COMP Cams Ultra Pro Mag Rocker Kit Chrysler 3

If you're working on a Chrysler 383, 400, or 440 big block engine, this COMP Cams Ultra Pro Magnum rocker arm kit is built to handle the demands of a performance build. This kit is designed for shaft-mounted applications and includes everything you need to get them installed, like bolts, shafts, and spacers. It's a well-built system that's made to last.

These rocker arms are constructed from investment cast 8620 chromemoly steel, which gives them a strong and rigid structure. The arched, web-like design helps reduce the moment of inertia, optimizing the balance of your valvetrain. They also feature a black oxide exterior finish to help prevent corrosion and increase overall durability. Inside, you'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips for reliable performance and dependability. The design also accounts for optimized retainer and valve spring clearances, meaning you can use most common spring diameters, retainers, and +.050" locks without running into clearance issues. This kit is rated to handle up to 850 lbs of open spring pressure, making it suitable for aggressive camshaft profiles.

This kit is a solid option for a wide range of Chrysler, Dodge, and Plymouth vehicles from the late 1950s through the late 1970s, including popular models like the Dodge Charger, Chrysler New Yorker, and Plymouth Barracuda. Remember, this kit requires ball-style pushrods for proper operation. COMP Cams backs these rocker bodies with a lifetime warranty against breakage, showing their confidence in the strength and durability of this product.
