Compatibility / Fitment:

Fits single overhead cam Cummins ISX15, X15 and QSX15 engines with a cylinder head on casting 4298234 or one of its interchangeable castings.

Two hard fitment gates apply:

Single overhead cam only. This head will not fit dual overhead cam (DOHC) ISX engines, which use a different head. Confirm your engine has one camshaft, or check by engine serial number (ESN) or CPL, before ordering.

Casting number. Check the casting number on your old head. This head replaces casting 4298234 and the interchangeable castings listed below. If your old head carries a different casting number, confirm the match before ordering.

What is not included: Valves, valve springs and injectors. Install your valvetrain before fitting the head, and reuse your existing injectors or supply a replacement set. Head gasket set and head bolts are sold separately.

Pair with: ISX / QSX single-cam cylinder head install kit, with head gasket set, head bolt kit, thermostat, and exhaust manifold bolts and spacers.

Other versions available: DCW new loaded with Inconel intake valves, all Inconel valves or a fire ring, DCW Premium, and DCW remanufactured loaded or bare, which we also stock.
