What makes these lifters quieter than others?

The smaller volume within the hydraulic cartridge and the precision-controlled bleed down rate contribute to significantly reduced startup noise and overall quieter operation compared to many other hydraulic lifters on the market.

Can I rebuild these lifters myself?

Yes, as an industry first, the hydraulic element of these patented lifters is designed to be serviceable. This allows you to rebuild them in your own garage, maintaining their performance over time.

What is the main advantage of the HCT design?

The patented Hydraulic Cartridge Technology (HCT) provides the most consistent performance of any set of lifters in the aftermarket. It ensures consistent bleed rates and minimizes body distortion for reliable operation, especially at high RPMs.

Product Details

This set includes 16 COMP Cams Evolution Retro-Fit Hydraulic Roller Lifters, designed specifically for Chrysler 273-360 small block engines. These lifters are a significant upgrade over stock, featuring a patented Hydraulic Cartridge Technology (HCT) that sets them apart in the aftermarket. The HCT system uses a self-contained hydraulic cartridge with reduced oil volume, making it less susceptible to oil aeration and ensuring very consistent bleed rates between each lifter. This design contributes to exceptionally responsive and quiet operation, greatly reducing startup noise and providing excellent performance at high RPMs.

The unique cartridge design also results in an incredibly stiff lifter body, which minimizes distortion and further guarantees consistent hydraulic performance. This isn't just a replacement part; it's a completely new design built from the ground up to meet the high performance and durability demands of serious engine builds. A notable feature is that the hydraulic element of these patented lifters is serviceable, meaning you can rebuild them yourself in your garage, extending their lifespan and maintaining optimal performance over time.

If you're rebuilding the top end of your Chrysler small block and looking for the most consistent, highest performing, and quietest hydraulic lifter available, this set from COMP Cams is a solid option. Their advanced design aims to deliver reliability and responsiveness for demanding applications.
