Backed by the Best

Quality comes first at Detroit Diesel. When you're #1, it has to. That's why we back each DD15 with a standard, comprehensive warranty as rugged as the engine itself. It's part of our dedication to providing the best product support available in the industry.

Plus, you can even toughen up your warranty with special extended coverage options available through your Dealer or Distributor. And because Detroit Diesel engines hold their resale value, your warranty is transferable to future owners—no extra charge.
