COMP Cams Rocker Arm CS 1.52 3/8 Ultra P

If you're working on a Chevrolet V6 or Small Block V8 engine from 1988 and later, these COMP Cams Ultra Pro Magnum rocker arms are a solid option for your build. They're designed to handle up to 850 pounds of open spring pressure, making them suitable for many performance applications. The 1.52 ratio helps optimize valve lift and duration, contributing to better engine breathing.

These rocker arms are constructed from investment-cast 8650 chromemoly steel, which is known for its strength and rigidity. COMP Cams gives them a black oxide exterior finish to help prevent corrosion and increase overall durability. You'll also find oversized trunions, precision-sorted needle bearings, and hardened roller tips, all working together to ensure smooth operation and long-term dependability. The design also pays attention to retainer and valve spring clearances, allowing for compatibility with most common spring diameters and locks without fitment issues.

This particular set is for engines using a 3/8-inch stud size and features self-aligning capabilities, which can simplify installation on many Chevrolet engines, including popular models like the Camaro, Corvette, and various truck and van applications from the late 80s through the mid-2000s.
