Frequently Asked Questions

Orders placed before 3 PM EST typically ship the same business day. Larger items may take 1 to 3 business days, and oversized and freight items take longer to prepare. Special order items follow their own lead time, which we confirm with you individually before the order is committed. Processing times are targets, not guarantees. See our Shipping Policy for full details.

Standard, expedited, and overnight options are available at checkout. The rate you see at checkout is the rate you pay for standard destinations. If a carrier applies a remote-area or special-handling surcharge to your address, or a freight shipment cannot be quoted precisely at checkout, that charge is the customer's responsibility. We will contact you with the exact amount before shipping, and you can cancel at no charge if you do not accept it.

Free shipping is an economy service with no guaranteed delivery date. It is the most affordable option, not the fastest. If you have installation time booked, choose a paid expedited service instead.

We ship from multiple warehouses, so a single order may arrive in several shipments on different days. You are never charged extra for split shipments, and each package gets its own tracking.

Yes. You will receive a tracking link by email as soon as your order ships. If an order ships in multiple packages, you will receive tracking for each one.

Orders of $550 or more may ship with signature confirmation required. This protects both you and us against porch theft on higher-value shipments.

Large items such as body panels, wheels, and exhaust systems ship by freight. The carrier will call to schedule a delivery appointment, so please provide a phone number you actually answer. Missed appointments and delayed scheduling can result in carrier storage fees.

Delivery is curbside. Inspect the shipment before you sign. If you see damage, note it on the delivery receipt before signing. Signing a clean receipt makes damage claims very difficult to win.

Some items can, but freight, oversized, and hazmat items cannot. Our Shipping Policy lists which destinations are supported for each shipping method.

Contact us immediately. If the order has not shipped, we can usually update it. Once a package is in transit, address corrections may not be possible, and any carrier intercept or reshipment fees are the customer's responsibility.

The item is not currently in stock. We will contact you with an estimated restock date and give you the choice to wait, choose an alternative part, or cancel for a full refund. Nothing ships until you decide. Once you have confirmed a backorder, cancelling after that point is subject to a 6% cancellation fee, since stock has been committed for you.

Check your spam and promotions folders first. Confirmations are sent immediately after checkout. If it is not there, the email address on the order may contain a typo. Contact us with your name and order total and we will locate the order and correct it.

Text (929) 352-6561 with the SKU, or submit a Backorder Inquiry through our contact page. Include the SKU from the product page so we can check the exact item.

Contact us as soon as possible. Before an order is packed or shipped we can usually cancel or modify it, and regular in-stock orders cancel free with a full refund. The 6% cancellation fee applies only to backorders and special orders that you have already confirmed with us. Once an order has shipped it must be handled as a return.

A special order is a catalog item that we do not normally stock and bring in specifically for you, at your request. We do not offer custom or made-to-order fabrication. Special orders are final sale and cannot be returned. They can be cancelled before you confirm the order with us at no charge; after you confirm, a 6% cancellation fee applies. Items are clearly identified as special order before purchase.

We accept all major credit cards, PayPal, and other secure checkout options. All transactions are encrypted, and we never see or store your full card details.

Yes. Sales tax is calculated automatically at checkout based on your shipping address and applicable state law. Tax is refunded in full on any returned merchandise.

Yes. If you are a shop, installer, or reseller, email support@onefastshop.com to apply for a dealer account. Include your business name and any applicable resale certificate.

Yes, on eligible items, against other authorized dealers. Request it before you order through our price match request form with a link to the competing listing and the SKU you want matched. We compare the total delivered price (item, shipping, and tax) and reply within one business day with a single-use code if it qualifies.

Eligible items are the identical part, meaning the same brand and same SKU, new and in stock at an authorized US dealer for that brand. We do not match marketplace or auction listings such as eBay and Amazon third-party sellers, unauthorized or gray-market sources, used, open-box, clearance, or pricing errors, or prices that depend on coupons, rewards, or member pricing. Some brands set a minimum advertised price, and we cannot match below that price on those brands. Price matches are not applied to orders already placed.

Some remanufactured parts include a refundable core charge. Once you return the old part in acceptable condition, the core charge is refunded. Core return requirements are listed on the product page.

Each product page lists fitment details. If you are unsure, contact us with the SKU and your vehicle's year, make, and model before you order. We would much rather confirm fitment up front than process a return.

Two ways to be covered. Select your vehicle with the vehicle selector on our site and the part shows as a fit, or send us your year, make, model, trim, and engine before you order and we confirm in writing. Either way, if the part does not fit that vehicle in factory configuration, the return is on us: no restocking fee, prepaid return label, and a full refund or replacement, even if you have already installed it.

Because an installation problem can look like a fitment problem, we will ask for photos of the clearance or interference issue and run through a short troubleshooting check with you before approving the return. The guarantee covers the vehicle as you selected or described it, so tell us about any modifications. If you ordered without selecting your vehicle or confirming with us and the part is wrong, it is handled as a standard return. Full terms are in Section 6 of our Returns & Refunds.

Yes. Every part we sell is brand new and factory packaged, never used, refurbished, or gray market. We are an authorized dealer for every brand we carry, so all products carry their full manufacturer warranty.

Not automatically. Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire factory warranty simply because you installed an aftermarket part. They must show the part actually caused the failure being claimed. That said, dealers vary in how they apply this, and a related failure can legitimately be denied. If warranty coverage is a concern, check with your dealer before installing.

It depends on the part. Some products carry a CARB Executive Order (EO) number and are street-legal in all 50 states; others are labeled for off-road, race, or competition use only and are not legal for use on public roads in California or other states that follow CARB standards.

