About this store

American Diesels LLC operates americandieselshop.com. These terms describe the conditions for using our store and purchasing our products. For questions, contact support@americandieselshop.com.

Products and fitment

Review the selected size, product specifications and fitment information before ordering. Exhaust elbow sizes identify the inlet and outlet diameters; they are not a guarantee of fitment for every truck. Confirm your existing exhaust diameter and available clearance. Trimming may be needed for your installation. Contact us if you need help choosing a configuration.

Prices, availability and orders

Prices are displayed in U.S. dollars. Applicable discounts, shipping charges and taxes are shown at checkout before you place an order. Provide accurate contact, billing and shipping information.

Products marked Coming Soon are not available to purchase. A release-notification request is not an order, reservation or preorder and does not guarantee a release date or availability.

Shipping

Orders ship within 3 business days; delivery time is additional. Shipping is calculated at checkout and shown before you pay. We ship to the lower 48 states and Washington, DC. See our Shipping Policy for the complete shipping terms.

Returns and order issues

Eligible unused items may be returned or exchanged for another size within 30 days of delivery. Polishes and sprays must be unopened. The buyer pays return shipping unless the error is on our end. Contact us before sending a return.

Report a damaged or wrong item within 7 days of delivery, and a defect within 30 days of delivery. We don't offer a warranty on our products. See our Return and Refund Policy for the details.

Notifications and applications

Signing up for early access or a product notification adds you to our marketing emails. You can unsubscribe at any time. Dealer and sponsorship inquiries are reviewed individually; submitting a form does not create an approved partnership or commit either party to an order.

Privacy and contact

Our Privacy Policy explains how information is collected and used. Send store, order and policy questions to support@americandieselshop.com.
