Tesla Model X / Model X Plaid (2021+) Billet Adjustable Rear Camber Arm Set

Lowering a multi-link car pulls the rear wheels into extra negative camber, so the inner edges of the tires scrub faster than the rest. The factory rear arms give you no way to pull that camber back toward neutral. This billet camber arm set does, letting you correct the angle and even out the wear. On the street, that is the main reason owners fit it.

The set offers the largest possible range on this platform, from +1 to -4.5 degrees of camber. That span covers everything from a neutral street alignment that protects tire life to an aggressive negative setting for maximum grip on track. Few adjustable arms open up that much room. It means one set of arms serves both the daily driver and the track-day crowd.

They fit the 2021+ Model X and Model X Plaid, which share the new multi-link rear suspension. The set is priced at $1,610.75, down from $1,895.00, under SKU UP-MSMX2-103-4.1, and ships the next business day. Owners dialing in a full rear alignment usually add the matching rear toe arms alongside them.

CNC-milled billet 6061 aluminum for the arm bodies, sealed spherical bushings at the pivots, and high-strength stainless steel adjustment mechanisms. That combination gives you strength alongside precise, silent movement from an adjuster that holds its setting. The design is FEA-optimized for static and long-term fatigue strength. It is built to survive the same abuse we put it through on the race car.

Our ‘Dark Helmet’ Model X Plaid race car, which took a Pikes Peak class victory and set multiple production-based EV lap records. Chasing setups for Pikes Peak and record laps at Laguna Seca and Buttonwillow meant doing alignment after alignment, which is exactly what shaped these arms for both maximum adjustment and real usability at the rack. That development transfers straight to your car.

Very, and that was a deliberate engineering goal. The multi-link rear end is a genuine challenge to adjust, so these arms were designed so the technician doing the alignment can actually reach and set them without a fight. Maximum camber range means nothing if a shop cannot dial it in. Our Hawthorne team can install and align, or any capable alignment shop can.

Not automatically. Under the Magnuson-Moss Warranty Act, Tesla must show that these arms caused a particular failure before denying a claim; their mere presence is not grounds. Our race results and warranty back the hardware. As always, hold onto the factory arms you take off so you can return the car to stock spec whenever you choose.

If you have lowered the Model X, yes, mostly to save your tires. Street drivers fit these to neutralize the uneven wear that lowering causes and to correct the camber that builds at highway speeds. Track drivers fit them to maximize the tire’s contact patch under load. Same arms, two different jobs. If your car sits at stock height and you never lower it, the need is smaller.

The factory arms are set-and-forget with no adjustment, which is fine until you lower the car or want to fine-tune grip. These replace them with a fully adjustable, stronger billet arm that puts camber in your control from +1 to -4.5 degrees. They pair naturally with the billet rear lower fore link for a fully upgraded rear axle. For a modified or tracked Model X, that control is close to essential.

It does. Setting negative camber keeps more of the tire flat on the road when the car leans in a corner, which enlarges the contact patch right when you need it. That translates to more mechanical grip through the turn. On a heavy Model X pushed hard, dialing camber to suit the tire is one of the higher-value rear suspension changes you can make.

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.
