What is the purpose of the oil-restricting holes in these pushrods?

The smaller 0.050" oil holes help to control and limit the amount of oil flowing to the upper valvetrain components. This can be useful in certain engine builds to prevent excessive oiling and maintain precise valvetrain geometry.

What material are these pushrods made from and why is it important?

These pushrods are made from a single piece of 4130 chromemoly steel. This material is heat-treated and has a 0.080" wall thickness, making them strong and durable enough to withstand the stresses of engine operation.

How do I know if I need this specific length of pushrod?

Pushrod length is critical for proper valvetrain geometry and depends on your specific engine build, including camshaft, cylinder heads, and lifters. It's recommended to measure or consult your engine builder or service manual to determine the correct length for your application.

Product Details

If you're rebuilding the top end of your engine or looking to fine-tune your valvetrain, these COMP Cams Hi-Tech Oil Restricting pushrods are a solid option. They're designed to work with a wide range of vehicles, from classic Chevrolet Camaros and Corvettes to more modern Chevrolet C1500 trucks and Buick Regals from the early 80s. These pushrods play a crucial role in transferring the motion from your camshaft to your valves, ensuring proper engine timing and operation.

What sets these apart is the oil-restricting feature. They have smaller, 0.050-inch oil holes at the ends, which helps control oil flow to the valvetrain. This can be beneficial in certain builds to prevent over-oiling and maintain consistent valvetrain geometry. They're constructed from a single piece of 4130 chromemoly steel, heat-treated for durability, and feature a substantial 0.080-inch wall thickness. This well-built construction ensures they can handle the stresses of engine operation. Each pushrod is clearly marked with its length and diameter, making installation straightforward.

COMP Cams offers these in various lengths for different engine platforms, so you can find the right fit for your specific application. Having the correct pushrod length is critical for proper valvetrain geometry and performance.
