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.
