What makes these lifters quieter than others?

The Evolution HCT lifters use a patented design with a smaller internal hydraulic cartridge. This reduced volume and controlled bleed-down rate minimize startup noise and contribute to overall quieter operation, even at high RPM.

Can I rebuild these lifters myself?

Yes, a unique feature of these patented HCT lifters is that the hydraulic element is serviceable. This allows you to rebuild them in your own garage if needed, extending their lifespan and maintaining performance.

What is the benefit of the 'stiff lifter body' design?

A stiffer lifter body helps to greatly reduce distortion under load. This ensures that the hydraulic performance remains consistent and accurate, which is critical for maintaining precise valve timing in high-performance engines.

Product Details

If you're building or rebuilding a classic Oldsmobile or Pontiac V8, these COMP Cams Evolution HCT Retrofit Roller Lifters are a solid choice for achieving consistent performance and quiet operation. They're designed to work with your existing hydraulic roller camshaft setup, offering an improved solution over stock components for high-performance applications.

What sets these lifters apart is their patented Hydraulic Cartridge Technology (HCT). This design uses a self-contained hydraulic cartridge with a reduced oil volume, making it less susceptible to oil aeration. This means you get more consistent bleed rates between each lifter, which is crucial for maintaining precise valve timing, especially at higher RPMs. The smaller internal volume also contributes to a quieter lifter operation, reducing startup noise and ensuring excellent performance when you're pushing the engine hard. The lifter body itself is incredibly stiff, minimizing distortion and further enhancing the consistent hydraulic performance you're looking for.

These aren't just a simple replacement part; they're a bespoke design built from the ground up for demanding performance and durability. A notable feature is that the hydraulic element is serviceable, meaning you can rebuild them yourself if needed. This set includes 16 lifters, enough for a complete V8 engine.
