COMP Cams Chevrolet Small Block XD Short Travel Retro-Fit Hydraulic Roller Lifter Set

COMP Cams is well-known for performance valvetrain components, and their XD Short Travel Retro-Fit Hydraulic Roller Lifters are a prime example of that expertise for Chevrolet Small Block engines. These lifters are designed to give you the best of both worlds: the quick recovery of a light lifter pre-load and the increased stiffness that comes from reduced oil volume under the plunger. This combination helps create a more stable valvetrain that can handle higher RPMs, making them a solid choice for demanding builds.

What sets these XD (Xtreme Duty) lifters apart is the inclusion of a heavy-duty tool steel pushrod seat. This upgrade adds significant strength and durability, making them particularly well-suited for applications like turbo drag cars and offshore powerboats where the valvetrain is under extreme stress. The short travel design itself is key, allowing for precise control over lifter pre-load and oil flow, which directly contributes to their ability to operate reliably at high engine speeds. They are designed to fit a range of Chevrolet Small Block engines, including those found in vehicles like the Chevrolet Camaro, GMC C1500 Suburban, and Buick Roadmaster from the late 80s and early 90s.

When rebuilding or upgrading your valvetrain, especially for high-performance street or racing applications, these lifters offer a well-built solution. They are designed as a retro-fit, meaning they can be installed in older Small Block Chevy engines that didn't originally come with hydraulic roller lifters, providing a significant performance advantage. Ensure you follow the manufacturer's installation instructions carefully for proper pre-load settings to get the most out of their advanced design.
