Ev Hyd Roller Lifter Set SBC Retro Fit

The COMP Cams Evolution Hydraulic Roller Lifter Set SBC Retro Fit (Part No. 85301-16) is a complete 16-lifter set engineered to retrofit small block Chevy engines with modern hydraulic roller technology. This set delivers the precision valve actuation required for reliable performance across a wide range of engine builds, from stock restoration to high-performance street and race applications. The 0.842-inch outside diameter lifters are designed with link-bar construction for superior stability and consistent oil delivery under demanding operating conditions.

Hydraulic roller lifters offer significant advantages over solid lifter designs. The internal hydraulic load-bearing mechanism automatically adjusts to maintain proper valve clearance throughout the operating range, eliminating manual adjustment and reducing the risk of valve float at elevated RPM. The link-bar design in this COMP Cams set provides superior alignment and reduces lateral loads on the camshaft, extending component life and enabling more aggressive cam profiles. The 0.842-inch OD size is compatible with standard small block Chevy valve train geometry, allowing seamless integration into existing engine blocks without modification to lifter bores.

This retrofit set is ideal for builders restoring vintage SBC engines or upgrading older engines to more modern hydraulic roller technology. The complete 16-lifter count covers the full valve actuation system of a small block Chevy engine. COMP Cams holds a long-standing reputation in the camshaft and valvetrain market, and their Evolution series represents a proven balance of performance, reliability, and value. The set arrives ready to install with all components needed for a complete lifter replacement or retrofit upgrade.
