Tesla Model Y (2026+) High Efficiency Rear Fins

The listing notes orders ship mid 2026, and ordering now locks in the next available stock. As with any pre-order window, timing can shift, so if you are planning a full aero install around a specific date, contact our team first and we will confirm the current lead time for the fins.

They will not automatically. Under the Magnuson-Moss Warranty Act, Tesla cannot void your warranty just because an aftermarket part is on the car; it must prove the part caused a specific failure. A pair of tape-mounted fins that touch nothing mechanical give almost nothing to point at, and they peel off cleanly, so returning to stock before any service visit is quick.

As air travels down the body it can peel away too early and spill into the wake, which creates drag and a less settled feel. Mounted at the outer edges of the rear bumper, these fins act as subtle fences that help the airflow stay attached a little longer before it enters the wake. Keeping the side flow organized supports pressure recovery at the rear, so you get calmer air, better highway stability, and a more planted rear end.

Yes. They fit 2026+ Tesla Model Y Standard RWD, Premium AWD or RWD, and Performance trims. They are for the Juniper generation only and are not compatible with earlier model years. Because they mount at the rear bumper edges rather than relying on Performance-only bodywork, they suit a broad range of Juniper Model Y owners, which is unusual for aero on this platform.

They do both. The fins were developed within the same CFD process that shaped the full aero package, where the complete system reduced drag by about 40 newtons, roughly 2.4 percent, and improved net downforce by about 534 newtons in a 30 million cell transient model. On their own the fins contribute a tidier wake and a touch more confidence at speed by keeping side flow attached longer to help the diffuser and spoiler.

They use a simple double-sided 3M tape installation, so there is no cutting or drilling. You position each piece, press it into place, and you are done in minutes. If you ever want to return to stock, removal is just as simple. That tape-mount approach respects the vehicle and makes the fins equally suited to long-term ownership and leased cars.

You can. They work as a standalone upgrade and still tidy the rear wake and add a little stability on their own. They also pair naturally with the Rear Diffuser Extension and Efficiency Trunk Spoiler for a complete rear treatment, and up front the Front Splitter and Front Canard Set condition incoming air. Start with the fins, then add the full aero kit pieces if you want the whole system.

They come in a gloss black finish chosen to mesh with the Model Y’s trim for a true OEM-plus look. The design also continues the car’s original character lines so the fins read as a natural extension of the factory shape rather than a bolt-on. The intent is to sharpen the rear profile without shouting for attention.

It is one of the easiest. The fins are a small, low-cost aerodynamic upgrade that install with tape in minutes and need no tools or coding, so they are a friendly entry point before larger aero. Our Hawthorne team can fit them if you prefer, though most owners handle this one themselves. Clean the surface well before applying so the tape bonds properly.

No. Their whole job is to reduce turbulence by keeping side flow attached longer, which lowers drag rather than adding it, and they translate to smoother highway stability and better composure through long sweepers. They are subtle enough that you will not hear them; you mostly feel a slightly more planted rear end when cruising or changing lanes at speed.

Installing aftermarket parts does not automatically void your Tesla warranty. Under the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts), a manufacturer cannot void your warranty simply because you installed aftermarket parts. Tesla must prove that the aftermarket part caused the specific failure in question to deny a warranty claim. UP recommends retaining all factory parts to allow reverting to stock if needed.
