Tesla Model 3 and Model Y Billet Rear Traction Arms and Rear Trailing Arms

Each arm is CNC-machined from a single piece of forged 6061 billet aluminum and comes in under two pounds, lighter than the stamped steel factory unit. That drop in unsprung mass lets the suspension react faster to the road, which helps both grip and ride. The construction is stronger than stock while shedding weight, so you are not trading durability for the reduction.

The arms use sealed spherical bearings with self-lubricating Teflon liners in place of rubber bushings. The liner keeps articulation smooth over the life of the bearing, and the sealed housing keeps out water and road grime. On top of that, every arm wears a military-grade Cerakote ceramic hard coat, the same kind of finish used on firearms and aerospace parts, to resist corrosion and stone chips. Daily reliability was a design target, not an afterthought.

No. Swapping rubber for spherical bearings removes deflection and gives immediate feedback, but UP tuned this set to add no increase in noise, vibration, or harshness. You get sharper, more repeatable geometry under load without the drone that sometimes comes with solid joints. Owners run these on commuters and track cars alike.

Yes. You can order the full billet rear traction and trailing arm set, the traction arms only, or the trailing arms only. That flexibility helps if you are building the rear suspension in stages or already replaced one pair. Many owners pair these with the front lower control arm spherical bushing set to firm up both ends of the car.

A sway bar or brace reduces body roll and flex, but neither addresses the compliance built into the rear suspension links themselves. These arms attack the source: the rubber bushings that let the wheel wander under load. Fit them alongside the adjustable front and rear sway bar end links and you get both stiffer roll control and a rear end that holds its geometry. They solve different problems, so they complement rather than replace each other.

They carry a 200,000-mile warranty and a 30-day satisfaction guarantee, which tells you how UP views their durability. Installing them will not automatically void your Tesla warranty either; under Magnuson-Moss, Tesla must prove an aftermarket part caused a specific failure to deny that portion of coverage. Keep your stock arms in case you ever want to revert.

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.
