Race-proven power.

These Proform extruded aluminum roller rocker arms will help rid your engine of internal friction. They feature a race-proven, full needle-bearing fulcrum and roller tip. And they not only unleash horsepower, but they also lengthen valvetrain component life and reduce wear and tear on valve stem tips. These rockers are precision-machined to ensure consistency and ratio accuracy, and they have a great looking blue anodized finish.
