COMP Cams Ultra Pro Mag Rocker Chrysler BB

COMP Cams is a well-known name when it comes to making your engine perform better. These Ultra Pro Magnum rocker arms are built for Chrysler 383-440 Big Block engines, offering improved strength and durability. They are designed to handle up to 850 lbs of open spring pressure, making them a solid choice for performance builds.

These rocker arms are constructed from investment cast 8650 chromemoly steel with an arched, web-like design. This construction not only increases strength and rigidity but also helps reduce the moment of inertia for better balance. The black oxide exterior finish helps prevent corrosion and adds to their durability. You'll also find oversized trunnions, precision-sorted needle bearings, and hardened roller tips for reliable performance and dependability. The design also accounts for retainer and valve spring clearances, allowing for use with most common spring diameters and locks without issues.

This particular part number is for the right-side shaft-mount rocker arm, intended for use with Chrysler 383-440 B/RB engines. They are designed to work with ball/ball style pushrods and come with a lifetime warranty on the rocker bodies against breakage.
