This COMP Cams rocker shaft is designed to provide clearance for valve springs that are 1.550 inches in diameter or larger. It helps avoid interference issues with these bigger springs.

Does this rocker shaft come with any hardware or other components?

Product Details

When you're rebuilding the top end of your Chrysler small block engine, especially if you're fitting larger diameter valve springs like 1.550 inches or more, you might run into clearance issues with your rocker arms. Instead of modifying your new rocker arms, this offset rocker shaft from COMP Cams offers a clean solution.

This shaft is designed with a .100 inch offset. What that means in practice is it shifts your rocker arms inboard, creating the necessary clearance between the rocker arm and the valve spring. This is a well-built component that helps ensure your valvetrain components work together smoothly without interference, especially when you're pushing the limits with bigger springs. It's a smart way to avoid cutting into your rocker arms and potentially weakening them.

This offset rocker shaft fits a wide range of Chrysler small block engines from the 273 up to the 360 cubic inch displacement. It's a popular choice for builds in vehicles like the Dodge Challenger, Plymouth Barracuda, and various Chrysler and Dodge trucks from the 1960s and 70s.
