COMP Cams Lifters LS1 Retro-Fit Short Travel Hydraulic Roller

If you're building a high-performance GM LS engine, especially one that will see hard use like in a turbo drag car or a serious street build, you need components that can handle the stress. These COMP Cams XD Retro-Fit Short Travel Hydraulic Roller Lifters are designed to give you the best of both worlds when it comes to lifter pre-load. Some engines perform better with a light pre-load for quicker recovery from valve train harmonics, while others benefit from a heavier pre-load that reduces oil volume under the plunger, making the lifter stiffer. These lifters let you achieve both, offering a stable and high-revving hydraulic lifter that's ideal for factory LS, RHS, LSX, and Warhawk blocks.

What sets the XD version apart is the inclusion of a heavy-duty tool steel pushrod seat. This upgrade adds significant strength and durability, making these lifters a solid choice for Xtreme Duty applications where reliability is paramount. The short travel design itself is key, allowing for precise control over pre-load and reduced oil volume, which contributes to increased lifter stiffness and the ability to rev higher with confidence. They are designed to fit a wide range of GM vehicles, including popular models like the Chevrolet Camaro, Cadillac Escalade, and Chevrolet Silverado.

When you're pushing your engine hard, every component matters. These lifters are built to be a strong link in your performance build. They are designed as a retro-fit, meaning they can be installed in place of your stock lifters to gain the benefits of this advanced design. Make sure to consult the manufacturer's installation instructions for proper pre-load settings specific to your engine build.
