Show original supplier description
The Delphi LS7 hydraulic roller lifter is offered individually and is designed for V8 applications, commonly referred to as LS7 lifters. Beyond LS engines, these lifters are also suitable for SBC and LT1 applications that originally came equipped with hydraulic roller lifters, and a variety of Gen III, IV, and V GM V8 engine platforms. Constructed with a .842" diameter and a no-link bar design, these lifters are engineered for performance and reliability. The product information includes specifications such as engine type (Gen III/Gen IV LS), brand (Delphi), part type (Lifter), lifter style (HYDRAULIC ROLLER), and quantity (SOLD INDIVIDUALLY). Installation recommendations include cleaning the lifters with an automotive solvent or mineral spirits to remove packing grease, and checking rollers for binding before soaking them in oil. A recommended preload of .060" to .080" is specified. It is also strongly advised to use new, factory-type lifter trays when installing these lifters.
