Tesla Model S / Model S Plaid (2021 – 2026+) Adjustable Front & Rear Sway Bar

A sway bar ties the left and right wheels together so the car leans less in corners, which keeps the tires flatter and the chassis more balanced. On the Model S it is the upgrade you feel most for the money: less body roll and much sharper turn-in, in a more planted, stable car. Because these bars are adjustable, you can tune that effect toward comfort or toward aggression depending on the drive.

The front bar offers 2-way adjustment and the rear offers 3-way, so you can fine-tune balance for anything from a road trip to competition. Moving to a stiffer setting sharpens response for aggressive driving; a softer setting keeps the ride relaxed. That range lets you bias the car’s handling front to rear without changing any other component, which is why the adjustability matters as much as the bars themselves.

For most Model S Long Range and Plaid owners, the rear bar alone is the recommendation. It livens up the rear and sharpens turn-in, and it installs easily without major work. The front bar is aimed at owners who track or race the car, because fitting it means dropping the subframe and disconnecting the axles. You choose the front bar only, the rear only, or the full set at checkout, and the full suspension package includes these bars alongside lowering and the billet arms.

Yes. These bars are designed specifically for the 2021 through 2026+ Tesla Model S Plaid and Long Range, and the same product covers both trims. They were developed on our record-setting Dark Helmet race car for this exact chassis. They are not made for the pre-2021 Model S. Pick your configuration and confirm your car falls in the 2021+ range before ordering.

The front bar’s location requires dropping the subframe and disconnecting the axles to fit it, which is a deep, labor-intensive job. Because of that, there is a heightened risk that Tesla could deny a related warranty claim, and professional installation is strongly advised. We ask that you consult an Unplugged Performance specialist before ordering the front bar. The rear bar, by contrast, is a simple bolt-on that does not require that work.

Each bar comes with high-performance polyurethane bushings, bushing brackets, a grease packet, and our signature UP blue paint. The polyurethane bushings are a wear item that should be greased and replaced periodically. For track-driven cars, plan to replace the bushings after one racing season; for daily-driven cars, about once a year keeps them performing. Keeping fresh bushings preserves the sharp, quiet response the bars are built to give.

They do different things and pair well. A lowering kit drops the center of gravity and reduces drag, while sway bars directly attack body roll and let you tune front-to-rear balance. Owners chasing flatter cornering often start with the rear sway bar for the biggest felt gain per dollar, then add the lowering kit for stance and a lower center of gravity. Together they transform how the car takes a corner.

Not the way stiffer springs can. Sway bars mainly affect roll in corners, so they flatten the car when you turn without punishing you over straight-line bumps the way a much stiffer spring rate would. Owners report the stiffest setting still keeps daily comfort, since the bar is doing little when both wheels move together. You add cornering control while keeping the everyday ride livable.

You can upgrade risk-free with a 30-day full refund, and the bars carry a 200,000-mile warranty, non-transferable, so durability is not a gamble. That coverage reflects how these were built and validated on record-setting race cars before reaching customers. Note the polyurethane bushings are a maintenance item outside that structural coverage and should be replaced on the schedule above. Driving is believing.

The rear bar is a straightforward bolt-on and does not automatically void your Tesla warranty; under Magnuson-Moss, Tesla must tie a specific failure to the part to deny a claim. The front bar is different in practice, because its subframe-drop install raises the chance of a denied claim, which is why we recommend professional installation and a conversation with our team first. Keep your factory hardware either way.

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.
