What is the main benefit of using hydraulic roller lifters over flat tappet lifters?

Hydraulic roller lifters significantly decrease friction within the valvetrain. This leads to increased longevity for your engine components and allows for the use of more aggressive camshaft profiles than flat tappet lifters can support.

Do these lifters come with the necessary hardware for installation?

This set includes the OE-style hydraulic roller lifters. It's recommended to consult the manufacturer's installation instructions for a complete list of any additional components or hardware that may be required for your specific engine build.

What are the specific dimensions of these lifters?

These lifters have a standard .842" diameter and a seat height of 2.66". They weigh approximately 122 grams each.

Product Details

If you're working on a 1987 or newer Chevrolet Small Block, LT, or LS engine that came with factory roller lifters, these OE-Style Hydraulic Roller Lifters from COMP Cams are a solid option. They're designed as a direct replacement for your stock roller lifters, offering a straightforward upgrade path for your engine's valvetrain.

Compared to older flat tappet designs, these roller lifters significantly decrease friction. This not only helps increase the longevity of your engine components but also allows you to run more aggressive camshaft profiles without the same wear concerns. They feature a standard .842" diameter and a 2.66" seat height, making them a drop-in fit for many applications originally equipped with roller cams. The lack of a link bar means they function independently, simplifying installation in many factory roller setups.

This set is built to handle the demands of performance replacements and is suitable for a wide range of GM vehicles from the late 80s through newer models, including popular choices like the Chevrolet Camaro, Corvette, and various truck and SUV platforms.
