National Truck Protection® (NTP®) has been serving the medium-and heavy-duty used commercial truck industry with quality and reliable aftermarket warranty programs longer than any brand in North America. Since 1983, more owner-operators have trusted NTP to take care of their vehicles so that when major equipment like engine, after treatment, transmission, injectors, and fuel pump fail, NTP will be there. NTP has earned this level of trust because we stand behind our programs, taking care of repairs for coverage that you paid for, not hiding behind your warranty looking for ways to not pay for a repair. We pay tens of millions of dollars in repairs every year so you can quickly and safely get back on the road where you earn your living.

The Benefit of Having a Warranty

Used trucks will have equipment failure, it’s inevitable. Some will cost a couple of hundred dollars while other repairs can be catastrophic, costing tens of thousands of dollars. But no matter what the damage, if you have equipment or a part that fails and it is covered by the NTP warranty you bought, we’ll pay for that repair. It’s that simple.


  • WHEN you’ll need us. So, our experienced customer service team is available by email, phone, or through your personal self-service portal to take care of you. You don’t know.
  • WHERE you’ll be when your truck breaks down. So, we’ll help find you a repair center in our network of over 5,300 shops that’s convenient for you.
  • WHAT your problem is. So, our trained tech specialists will work with the mechanics to diagnose the problem and give you an honest recommended repair. Then, we’ll get your covered repairs started so you can get back on the road.

It might sound cliche but, it’s our business to keep you in business.
