This set includes 16 lifters, featuring a standard 0.842-inch outside diameter and no offset.
Show original supplier description
The Delphi X12499225-16 is a full set of 16 hydraulic roller lifters, commonly referred to as LS7 lifters. This set is designed to be compatible with a wide range of V8 applications, including SBC and LT1 engines that were originally equipped with hydraulic roller lifters. These lifters are also a popular choice for AFM/DOD delete applications. Each lifter features a hydraulic roller design with a .842" diameter and a no-link bar construction. The set is sold as a complete package to ensure you have all the necessary components for your valvetrain upgrade. Installation recommendations include washing the lifters in an automotive solvent or mineral spirits to remove packing grease, checking rollers for binding, and then soaking in oil. A recommended preload of .060" - .080" is advised. It is crucial to use new, factory-type lifter trays during installation.
