Unused returns and warranty replacements follow different policies. Choose the route that matches your belt.
30-day return window
You may request a return within 30 days of delivery.
Eligible returns
Serpentine belts must be new, unused, uninstalled, clean, unmarked, and returned with the original packaging. Proof of purchase is required.
Installed, run, contaminated, altered, damaged, or incomplete products are not eligible for a routine return. Covered wear and defects follow the separate limited lifetime warranty; the routine-return restrictions and 30-day return window do not restrict a valid warranty claim.
Start a return
- Email Michael@easysupply.us within the 30-day window and include your order number and reason for return.
- Wait for return authorization and shipping instructions.
- Package the product securely. Returns sent without authorization may be delayed or refused.
Return shipping
The customer is responsible for return shipping on ordinary returns and customer fitment-selection errors. Easy Diesel will cover reasonable return shipping when we sent the wrong product, the product arrived damaged, or our published fitment information or direct fitment recommendation was incorrect.
Refunds
After the returned product is received and inspected, eligible refunds are issued to the original payment method within 2–4 business days. Your bank or card provider may require additional time to post the credit.
Original shipping charges are not refundable unless the return resulted from our error or the product arrived damaged or defective.
Fitment questions
Before installing a belt, compare the product, routing, rib count, and application information with the belt being replaced. If anything appears different, do not install it. Contact Michael@easysupply.us or use our fitment request form.
Lifetime belt guarantee
Limited U.S. warranty: defects and normal wear are covered for as long as the original purchaser owns the same truck. Parts only. Qualifying purchases on or after September 13, 2026.
