Product Details

The COMP Cams Ultra Pro Magnum Self-Aligning Roller Rocker Arm Set delivers professional-grade valvetrain performance for 1988 and later Chevrolet V6 engines. Engineered with investment cast 8650 chromoly steel construction, these rocker arms feature an arched, web-like design that provides a 29 percent increase in strength and rigidity while reducing moment of inertia and optimizing dynamic balance.

Key Features:

  • 1.52:1 rocker ratio for increased valve lift
  • 3/8" stud diameter for late model Chevy V6 applications
  • Self-aligning design ensures proper geometry and reduces side loading on valve stems
  • Investment cast 8650 chromoly steel construction withstands up to 850 lbs of spring pressure
  • Black oxide finish provides corrosion resistance and distinctive appearance
  • Oversized trunnion with precision-sorted needle bearings for high-load valve spring compatibility
  • Hardened roller tips reduce friction and eliminate premature valve guide wear
  • Enhanced valve spring clearances accommodate large-diameter springs, retainers, and locks
  • Full roller design maximizes lift and valvetrain control at high RPM

Developed using advanced FEA stress analysis and extensive dyno and Spintron testing, these rocker arms represent the next evolution in stud-mount rocker arm technology.

Seemed to work great just gotta wait and see when they get here.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
