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
