Roller Rocker Arms only or Rocker Arm Guardian Kit - 1.640 Rocker Ratio for M8

 M8 S&S Roller Rocker 

• Designed using Finite Element Analysis (FEA) and forged from 8620 steel for strength
• Eliminate thrusting on valves for decreased wear on the valve train
• Rocker geometry is better suited to high-lift camshafts
• Bushings are 50% longer than stock, increasing the time between rebuilds
• Oil is sprayed directly on the valve springs, reducing the potential for valves breaking due to overheating
• Compatible with stock or S&S CNC-machined heads
• Works well for cams with 0.540"
• Capable of 0.650" max valve lift
