Info

COMP Cams Ultra Pro Magnum Roller Rocker Arms, 1.8 Ratio, Pedestal Mount, LS3, Set of 16.

Utilizing years of Valvetrain design experience, the latest FEA stress analysis technology, and an exhaustive testing regiment (Dyno and Spintron), the COMP Cams engineering team left no detail to chance. Everything from casting techniques to valve spring clearance was scrutinized to ensure that the new Ultra Pro Magnum rocker arms not only lived up to the lofty standards of their predecessor, but also took stud mount rocker performance, stability, and value to a whole new level.

  • Investment cast 8650 chromemoly body and arched, weblike design deliver increased strength and rigidity while reducing moment of inertia
  • Withstand valve spring pressures up to 850 lbs.
  • Unique black oxide exterior finish helps prevent corrosion, thus increasing durability
  • Increased retainer and valve spring clearances allow use of large diameter springs, retainers and +.050" locks without clearance or fitment issues
  • Feature oversized trunnions, precision-sorted needle bearings and hardened roller tips
