Frequently Asked Questions How do I know if my ISX15 uses a Single Overhead Camshaft? You can confirm by checking your engine serial number (ESN) and engine build data. If unsure, contact us and we’ll verify your ESN for compatibility. What’s the difference between an in-frame and out-of-frame rebuild kit? An in-frame kit allows you to rebuild the engine while it’s still installed in the truck. An out-of-frame kit is for full engine teardown, usually when removing the block for machining or major repairs. Does this kit include the cylinder head? No, this kit includes the lower-end and gasket components only. For a complete rebuild, we recommend pairing it with our Cummins ISX15 Cylinder Head (5394198 / 4374091). Are these parts OEM or aftermarket? All components meet or exceed OEM specifications. They are manufactured to deliver the same reliability and fit as genuine Cummins parts, with competitive pricing. What warranty comes with this rebuild kit? Every kit is backed by a manufacturer’s warranty covering defects in materials and workmanship. Contact us for specific warranty details.
