LS Series Captured Link Bar Retro-Fit Roller Lifter for 1997-Present, Fits Both Factory & RHS®, LSX, Warhawk Blocks, Short Travel, Race Type
Designed to perform at higher engine speeds
When equipped with hydraulic lifters, high rpm is limited by improper position of lifter’s internal piston as lifter “pumps up”
Improper location results in open valves that lead to lost power and possibly engine failure
Minimize internal piston movement to allow higher engine rpm
These are coated, making the lifter size .002″ bigger than stock. Be careful on size of bore.
