S&S Cycle Forged Roller Rocker Arms For 17-20 M-Eight

• 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
• 1.640 ratio
• Capable of .650" max valve lift
• Serviceable and rebuildable
• Must-have when using cams with .550" or greater lift
• Made in the U.S.A.
