COMP Cams Shaft Rocker CRS OEM Iron Hea

If you're rebuilding the top end of your Chrysler 273, 318, 360 engine, especially one destined for performance use, a shaft-mount rocker system like this one from COMP Cams is a smart move. This kit properly positions the rocker arm over the valve, which is key to efficiently transferring the camshaft's power to the valve. It's a direct way to get more usable power out of your engine.

What sets this system apart is its rigidity. Instead of individual stud-mounted rockers, these mount to a horizontal shaft. This shaft acts as the fulcrum, creating a much stiffer and more stable valve train. This added stability means less flex and better control, especially at higher RPMs. The rockers themselves are made from strong 2024 aluminum, and they ride on a hardened 8620 steel shaft. COMP Cams uses advanced computer technology in their design and backs it up with real-world testing in racing environments.

This specific kit is designed for Chrysler LA-series engines with OE iron heads that have shaft oiling. It includes 1.5 ratio rockers, which is a common and effective ratio for many performance builds. Having a stable and well-positioned rocker arm is crucial for consistent valve operation and maximizing the power your camshaft is designed to make.
