What is the main benefit of using hydraulic roller lifters over flat tappet lifters?

Hydraulic roller lifters generally offer reduced friction compared to flat tappet designs. This can lead to improved valvetrain durability and potentially allow for faster 'pump up' for more consistent oil pressure.

What material are the axles made from, and why is that important?

The axles are made from heat-treated 52100 steel. This is a strong and wear-resistant material, crucial for handling the increased loads and stresses associated with a roller valvetrain setup.

Does this set include everything needed to install the lifters?

This set includes 16 lifters, which is the complete quantity for a Chrysler small block engine. However, it does not include other components like pushrods or rocker arms, which may need to be compatible with the roller setup.

Product Details

COMP Cams is well-known for making performance engine parts, and their Retro-Fit Hydraulic Roller Lifter Set is a prime example of that expertise. If you're looking to upgrade your Chrysler small block engine, specifically the 273-360 cubic inch versions, these lifters are designed to help you get more out of your valvetrain. They allow you to switch from a flat tappet cam setup to a hydraulic roller setup, which can offer benefits like reduced friction and improved durability.

What sets these lifters apart is their patent-pending piston design. This feature allows trapped air to escape the lifter, which helps them 'pump up' faster. This means they can maintain consistent oil pressure to the valvetrain more reliably, especially during initial startup or under demanding conditions. The axles are made from heat-treated 52100 steel, a strong material known for its wear resistance, ensuring these lifters can handle the increased stress of a roller setup. They also feature a lightweight body design, which can help reduce overall valvetrain mass.

This set includes all 16 lifters needed for a complete engine build. They are designed with a precise piston fit to achieve the lowest possible leakdown rate, ensuring efficient operation. While these lifters are designed for a wide range of Chrysler, Dodge, and Plymouth vehicles from the late 60s through the early 80s, like the Dodge D150 or Chrysler Cordoba, it's always a good idea to double-check the specific fitment for your vehicle. This upgrade is a significant step towards a more efficient and robust engine build.
