COMP Cams Ultra Pro Magnum XD Roller Rocker Arm, 1.5 Ratio, 7/16" Stud Diameter for Small Block Chevrolet, Single Piece.

The next design evolution of the Hi-Tech Stainless Steel Roller Rocker Arms are built to outlast and outperform in accuracy and strength. The Ultra Pro Magnum XD Rocker Arms are engineered from durable 8650 steel and include a machined billet pushrod seat insert for a wide range of super accurate ratios. A unique and wide ratio range to fit almost any popular application. These XD rockers are fully rebuildable and boast precision-sorted needle bearings and hardened roller tips. And they work with most diameter springs and retainers. The new XD design utilizes advanced FEA and CAD design and development to improve strength, stiffness and MOI optimization for drag and circle track applications.

  • Machined billet pushrod seat insert for wide range of rocker ratios used in popular Chevy and Ford applications
  • 8650 Steel construction outlasts and outperforms other rockers in accuracy and strength
  • For applications with up to 1000 lbs. open spring pressure
  • Precision-sorted needle bearings and hardened roller tips better distribute the load and reduce wear
  • Engineered for use in circle track and drag race applications
