Key Features & Benefits

Delphi LS7 Hydraulic Roller Design: This single Delphi LS7-style lifter is designed for smooth hydraulic roller operation in compatible GM LS applications. It is a commonly used replacement lifter for stock rebuilds, camshaft swaps, and performance LS engine combinations.
Single Lifter Replacement: Sold individually, making it a practical choice when replacing one damaged or worn lifter instead of purchasing a complete set. This is helpful for targeted repairs, diagnostic replacements, or stocking individual service parts.
Broad GM LS Compatibility: Fits a wide range of GM LS engines including 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, and 7.0L platforms. This makes it a versatile lifter option for many LS-based cars, trucks, swaps, and performance builds.
Great for Camshaft & Valvetrain Service: Replacing worn lifters during camshaft work or engine repairs helps support proper valvetrain operation and long-term reliability. A properly functioning lifter is critical for quiet operation, consistent valve motion, and dependable engine performance.
Hydraulic Roller Application Support: Also works in compatible SBC, LS1, and LT1 applications that originally came with hydraulic roller lifters. This gives engine builders another proven option for hydraulic roller lifter service across multiple GM performance platforms.
