What makes these lifters quieter than others?

The smaller volume within the hydraulic cartridge and a precision-controlled bleed down rate contribute to quieter operation. This design greatly reduces startup noise and ensures consistent hydraulic performance.

Can these lifters be rebuilt?

Yes, the hydraulic element of these patented lifters is serviceable. This allows you to rebuild them in your own garage, which is an industry first.

What is the benefit of the stiff lifter body?

The patented cartridge design creates an incredibly stiff lifter body. This minimizes body distortion, which further ensures consistent hydraulic performance and durability.

Product Details

COMP Cams is known for making performance valvetrain components, and their Evolution Retro-Fit Hydraulic Roller Lifters are a prime example of that focus. These lifters are designed for Ford 289 and 351 Windsor engines, offering a significant upgrade over stock. They use a patented Hydraulic Cartridge Technology (HCT) that keeps oil volume consistent, leading to more reliable performance across the board.

What this means for your engine is a more predictable bleed-down rate, which translates to quieter startup and excellent performance even at high RPMs. The smaller internal cartridge also contributes to a very responsive and quiet lifter. COMP Cams also built these with a stiff lifter body to reduce distortion, further ensuring that hydraulic performance stays consistent. This isn't just a simple replacement part; it's a bespoke design built from the ground up for demanding performance and durability. Plus, the hydraulic element is serviceable, meaning you can rebuild them yourself if needed.
