    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.

    66868 is rated 3.0 out of 5 by 2.
    Rated 5 out of 5 by from great valu I have been running these on my 440 for years on the street at a .450 to .480 lift. When I bought them they came with shims and springs for proper location on the valves. I also had to buy different push rods to go with them.

    Will these clear the valve springs/retainers on the TrickFlow PowerPort 240 aluminum heads?

    Asked by: JoeSolo814
    These rocker arms should clear the retainers on the trick flow heads, but keep in mind the 450lb open pressure that these rocker arms can handle.
