COMP Cams Hydraulic Flt Tappet Lifters Ch

COMP Cams is well-known for making performance valvetrain components, and these Race Hydraulic Flat Lifters are a prime example of their commitment to the racing world. If you're building a Chevrolet Small or Big Block engine for serious competition, these lifters are designed to handle the demands of high-RPM operation and sustained stress. They feature tighter plunger-to-body tolerances than standard lifters, which helps optimize performance and consistency under pressure. You'll also find premium one-piece pushrod seats, adding to their overall strength and reliability.

What really sets these apart for race use is the extra heavy-duty snap ring design. This beefed-up construction increases the lifter's strength and durability, giving you more confidence when you're pushing your engine hard. The manufacturer notes that pre-load can be set between .000" and .030", with a recommended setting of .000". An additional .030" can be used to help with tuning or to address any potential lifter noise that might arise with the .000" setting. These lifters have a standard .842" diameter, a weight of 104g, and a seat height of 2.01".
