85016 High Energy Hydraulic Roller Lifters

Hydraulic roller lifters decrease friction and increase longevity when directly compared to flat tappet lifters. They also accept much more aggressive cam profiles than flat tappet lifters allow. Hydraulic roller lifters are perfect performance replacements for stock hydraulic roller lifters or retro-fit hydraulic roller lifters for non-roller blocks.
