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.

Not impressed

These were very cheaply constructed. Even though they were the cheaper of the rollers available I expected them to be decent. However they were not. Immediately after opening I sent them back.

Poor quality

After about 4000 miles, I've now broken 3 of these. Maybe I just got a bad batch, but I just ordered a different brand and won't use the Proform rockers again.
