About Us

OneFastShop is an online retailer of aftermarket performance parts, founded in 2018 and operated as OneFastShop LLC, a registered United States business based in New York, with warehouse locations across the United States. What started as a garage passion project now supplies enthusiasts across the country with 39,000 parts from 73 brands, covering European, Japanese, and American performance platforms.

If you landed on this page because you are about to spend real money on a set of coilovers, a turbo kit, or a full exhaust and you want to know who you are buying from, this page is written for you. Here is exactly how we operate.

Where Our Parts Come From

Every part we sell is brand new, factory sealed, and genuine, exactly as the manufacturer built it. When you order a Bilstein damper or an Akrapovic exhaust from us, you receive the manufacturer's part in the manufacturer's packaging, with the manufacturer's warranty intact.

We are an authorized dealer for every brand we carry, never a gray market seller. That includes APR, Dinan, do88, Akrapovic, KW, Bilstein, Ohlins, AWE, Eibach, H&R, Brembo, HKS, Skunk2, AMS, Mishimoto, CSF, Turbosmart, Radium, Walbro, DeatschWerks, Garrett, Borla, Magnaflow, Corsa, and Kooks. Because we are authorized, the manufacturer warranty applies to every part we sell, and our price match covers other authorized dealers.

How Your Order Reaches You

Orders ship from our warehouse locations across the United States, routed to whichever one has your part on the shelf. That keeps the trip short and gets the box to you faster than pulling every order through one central hub.

What matters more is who is accountable. OneFastShop is the seller of record on every order. We place it, we track it, we chase the carrier when a shipment stalls, and we handle it if the part shows up wrong. You deal with us from checkout until the box is at your door. You will never be told to take it up with someone else.

Fitment Comes First on High Value Parts

The most expensive mistake in this hobby is ordering a part that does not fit your car. Our listings carry manufacturer fitment data, and our catalog is organized by platform so you can narrow down to parts built for your chassis rather than guessing from a photo.

If anything is unclear, contact us before you order with your year, make, model, trim, and engine code. We will check the part against the manufacturer's application data and tell you plainly whether it fits, including when the answer is no. We would rather lose a sale than send you a $2,000 part that ends up back in a box. And our fitment guarantee is simple: if our vehicle selector shows a part as a fit for your vehicle, or we confirm fitment in writing before you buy, and it turns out to be wrong, we make it right at no cost to you, even if the part has already been installed. We will ask for photos and a quick troubleshooting check so we can confirm it is a fitment issue rather than an installation issue. If you did not verify with us and the part turns out to be wrong, it is handled as a standard return.

What Happens After You Order

Orders placed before 3 PM EST typically ship the same business day. Larger items may take 1 to 3 business days, and special order items follow a lead time we confirm with you individually. As soon as your order ships you receive a confirmation email with tracking so you can follow the package the whole way.

Standard economy ground shipping within the contiguous United States is free on eligible items. Oversized products, including freight items such as bumpers, are quoted at checkout. Full details are in our shipping policy.

If Something Goes Wrong

You have 30 days from delivery to request and ship back a return on an unused item in its original packaging. Standard returns are subject to an 8 percent restocking fee on the item price, and shipping is not refunded in either direction.

If the part arrives defective, damaged, or incorrect, or the error is ours, the restocking fee is waived and we provide a prepaid return label. In those cases we evaluate the issue and provide a replacement, exchange, or full refund at no additional cost to you. Approved refunds are credited to your original payment method within 10 business days. The complete terms are in our Returns & Refunds policy.

Built by Enthusiasts, for Enthusiasts

We are not a generic retailer that added a performance category. We are enthusiasts who understand the difference between a part that makes numbers on a dyno sheet and a part that actually improves how a car drives. That is why the catalog leans toward downpipes, intercoolers, fueling upgrades, exhaust systems, turbo kits, intake systems, suspension, and braking rather than filler.

Since 2018, thousands of enthusiasts have trusted OneFastShop with their builds, from weekend track cars to daily drivers chasing a full bolt-on setup. Their feedback is why we keep expanding the catalog and tightening the way we do business.

Talk to a Person Before You Spend

Questions about fitment, lead times, freight, or which of three options actually makes sense for your build are welcome before you buy, not just after.
