Product warranties may vary depending on the manufacturer, product type, supplier, application, and the terms that apply to the specific product.

High Torque Diesel LLC may assist customers with available warranty information, but manufacturer warranties are generally controlled by the manufacturer and are subject to the manufacturer’s own terms, limitations, exclusions, and claim procedures.

Shipping for Warranty Claims

Replacement-product shipping may also depend on the manufacturer’s warranty terms.

Warranty Replacement Products

If a manufacturer approves a replacement, the replacement product may be subject to the original warranty period, a replacement warranty period, or other manufacturer-specific terms.

High Torque Diesel LLC does not determine those terms unless specifically stated.

Returns vs. Warranty Claims

A warranty claim is different from a standard return.

Products that are:

• Installed
• Used
• Programmed
• Modified
• Outside the standard return window

may not qualify for a normal return but may still be eligible for manufacturer warranty review.

Please review our Returns & Refunds Policy for standard return requirements.

No Additional Warranty Unless Stated

Unless specifically stated in writing, High Torque Diesel LLC does not provide an additional product warranty beyond any applicable manufacturer warranty.

Any manufacturer warranty remains subject to the manufacturer’s own terms and conditions.
