S&S Cycle Forged Roller Rocker Arm Set For Harley Milwaukee-Eight 2017-2026

S&S Forged Roller Rocker Arm Set For Harley M8

Big lift cams can unlock more high-rpm potential from the M8 powerplant, but they can also create added stress from stock valvetrain geometry. Excessive valve thrust and valvetrain wear led S&S Cycle engineers to develop stronger, more durable components that help riders get more from the M8. S&S Cycle Forged Roller Rocker Arms for M8 models are built to reduce strain on the rest of the valvetrain and are a key upgrade for improving component life on cams with more than .550" lift.

Features:

• Forged from 8620 steel for greater strength
• Designed using Finite Element Analysis
• Rollers eliminate thrusting on valves for decreased wear on the valve train
• Rocker geometry is better suited to high lift cams
• Bushings are 50% longer than stock, increasing time between rebuilds
• Larger surface area on the thrust surfaces reduces wear on the 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)
• Compatible with stock or S&S Cycle CNC heads
• 1.640 Ratio
• Capable of .650" max valve lift
• Serviceable and rebuildable for generations of durability
• A must have for cams with .550" or greater lift
