LS7 Hydraulic Lifter Set

The Brian Tooley Racing Delphi Hydraulic LS7 Lifter Set X12499225-16 offers a comprehensive solution for refreshing or upgrading your LS engine's valvetrain. This complete set includes 16 Delphi hydraulic roller lifters, often referred to as LS7 lifters, meticulously packaged by Brian Tooley Racing (BTR) for LS engine builders and enthusiasts. They are compatible with GM LS engines from 1997 to 2013, covering displacements such as 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, and 7.0L. Specific LS engine codes like LS1, LS2, LS3, LS6, LS7, LQ4, LQ9, LM7, LY5, and LY6 can benefit from this upgrade. Beyond the core LS applications, these lifters also offer versatility by working in compatible Small Block Chevrolet (SBC) and Gen 2 LT1 engines that were originally equipped with hydraulic roller lifters. This broad compatibility makes them a flexible choice for various GM performance engine platforms. It is recommended to inspect lifters for any signs of damage upon receipt. Before installation, clean the lifters using an automotive solvent tank or mineral spirits to remove packing grease, ensuring proper oiling and smooth operation. Always check the roller movement for binding or roughness before installation. New factory-style lifter guide trays are also highly recommended for optimal performance and longevity.
