Tesla Model S / Model S Plaid (2021 – 2026+) Billet Adjustable Rear Toe Arm Set

Rear toe controls how the rear wheels point relative to straight ahead, and it has a big effect on stability and tire wear. A touch of toe-in adds high-speed stability; too much of the wrong setting scrubs tires and makes the car feel nervous or lazy. The factory arm is not built for precise tuning, so this adjustable billet toe arm lets you set the rear exactly where you want it.

It replaces the stock toe link, Tesla part number 1420435-00-D, with a stronger, lighter billet aluminum arm running high-performance sealed spherical bushings instead of rubber. The spherical bushings hold your toe setting precisely and operate silently, where worn rubber lets toe drift and adds vagueness. Tesla’s 2021+ 5-link rear is a capable design, and this is our re-engineered link built for performance driving and repeatable alignment.

Yes. The set fits 2021 through 2026+ Model S and Model S Plaid, and the page specifically confirms fitment on the 2026+ Model S Plaid refresh. Both the Plaid and Long Range share the rear suspension, so either trim works. It is not compatible with pre-2021 cars, which use an earlier rear end. Match your car to the 2021+ range and it bolts into the toe position.

It is CNC-milled from 6061 aluminum for strength while saving weight, and FEA-simulation optimized for static, dynamic, and fatigue strength. Like the rest of our rear arms, development began with a precise 3D scan of the suspension to build a digital model, then real racing and street testing on our own cars. The program traces back to our Dark Helmet Plaid race car and its Pikes Peak class win.

It leans toward handling and precision rather than fixing a worn-out car. You fit it to gain accurate, repeatable rear toe control and to tighten how the rear feels, not primarily to cure knocking like the front lower compliance arms do. The sealed spherical bushings do outlast soft factory rubber, so there is a durability benefit too, but the main reason owners buy it is control over the alignment.

Toe and camber arms solve different problems, and they pair naturally. Toe arms set the rear wheels’ direction; the adjustable rear camber arms set their lean. If you have lowered the car, you usually want both to fully correct the rear alignment and stop uneven tire wear. Many owners buy them together, and the full suspension package bundles them with the other rear links plus a sway bar and lowering.

Yes. Any alignment shop comfortable with Tesla vehicles can install the toe arms and set the rear toe on a rack, and our Hawthorne team can do it for owners near Los Angeles. Because you have added real adjustment capability, an alignment afterward is the point, not an afterthought. Once set, the spherical bushings and adjuster hold the number instead of letting it wander.

It is a big part of the fix. Lowering changes rear toe and camber together, and incorrect toe is a common cause of feathered, uneven rear tire wear. Correcting toe with these arms, ideally alongside adjustable camber arms, lets you return the rear to a wear-friendly alignment. The result is tires that last closer to their rated mileage and a rear end that tracks straight and steady.

Stock toe links give you whatever adjustment Tesla built in, which is limited, and their rubber bushings let toe move under load. These billet arms add a precise, lockable adjustment and remove the deflection, so you can both set a better number and keep it. If you never plan to touch alignment and your bushings are healthy, stock is fine. If you want to tune the rear, these are the tool.

Fitting them does not automatically void your Tesla warranty. Under Magnuson-Moss, Tesla must show the arm caused a specific failure before denying a related claim, so the swap itself is not disqualifying. Hold onto the factory toe links you remove in case you want to go back to stock. These arms are also covered by our own suspension warranty for added confidence.

Tesla’s warranty covers factory-installed parts, but it does not automatically void your warranty if you install aftermarket components like Unplugged Performance brake kits. Under U.S. law (Magnuson-Moss Warranty Act), Tesla must prove that an aftermarket part caused a failure in order to deny warranty coverage. Our parts are engineered to work harmoniously with Tesla OEM Brake systems and can be professionally installed by Unplugged Performance in Hawthorne, CA or by an authorized installer to minimize risk. That said, any damage directly caused by misuse or improper installation may not be covered. We recommend retaining all factory parts so you can revert to stock if needed. Many Tesla owners enjoy peace of mind by using Unplugged Performance products, which are extensively tested and installed by certified professionals. If warranty concerns are top-of-mind, our team can help clarify compatibility and installation best practices to ensure a worry-free experience.

Unplugged Performance offers a comprehensive warranty on all parts and installations performed by our certified technicians. Warranty coverage applies to defects in materials and workmanship on items including lowering springs, coilovers, big brake kits, brake pads, stainless steel brake lines, shocks, and more. Should any covered part fail under normal use or display premature wear, we will repair or replace it at no additional cost—assuming the component was installed by us or at one of our authorized partners.

This warranty is valid for 2 years or 24,000 miles, whichever comes first, excluding consumable products like brake pads, rotors, and tires, starting from the installation date. Coverage extends to labor for warranty repairs when performed by Unplugged Performance or an authorized installer. It does not cover damage resulting from misuse, accidents, off‑road use, improper installation not done by us, or modifications that aren’t factory-approved.

To file a warranty claim, simply contact our service team. We’ll guide you through inspection, shipping (if needed), and repair or replacement logistics. transparencia and top-tier support are what you can expect from Unplugged.

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.
