    One of the best ways to rid an engine of internal friction is with a set of roller rocker arms. Except for Chrysler shaft mount rockers, Proform's race-proven full needle bearing fulcrums and roller tips unleash horsepower, eliminate valve stem tip wear and tear, and extend valvetrain component life. These aluminum roller rockers are precisely machined to ensure ratio accuracy and consistency.

    JEGS Easy Kits are designed by JEGS professionals to ensure that you get all the correct parts you need.

    66861C is rated 1.0 out of 5 by 1.
    Rated 1 out of 5 by from Junk!!!! Purchased these roller rockers because the ones I wanted weren't available. When they came in I wasn't impressed at all! First the packaging isn't like how other manufacturers' roller rockers come, very cheap! Then I opened the package to inspect one and the roller tip felt as if there were no bearings in it whatsoever, very sloppy tolerances! That being said I contacted Jegs immediately and got the ball rolling on the return process!
