-
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 CNC heads

1.640 Ratio
