The Ultra Pro Magnum™ Roller Rocker Arms not only meet but exceed the high standards set by the original Pro Magnums™, elevating stud mount rocker performance, stability, and overall value. Crafted from 8650 chromemoly material with an arched, web-like design, these rocker arms provide increased strength and rigidity while simultaneously reducing the moment of inertia and optimizing dynamic balance. A distinctive black oxide exterior finish not only enhances corrosion resistance but also contributes to extended durability. With oversized trunions, precision-sorted needle bearings, and hardened roller tips, these rocker arms are engineered for exceptional 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.
