Tesla Model S Front Upper Control Arm Ball Joint Replacement (2021 – 2026+)

Because the FUCA uses a flip pill, keeping a spare replacement joint lets you switch between a street alignment and a track alignment in minutes rather than booking an alignment each time. Racers who move between road camber and slick camber often keep an extra on hand for exactly this. For most street owners it stays a wear-replacement part, not something you touch often.

Watch for new play, clunking, or looseness in the front end, or a ball joint that no longer holds its setting cleanly. Hard use accelerates it: repeated high-speed, high-grip cornering on street or track wears the joint faster than gentle commuting. Since it is sold per side, you can replace one or both depending on what your inspection shows. When in doubt, our team can help you diagnose it.

The $180.00 is per side. If you are refreshing both front corners, you order two. Selling it individually keeps the cost down when only one joint has worn, which is common when one side has taken more abuse from a particular road or track direction. The part ships the next business day, so a track weekend rarely has to wait on it.

If you are comfortable working on the FUCA, the joint swap is a manageable job at home with basic tools, and the flip-pill design is meant for quick changes. Set your camber afterward, since disturbing the joint changes alignment. Owners in the Los Angeles area can have our Hawthorne shop handle it and confirm the setting on the rack. Keep the retainer hardware clean and torqued to spec.

No. If you do not own the Unplugged Performance FUCA, Ultimate Edition, this replacement joint has nothing to bolt into. Start with the front upper control arm set, which brings adjustable camber, caster, and toe and comes with the pill already installed. Buy this part later, once your joints have logged real miles and need refreshing.

There is no fixed mileage; it depends entirely on use. A daily-driven Model S can go a long time, while a car that sees frequent track sessions with sticky tires wears the joint sooner because cornering loads are far higher. Treat it like brake pads or tires: a consumable you renew based on inspection, not the calendar. Keeping a spare on the shelf means downtime is short when the day comes.

No, it is specific to the Model S FUCA. The Model 3 and Model Y use their own front upper control arm and ball joint replacement, so the parts are not interchangeable across those platforms. Always match the replacement to the exact arm set on your car. If you are unsure which you have, the SKU on this part is UP-MS2-102-2.1.

Renewing a wear item on an aftermarket control arm does not automatically void your Tesla warranty. Under Magnuson-Moss, Tesla would need to prove a specific failure was caused by the part to deny a related claim. This joint simply maintains a suspension arm you already run. Hold onto your factory arms so a return to stock stays possible if you ever want it.

This is the replacement pill and ball joint for the Unplugged Performance Front Upper Control Arm (FUCA) Set, Ultimate Edition. It is not a standalone control arm and only works with that FUCA set. Ball joints are a wear item in any car, and time, rough roads, or repeated high-grip cornering eventually wear them. This part keeps your existing FUCA performing without buying the whole arm again. It is priced at $180.00 per side.

No. This replacement is for the 2021 through 2026+ Model S Front Upper Control Arm set, and it only fits the Unplugged Performance FUCA, Ultimate Edition. It will not service a factory arm or an older-generation Model S. If you have a 2012-2020 car, the front lower compliance and lateral aft arms are the relevant upgrade for that chassis instead.

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.
