The Ultra Pro Magnum™ Roller Rocker Arms not only uphold the esteemed standards of the original Pro Magnums™ but also elevate stud mount rocker performance, stability, and value. Crafted from 8650 chromemoly material with an arched, web-like design, these rocker arms provide heightened strength and rigidity while concurrently reducing the moment of inertia and optimizing dynamic balance. The distinctive black oxide exterior finish serves to prevent corrosion, enhancing overall durability. Featuring oversized trunions, precision-sorted needle bearings, and hardened roller tips, these rocker arms are engineered for peak performance and dependability. Optimized retainer and valve spring clearances ensure compatibility with most diameter springs, retainers, and +.050" locks without any clearance or fitment issues.
