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
