    Designed with the serious performance enthusiast in mind...

    Magnum Roller Rocker Arms are the ultimate street rocker arms, helping your engine make more power and last longer.

    Strength
    Made from 8620 chromemoly steel, Magnum Roller Rocker Arms are stronger than die cast aluminum or stamped steel rockers. Their stiffness guarantees maximum lift because the arms will not flex.

    Accuracy
    When your car's rocker ratio is off, you won't get maximum horsepower from the engine. Some rockers are as much as .040'' short on lift while Magnum Roller Rockers are dead-on each time.

    Power
    Magnum Roller Rockers make between 15 and 30 horsepower over other rockers because, combined with their stiff design, the roller tips reduce friction, yielding more effective valve lift.

    Durability
    The roller tip design reduces friction by not scrubbing the valve end or pushing the valve stem hard against the valve guide, which extends rocker life.

    1412-16 is rated 4.3 out of 5 by 3.
    Rated 5 out of 5 by from Roller rockers You need to buy the poly locks, cause a reg socket can't get inside the rocker very well to adjust it. And the poly locks are the bomb.!!!!

    Rated 5 out of 5 by from Quality, easy to install Good quality part, affordable price and easy to install.

    Rated 3 out of 5 by from Ok Very difficult to adjust. Cant find a socket thin enough to fit between the wall of the rocker and the nut
