Dodge Magnum Adjustable Roller Rockers

Moving further ahead in our Modern Line of Custom Series roller rockers, In 2000 we assisted in the development and R&D of the First True Dodge Magnum Custom Billet Adjustable roller rocker. Borrowing the design of our first successful shaft style rockers, we added a larger wider rocker body, larger pins and rollers including lash adjusters for more demanding engine use and valve spring pressures. Designed for Custom Engine builders to create a BluePrinted valvetrain with Custom Length pushrods. These new adjustable rockers can be found as standard equipment on all our Precision Built Performance Engines.
