Returns Policy

  1. General Return Policy:
    Due to the specialized nature of our products, we generally do not accept returns. Most items are VIN-specific or custom-built to order.

    All sales are final. If you cancel your order after it has been placed but before it has shipped, a 5% processing fee will apply.
  5. Non-Returnable Items:
    Certain items, such as hard parts (e.g., EGR kits, DPF pipes/exhaust, pyro kits, throttle valve kits, exhaust tips, and intakes), are not eligible for return unless an exception is made. If an exception is granted, a 30% restocking fee will be applied, along with the cost of return shipping.

Customer Testimonials

Sasquatch Diesels transformed my truck's performance!

I recently purchased a new brake pad for my truck, and I couldn't be happier with the performance. The installation was straightforward, and the stopping power is significantly improved. Highly recommend! So what are you all up to this fine day? I really have some big questions that need to be answered.
