A cracked, warped, or leaking timing gear case can cause severe oil leaks, improper gear mesh, and inaccurate cam/crank synchronizing. The 4935569 housing is the exact OEM casting—no aftermarket variations—ensuring perfect alignment of the cam gear, crank gear, idler gear, injection pump gear, and accessory drive components.
This front cover is compatible with the 2003–2007 ISB 5.9L platform and the full 2007.5–2018 ISB 6.7L platform used in Ram 2500/3500/4500/5500 trucks, as well as various industrial QSB applications. Always inspect the crank seal, wear sleeve, and front cover gasket during installation.
