What makes these lifters 'retro-fit'?

These are retro-fit lifters because they are designed to work in factory LS-based engine blocks that originally came with hydraulic roller lifters, allowing for an upgrade or replacement without needing to modify the block itself.

What is the benefit of a 'short travel' lifter?

A short travel design means the lifter has less internal movement. This allows for a lighter pre-load on the valvetrain and reduced oil flow, which is beneficial for engines that operate at very high RPMs.

Do these lifters come as a pair or a set?

The product listing indicates these are a lifter pair, meaning they are sold as two lifters. For a complete engine build, you would typically need to purchase multiple pairs depending on the engine's cylinder count.

Product Details

COMP Cams is well-known for performance valvetrain components, and these LS1 Retro-Fit Hydraulic Roller Lifters are a prime example of their focus on high-revving applications. If you're building or rebuilding an LS-based engine, whether it's a factory GM LS, an LSX, an RHS, or a Warhawk, these lifters are designed to handle the demands of increased RPMs. They feature a short travel design, which allows for lighter pre-load and reduced oiling. This makes them a popular choice for the highest-revving lifter option available for these popular GM engine platforms.

The short travel design is key here. It means less movement within the lifter itself, which translates to more consistent valve control at high engine speeds. This reduced oiling also helps prevent excessive oil flow that can sometimes hinder performance in extreme RPM situations. These lifters are built to be a direct replacement for many GM LS, LSX, RHS, and Warhawk engines, making installation straightforward for those familiar with LS engine builds.
