    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.
