COMP Cams Evolution Retro-Fit Hydraulic Roller Lifters for Ford 289-351W - Set of 16

If you're rebuilding the top end of your Ford 289-351W engine, choosing the right lifters is crucial for performance and longevity. These COMP Cams Evolution Retro-Fit Hydraulic Roller Lifters are designed to provide a significant upgrade over stock components, especially for builds that demand consistent operation and quiet running.

What sets these lifters apart is their patented Hydraulic Cartridge Technology (HCT). This advanced design features a self-contained hydraulic cartridge that works with a reduced oil volume. This setup is less affected by oil aeration, leading to more consistent bleed rates across all lifters in the set. The smaller volume within the cartridge also contributes to a responsive and quiet lifter, greatly reducing startup noise. You can expect excellent performance at higher RPMs thanks to a precision-controlled bleed-down rate. The lifter body itself is incredibly stiff, minimizing distortion and further ensuring reliable hydraulic performance.

This isn't just a simple replacement part; it's a bespoke design built from the ground up to meet high-performance and durability needs. A notable feature is that the hydraulic element is serviceable, meaning you can rebuild these lifters yourself if needed. This set includes 16 lifters, enough for a complete engine rebuild.
