Proform 66906B Details
We completely overhauled the design of these rockers to make an overall better product.
A super affordable way to reduce internal valve train friction and valve stem wear. Extra long slot eliminates rocker to stud interference when using high lift cams. 16 rockers, anti-gall grooved balls and nuts per package.
