COMP Cams Ultra Pro Mag Rockers Chrysler

When you're rebuilding the top end of your Chrysler LA small block engine, you want components that can handle the demands of higher spring rates and roller lobes. This Ultra Pro Magnum shaft-mount rocker arm kit from COMP Cams is designed to do just that. It includes everything you need to get started: the rocker arms themselves, along with the necessary shafts and spacers, all secured with bolts. This kit is specifically made for Chrysler LA engines ranging from 273 to 360 cubic inches, covering a wide array of popular Mopar vehicles from the 1950s through the 1980s, like the Dodge Dart, Plymouth Barracuda, and Chrysler Cordoba.

These rocker arms are constructed from SAE 8620 chromemoly steel, a well-built material chosen for its strength and stiffness, and then heat-treated to ensure they hold up under stress. They feature proprietary bushing inserts and a unique oiling system that circulates oil to all critical pivot points, promoting long service life. The 1.5 ratio is a common choice for improving valve lift without excessive stress on other valvetrain components. A notable feature is the special adjuster that allows you to use conventional ball-end pushrods, simplifying installation and compatibility with many existing pushrod sets.

COMP Cams also offers these rocker arms in kits that include Hi-Tech pushrods, available for both hydraulic flat tappet and solid flat tappet lifter applications, if you're looking for a complete valvetrain solution. This kit is a solid option for anyone looking to enhance their engine's performance and reliability with a robust set of rocker arms.