Where a part has an EO number or a competition-use restriction, it is noted on the product page and by the manufacturer. Confirming that a part is legal for your vehicle and where you drive it is the buyer's responsibility. If you are unsure, contact us with the SKU before ordering. Unused, uninstalled competition-use parts can be returned under our standard 30-day terms, but a part not being street legal, failing an inspection, or not being permitted in your area is not an accepted return reason.

If you did not select your vehicle or confirm fitment with us before ordering, a wrong-part order is handled as a standard return: the item must be new and uninstalled in its original packaging, an 8% restocking fee applies, and shipping is not refunded in either direction. Request an RMA within 30 days of delivery.

If our vehicle selector showed the part as a fit, we confirmed fitment in writing, or the fitment information we published was wrong, it is our error and the return is free. See "What does Fitment guaranteed mean?" above.

Usually no. Installing a part signals acceptance, and installed or used parts cannot be returned or resold as new. This includes parts that were test-fitted, torqued, heat-cycled, or exposed to fuel or fluids. Always confirm fitment before installation.

The exception is a fitment error that is ours: our vehicle selector showed the part as a fit for your vehicle, we confirmed fitment in writing before you ordered, or our published fitment data was wrong. In that case we accept the return even after installation at no cost to you. Send photos of the fitment issue and we will walk through a short troubleshooting check to confirm it is a fitment problem rather than an installation problem.

Yes, two ways, and there is no restocking fee on either. Option 1: order the correct part now so it ships immediately, and we refund the original once it is received and inspected. Option 2: return the original for store credit, then apply the credit to the replacement. The returned item must still be new, uninstalled, and in original packaging. Return shipping is your responsibility and the original shipping charge is not refunded, unless the exchange is the result of our error.

Instructions are supplied by the manufacturer and are usually included in the box or available on the manufacturer's website. We are happy to answer questions about fitment, part numbers, and what is included, but we are not an installation service and cannot walk you through the job. For anything involving fuel, brakes, or suspension, we strongly recommend a qualified installer.

You have 30 days from delivery to request a return and ship it back; the window does not extend once an RMA is issued, so start early. Items must be new, uninstalled, and in original packaging with all hardware and documentation. Full terms are in our Returns & Refunds.

Yes. Every return requires authorization first. Do not ship anything back before you have an RMA. Write the RMA number on the shipping label and the outside of the box, put the RMA form inside, and insure the shipment. Returns without an RMA on the outside are refused. Submit a Return or Exchange request through our contact page with your order number.

Standard returns carry an 8% restocking fee on the item price before tax and shipping. Tax is refunded in full. The fee is waived on exchanges, defective items, and any error on our end, including a fitment we confirmed.

Shipping is not refunded in either direction on a standard return: the original shipping charge is not refunded and you pay return shipping. If the item arrived defective or damaged, we sent the wrong item, or the fitment error is ours, we cover it with a prepaid label and refund the original shipping too.

Installed or used parts, special orders, coilovers, electronics, engine internals, turbochargers, superchargers, turbo kits, hazardous materials, gift cards and store credit, and anything outside the 30-day window. Defective or wrong-item cases in those categories are still covered. The one exception for installed parts is a confirmed fitment error on our side. Category rules are listed in our Returns & Refunds.

Once your return arrives and passes inspection, the refund is issued to your original payment method. Depending on your bank or card issuer, it can take a few additional business days to appear on your statement.

If a discount or promotion was applied to your order, returning part of it may change what you originally qualified for. Percentage discounts are refunded proportionally, and if a return drops your order below a promotional threshold, such as a free shipping or spend-and-save minimum, the value of that promotion is deducted from your refund. Your refund breakdown will show this clearly.

Email support@onefastshop.com with clear photos of the item, the box inside and out, and the shipping label. Do not discard the packaging. Carriers require it to process a claim. Report transit damage promptly so we can file within the carrier's claim window.

Report defects within 7 days of delivery, including on third-party brands. We will cover return shipping with a prepaid label and send a replacement or issue a refund. Defects on third-party products reported after 7 days are handled through the manufacturer's warranty, and we will help you start that claim. Do not install a part you suspect is defective. Installation limits your options.

OneFastShop products carry a 1 year warranty against manufacturing defects. Third-party products carry the manufacturer's warranty. If a third-party product arrives defective, report it to us within 7 days of delivery and we handle it directly; after that, claims go through the manufacturer's warranty program and we will help you start the process.

Tuning alone does not void the OneFastShop warranty. Exclusions such as abuse, improper installation, and competition use are listed on our Warranty page.

Check with neighbors and your building first, then contact us within 15 days of the delivery scan so we can open a carrier investigation. Once a package shows a delivered scan, responsibility transfers to the customer, but we will do everything we can to help resolve it.

First check whether your order shipped in multiple packages. The rest may still be in transit. If a box arrived short, contact us with your order number and photos of the packing slip and box contents.

Yes, we ship worldwide. Rates and transit times are calculated at checkout based on destination. Some items cannot ship internationally due to size or hazardous material restrictions.

No. Prices at checkout do not include VAT, customs duties, or import fees. These are assessed by your country at the time of import and are the buyer's responsibility. Refused shipments that return to us are treated as standard returns, and duties are not refundable.

Hazardous materials such as aerosols, batteries, airbags, and some fluids ship ground only within the contiguous United States. They cannot ship internationally, by air, or to Alaska, Hawaii, or APO/FPO addresses, and they are final sale.

Yes, under the same 30-day terms, but return shipping, duties, and any customs charges on the return are the customer's responsibility. EU customers have additional withdrawal rights described in our Returns & Refunds.
