Another COMP Cams lifter option is the redesigned Endure-X. While not as trick as the Elite Race lifters, these use EDM Oil Injection, which delivers pressurized oil to the needle bearings inside the roller. This single design feature greatly improves longevity compared to standard roller lifters. Another trick is to bore a Chevy block to accept larger-diameter lifters for a Ford. The stock Chevy diameter is 0.842 inch and the Ford diameter is 0.875. The COMP Cams lifter set (PN 823-16) is designed specifically for this. COMP offers a rebuild program for the Endure-X lifters, which replaces the axle and roller assembly and inspects the rest of the lifter body.
