About Us

We are now an online store only. Sorry no phone business at all.

With 26 years of diesel experience, DieselTuff's been at it longer than the most other sellers and we will bring you only the very best in parts and tech help for the products we sell. 

 From a vast knowledge base and working with only the best venders in the business, DieselTuff's has tested and or used most of the parts we sell for your diesel truck or car.

From mild to wild, let DieselTuff's help you choose the right part for your application. Whether it's fuel mileage or all out diesel performance of 1000+hp, we have built it.

The best prices and free ground shipping to the lower 48 states and Canadian border Provinces, on product over $100 (inj pump sales, any services and some other parts are exempt)...How do we do this? Simple, because we simplified the buying process. Instead of playing phone tag or waiting on hold, we offer web based sales, tech help and parts help via e-mail only.
We will reply back in minutes in most cases. This allows us the time to offer our parts at the lowest price, period.

Availible 7 days a week, from 7am til 10 pm PST.
Serving USA & Canada

Thanks for considering DieselTuff.
