  Forged Roller Rocker Arms

  • Forged from 8620 steel for greater strength
  • Designed using Finite Element Analysis (FEA)
  • Rollers eliminate thrusting on valves for decreased wear on the valve train
  • Rocker geometry is better suited to high lift cams
  • Larger surface area on the thrust surfaces reduces wear on the heads
  • Bushings are 50% longer than stock, increasing time between rebuilds
  • Compatible with stock or S&S CNC heads
  • Oil is sprayed directly on the valve springs, reducing potential for breaking a valve due to over-heating (stock rockers tend to oil the rocker boxes, not the valves)
  • 1.640 Ratio
  • Capable of .650″ max Valve Lift
  • Serviceable and rebuildable for generations of durabilty
  • A must have for cams with .550″ or greater lift
