How We Can Help
- Fitment help: send us your engine model and serial number, and we will confirm the right cylinder head, inframe kit or injector set.
- Quotes and invoices: ask for a quote, or request an invoice so you can pay with Affirm.
- Cores and warranty: questions about core returns or a claim? Read our warranty policy or call us.
What to Have Ready When You Call
A few details help us find the right part faster and avoid returns:
- Engine make and model, such as Cummins ISX15 or Caterpillar C15
- Engine serial number from the data plate
- The part number on the old part, if you have it
- Your shipping ZIP code, so we can quote freight on heavy items
