Upgrade your stamped steel rocker arm bridges to precision machined billet pieces from Fleece Performance Engineering. Built for the 1998.5 and newer 24V Cummins, these billet rocker arm bridges deliver the ultimate in valvetrain stability and strength — a direct upgrade over the factory stamped steel components that are a known weak point on high-performance and high-mileage 24V builds.

The factory stamped steel rocker arm bridges flex under load, especially in high-performance applications with aggressive camshaft profiles, upgraded valve springs, or high lift. Fleece's billet machined replacements eliminate that flex, providing a more consistent and stable valvetrain that holds tolerances tighter under sustained high-output use.

Direct replacement fitment for all 1998.5 and newer 24V Cummins applications. A worthwhile upgrade any time the valve cover is off — especially when installing upgraded valve springs, performing a head rebuild, or building for high performance.
