• Replace：12499225 HL124. Compatible with Chevy 1992-2014,GMC 1992-2013, Buick 1988-2008,Cadillac 2002-2006,Hummer 2003-2007 ,Oldsmobile 1986-1999,Pontiac 1988-2006. For GM LS1, LS2, LS3, LS6, LS7, LS9 LSX engines (4.8, 5.3, 5.7, 6.0,6.2,7).
• Package Includes:16 Hydraulic roller lifters with 4 lifter guides.
• Function: Hydraulic lifters, also known as valve lifters or hydraulic lash adjusters, help eliminate the need for internal combustion engines to have mechanical clearance in the engine valve train to prevent the valve from remaining open and damaged as the valve train undergoes a thermal expansion process. Valve lifters keep valves healthy and reduce valve train noise from actuation to closure. Tight tolerance for low leak rates. Fast pumping and excellent high RPM performance.
• Quality: Tested to ensure leaks and tip oil flow are within specification. Same size as OE parts, rails hold the lifter tight for smooth operation. This is a good insurance to make sure you don't run into lift problems later on with cam load issues, especially if it's a motor pushing high horsepower.
• Note: Please confirm your part number is applicable before purchasing. Be sure to review the general cleanliness of the engine before installing the lift. Soak the lifter overnight in compound break-in oil, this will provide very good lubrication on the outside, fill up all the needle bearings, and you will remove most of the air from the plunger assembly. Take some simple precautions to keep dust and debris from entering your oil system during installation.
