<p>We're proud to present the most comprehensive valvetrain innovation for the Powerstroke platform to date.  These were developed in conjunction with Jesel to be the strongest, highest quality rocker arm system on the market.  The kit includes Jesel's award winning forged steel, shaft mounted, adjustable rocker arms, tool steel rocker stands, ARP hardware and billet tool steel valve bridges<br></p> <p>This is a bolt on system, meaning ZERO clearancing or modification is required to surrounding components.  The Jesel rocker system will work with factory style hydrualic lifters, but will require a different length pushrod.  <br></p> <p>Rockers will be available with our custom KDD chromoly pushrods, as well as as our Jesel Solid Roller Link Bar Lifters as well as our custom camshafts.  </p> <p> </p> <p><br></p>
