LS7-Style Hydraulic Roller Lifter

The Delphi LS7-style hydraulic roller lifters are precision-engineered for a wide range of GM LS V8 applications, including LS1, LS2, LS3, LS6, LS7, and truck engines like the 4.8L, 5.3L, 6.0L, and 6.2L. These lifters are a popular choice for engine builds, camshaft upgrades, AFM/DOD conversions, and complete valvetrain overhauls. Each lifter incorporates Delphi's signature gold-ring plunger design, ensuring consistent oil control and reliable hydraulic roller operation. Manufactured to OE-style specifications, they offer dependable performance for naturally aspirated, boosted, street, and mild performance applications. These lifters are a direct-fit replacement when installed correctly and cleaned according to the recommended procedure. While these lifters are designed for broad compatibility, it is essential to follow the Delphi LS7 Lifter Cleaning & Installation Procedure for optimal performance and longevity. Guide trays are not included with this set and are recommended for installation. Note that Delphi does not provide a manufacturer warranty on these lifters.
