12V Harland Sharp Roller Rocker Assembly

Set of (6) Harland Sharp 12V Cummins 2024 Billet Aluminum Roller Rocker Assemblies with upgraded steel support bases. These upgraded bases eliminate rocker pedestal deflection and have been tested to over 6k RPM on PDD’s UCC truck.  For customer’s running a WarHead, these upgraded bases also work well to cover up the freeze plug oil leak that occurs when using factory pedestals on a Hamilton War Head.  Although these billet rocker arm assemblies are available custom order with increased rocker ratios, we recommend staying with the factory 1.7:1 ratio.  If you’d like a custom rocker ratio, please call-in to place your order.
