SBC Hi-Tech Roller Lifter

The COMP Cams SBC Hi-Tech Roller Lifter (part number 818-1) is a mechanical roller lifter engineered for small block Chevy and GM V6 engines seeking reliable valve actuation with roller technology. This lifter features a 0.842-inch outside diameter and link bar design, delivering the precision needed for high-performance and street engine builds where consistent cam lobe tracking and reduced friction are priorities.

As a mechanical roller lifter, this component eliminates the flat-face design common in hydraulic lifters, instead using a rolling element that maintains contact with the camshaft lobe. The link bar configuration ensures proper alignment and stability during operation, critical for engines running aggressive cam profiles or extended RPM ranges. At 0.27 lbs and compact dimensions of 2.1 x 1 x 4.25 inches, the lifter integrates seamlessly into existing small block Chevy and V6 engine bays without adding unnecessary weight or requiring frame modifications. COMP Cams' Endure-X construction is designed to handle the demands of both street and competition environments.

This lifter is suited for builders and enthusiasts restoring or upgrading small block Chevy and GM V6 engines who require a mechanical roller solution. Whether you're assembling a street performance engine, preparing for track use, or restoring a classic platform, the SBC Hi-Tech Roller Lifter addresses the need for durable, precision valve train components. Installation requires correct camshaft matching and proper engine assembly procedures to ensure optimal performance and longevity. This is a single lifter; complete valve train assemblies will require matched sets.

COMP Cams has established a strong reputation in the performance engine community for precision manufacturing and rigorous testing of valve train components. Mechanical roller lifters represent the evolution of small block engine technology, offering advantages in consistency and reduced wear compared to flat-tappet alternatives when paired with compatible camshafts and proper valve train geometry.
