What is the main benefit of oil restricting pushrods?

Oil restricting pushrods help to control the amount of oil that flows to the top end of your valvetrain. This can be beneficial for engines where precise oil management is needed, helping to prevent issues like excessive oil splashing or pressure loss in the rocker arms.

What material are these pushrods made from?

These COMP Cams Hi-Tech pushrods are made from a single piece of 4130 chromemoly steel. They are heat-treated for added durability and have a hardness rating of 60 Rockwell.

Are these pushrods suitable for all engine builds?

These pushrods are designed for a wide range of GM vehicles and are particularly useful when precise oil control in the valvetrain is desired. It's important to ensure the 7.800-inch length and 5/16-inch diameter are correct for your specific engine application.

Product Details

If you're working on the valvetrain of a wide range of GM vehicles, these COMP Cams Hi-Tech Oil Restricting pushrods are a solid option. They're specifically designed to manage oil flow to the upper parts of your engine, which can be important for maintaining consistent lubrication and preventing issues like excessive oil consumption or pressure loss in the rocker arms.

These pushrods are built from a single piece of 4130 chromemoly steel, heat-treated for durability, and feature a wall thickness of .080 inches. What sets these apart is the oil hole size on the ends, which are a smaller .050 inches compared to standard Hi-Tech pushrods. This reduced size helps to restrict oil flow, giving you more control over how much oil reaches the rocker arms and valve springs. Each pushrod is clearly marked with its length and diameter, making installation straightforward, especially when you need to confirm you have the correct length for your specific engine setup.

This set is designed to fit a broad spectrum of vehicles, including popular models like the Chevrolet Camaro, Corvette, and various C/K series trucks from the 1980s and 1990s. Having the right pushrod length is crucial for proper valvetrain geometry, so COMP Cams offers multiple lengths to help you dial in your engine's performance.
