    The next design evolution of Hi-Tech Stainless Steel Roller Rocker Arms is built to outlast and outperform in accuracy and strength. Ultra Pro Magnum XD Rocker Arms are engineered from durable 8650 steel and have a machined billet pushrod seat insert for super accurate ratios. A unique and wide ratio range is available to fit almost any popular application from 1.5 to 1.73 in .5 increments for Chevy and 1.6 to 1.73 for Ford. These XD Rockers are 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 development to improve strength, stiffness, and MOI optimization for drag and circle track applications.

    Features
  • 8650 steel construction outlasts and outperforms other rockers in accuracy and strength
  • Machined billet pushrod seat insert for a wide range of rocker ratios used in popular Chevy and Ford applications
  • Precision-sorted needle bearings better distribute the load and reduce wear for longer service life
  • Engineered for use in endurance, circle track, and drag race applications with improved strength and durability
