Diesel Proof Shipping Policy

Last Updated: September 22, 2026

At Diesel Proof, we work with leading manufacturers and distribution partners across the diesel performance industry to provide quality parts for your truck. Because products may ship directly from Diesel Proof, a manufacturer, or one of our distribution partners, shipping times, carriers, and shipment origins may vary by product.

Our goal is to make the shipping process as straightforward as possible while keeping you informed throughout your order.

Where We Ship

Diesel Proof currently ships to the 48 contiguous United States and Washington, D.C.

At this time, we do not ship to:

• Alaska
• Hawaii
• U.S. territories
• International destinations

Certain products may also have additional shipping restrictions based on size, weight, manufacturer requirements, or carrier limitations.

Shipping Rates

Available shipping methods and applicable charges are displayed during checkout.

Some products or qualifying orders may be eligible for free shipping, while others may require a shipping charge based on the product, order value, shipment type, destination, or manufacturer.

Heavy, oversized, truck-freight, and other specialty products may be subject to additional shipping charges regardless of order value or other free-shipping promotions.

The shipping rate displayed and accepted during checkout will generally be the shipping charge associated with your order. In the uncommon event that a carrier, manufacturer, or freight provider identifies a significant shipping discrepancy after an order is submitted, Diesel Proof will contact you before proceeding with any additional charge.

Free Shipping

Products or orders advertised as eligible for free shipping will receive free standard shipping when all applicable requirements are met.

Free shipping does not automatically apply to every product or order and may exclude oversized products, freight shipments, transmissions, fuel tanks, exhaust systems, and other products requiring special handling.

Where applicable, free shipping eligibility will be reflected during checkout.

Order Processing & Product Availability

Many Diesel Proof products ship directly from our manufacturers and distribution partners. Processing times therefore vary by product and fulfillment location.

An order confirmation indicates that we have received your order. It does not necessarily mean that the product has shipped or that manufacturer inventory has been independently verified.

We make every effort to maintain accurate product and availability information. However, manufacturer and distributor inventory can change without notice. If an item is unavailable, backordered, discontinued, or otherwise unable to ship within a reasonable timeframe, Diesel Proof will contact you with available options before proceeding.

Orders containing multiple products may have different processing times.

Multiple Shipments

Your order may arrive in more than one shipment.

Diesel Proof works with multiple manufacturers, warehouses, and distribution partners throughout the United States. If your order contains products fulfilled from different locations, those products may ship separately and may arrive on different dates.

Separate tracking information may be provided for each shipment.

Receiving only part of an order does not necessarily mean other items are missing.

Shipping & Transit Times

Carrier transit times begin after an order has been processed and released for shipment.

Any shipping or delivery timeframe provided by Diesel Proof, a manufacturer, or a carrier should be considered an estimate unless expressly stated otherwise. Carrier delays caused by weather, holidays, service disruptions, high shipping volume, or other circumstances outside our control may affect delivery.

Diesel Proof cannot guarantee carrier delivery dates once a shipment has been transferred to the carrier.

Tracking Information

When tracking information becomes available, it will generally be sent to the email address associated with your order.

Please allow time for tracking information to become active after a shipping label is created. A carrier may not show movement until the package has been physically received and scanned into its network.

Orders shipping from multiple locations may receive multiple tracking numbers.

Freight & Oversized Shipments

Certain products—including some transmissions, fuel tanks, exhaust components, and other large or heavy items—may require freight or specialty shipping.

Freight deliveries may require additional coordination with the carrier. Customers are responsible for providing accurate contact information so the freight carrier can arrange delivery when necessary.

Please inspect freight shipments before accepting delivery whenever possible.

If a shipment arrives with visible damage, note the damage on the carrier's delivery documentation before signing. If the damage is severe, contact Diesel Proof before accepting the shipment whenever reasonably possible.

Photographs of the shipment, packaging, product, shipping label, and any visible damage may be required to assist with a freight or carrier claim.

Damaged Shipments

If your order arrives damaged, contact Diesel Proof as soon as possible after delivery.

Do not discard the product, shipping carton, pallet, packaging materials, or shipping labels while the issue is being reviewed.

We may request photographs or other documentation to determine whether the damage occurred during transit and to coordinate with the carrier, manufacturer, or distribution partner.

Shipping damage should be reported separately from product defects or warranty-related concerns.

Lost or Missing Shipments

If tracking shows unusual delays, a package appears to be lost in transit, or tracking indicates delivery but you cannot locate the shipment, contact Diesel Proof so we can help determine the appropriate next steps.

Carrier investigations and claims may require additional time to complete. Diesel Proof will work with the applicable carrier or fulfillment partner when appropriate, but carrier investigation timelines are outside our direct control.

Shipping Addresses

Customers are responsible for providing a complete and accurate shipping address when placing an order.

Please review your shipping information carefully before completing checkout.

If you discover an error, contact Diesel Proof immediately. We will make reasonable efforts to update the address before shipment, but address changes cannot be guaranteed once an order has entered fulfillment or has been transferred to a carrier.

Additional costs resulting from an incorrect or incomplete address, carrier address correction, redirection, or reshipment may be the customer's responsibility.

Order Changes & Cancellations

If you need to change or cancel an order, contact Diesel Proof as soon as possible.

We will make reasonable efforts to accommodate the request; however, changes or cancellations are not guaranteed once an order has entered processing, been submitted to a manufacturer or distribution partner, or shipped.

Special-order, custom, built-to-order, or manufacturer-processed products may be subject to additional restrictions.

Refused or Undeliverable Shipments

Orders that are refused, returned to sender, or deemed undeliverable by the carrier may be subject to applicable return shipping charges, freight charges, carrier fees, or other costs incurred as a result.

Any refund eligibility associated with a refused or undeliverable shipment will be determined after the product has been returned and evaluated.

Questions About Your Shipment

If you have questions about an order or shipment, please contact Diesel Proof and include your order number so we can assist you as quickly as possible.
