Free standard shipping on select products
We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.
Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
If your machine isn’t shifting like it should, our ShiftSpring is the solution. No gimmicks—just smooth, reliable engagement and a better driving experience without the high-dollar price tag.
Keeps Your Low Engagement Point
We match the stock spring rate, so you keep that low engagement feel you’re used to—no harsh engagement or unnecessary stiffness like other aftermarket options.
Simple. Effective. Affordable.
This is one of the easiest and most cost-effective upgrades you can make. No need to tear your clutch apart or send it off—just swap the spring and feel the difference.
No Shipping. No Downtime.
Keep your clutch where it belongs—on your machine. The ShiftSpring installs with a Primary Splitter Tool, so you can knock it out in your own garage or pit.
Pro Tip from the Race Shop:
A dirty clutch is a slow clutch. If you’re still having shifting issues, it’s probably time for a cleanout. Blow out your clutches regularly to prevent dirt buildup and keep things running like they should.
Please allow 3–7 business days for shipping. We only ship to the lower 48 states.
On some items, our live inventory may be depleted from previous days’ sales. In these cases, we may drop ship the item once it becomes available. If inventory is not in stock at the time of fulfillment, ATU will notify you with a resolution regarding backorder status.
Please be advised that ATU ships from over 10 warehouses across the U.S. In some cases, items may be drop shipped to help speed up delivery times. On heavily discounted parts (i.e. differentials), tracking information may not be provided.
Our site is always available whenever you want to upgrade your ride. Orders can be placed 24/7/365.
