance shops looking for a trusted valvetrain replacement. BTR is well known in the LS market, making this a strong option for serious cam swap and rebuild projects.
- Great for Cam Swaps & Rebuilds: Replacing lifters during a camshaft upgrade or engine refresh helps support proper valve motion, quieter operation, and better long-term valvetrain reliability. Starting with fresh lifters is a smart move when servicing the top end of an LS engine.
- Hydraulic Roller Application Support: In addition to GM LS applications, these lifters can also work in compatible SBC and Gen 2 LT1 engines originally equipped with hydraulic roller lifters. This gives builders a flexible lifter option across multiple GM performance engine platforms.
BTR Delphi LS7 Lifter Cleaning Procedure
- Inspect Before Cleaning: After receiving your new LS7 lifters, remove them from the packaging and inspect each lifter for any obvious signs of damage to the lifter body or roller wheel. This step helps catch shipping or handling issues before installation.
- Remove Assembly Grease: Wash the lifters in an automotive solvent tank or with mineral spirits to help remove the stiff packing grease used during lifter assembly. Cleaning the lifters before installation helps promote proper oiling and smoother operation during startup.
- Check Roller Movement: After cleaning, inspect the roller wheels for any binding, roughness, or inconsistent movement before soaking and installation. Any lifter with questionable roller movement should be reviewed before being installed into the engine.
