Ev Hyd Roller Lifter Set SBM Retro Fit

The COMP Cams Evolution Hydraulic Roller Lifter Set for Small Block Mopar is a complete 16-piece retrofit solution designed to modernize older Small Block Mopar engines with contemporary hydraulic roller lifter technology. This set delivers the precise valve event timing and reduced friction that hydraulic roller lifters provide, enabling engine builders and enthusiasts to enhance performance, durability, and reliability in classic Mopar powerplants without requiring a complete engine redesign.

Each lifter in this set features a 0.904-inch outer diameter, the standard bore specification for Small Block Mopar applications, ensuring direct fit compatibility with factory and most aftermarket Small Block Mopar cylinder blocks. The hydraulic roller design maintains automatic valve lash adjustment, eliminating the need for frequent manual adjustment while reducing wear on rocker arms and pushrods. The 16-piece count covers a full Small Block Mopar engine, making this an all-in-one retrofit solution. COMP Cams' reputation for precision manufacturing ensures consistent performance across all 16 lifters, critical for balanced valve events and engine longevity.

This retrofit set is ideal for builders restoring or upgrading Small Block Mopar engines—whether for street performance, marine applications, or vintage car restorations. Upgrading to hydraulic roller lifters from older flat-tappet designs reduces parasitic friction losses and extends component life, particularly valuable in high-mileage builds where reliability matters. The evolution line represents COMP Cams' commitment to providing modern hydraulic roller technology for engines originally equipped with inferior flat-tappet lifters, allowing Mopar enthusiasts to gain contemporary durability and performance without abandoning their classic powerplants.
