Tesla Model 3 and Model Y Billet Rear Traction Arms and Rear Trailing Arms
-
Upgrade your Tesla Model 3 or Model Y rear suspension with Unplugged Performance’s Billet Rear Traction and Trailing Arm Set. CNC-machined from 6061 forged billet aluminum, each arm weighs under 2 lbs and replaces the factory stamped-steel units and soft rubber bushings with sealed spherical bearings featuring self-lubricating Teflon liners. A military-grade Cerakote ceramic hard coat protects against corrosion and road debris. Plug-and-play fitment that allows you to bolt them on and feel the difference immediately.
- Compatible with 2017–2025 Tesla Model 3 (including Highland refresh) and all Tesla Model Y variants.
- Backed by a 200,000-mile warranty and 30-day satisfaction guarantee.

Product Details
What Do Rear Traction Arms and Trailing Arms Actually Do?
Every time you accelerate, brake, or turn your Tesla Model 3 or Model Y, the rear suspension absorbs and redirects thousands of pounds of force. At the center of that system sit two critical linkages: the rear traction arms and the rear trailing arms. Together, they locate the rear knuckle and wheel assembly relative to the chassis, controlling fore-aft movement during acceleration and braking while maintaining precise wheel geometry through every corner.
In short, they are the structural backbone of your rear suspension. When those linkages flex, deflect, or respond inconsistently, you feel it as vague steering feedback, lazy turn-in, or a rear end that shifts and settles instead of planting and driving.
The Problem with Factory Components
Tesla’s factory rear arms are stamped from steel and use soft rubber compliance bushings. That design makes sense for a mass-produced vehicle: rubber bushings are inexpensive, absorb vibration broadly, and keep NVH low for the widest possible range of buyers. However, rubber introduces compromise. Under hard cornering, heavy braking, or spirited driving, those bushings compress, twist, and deflect, allowing the wheel to move in ways the geometry was never designed for. The result is lost motion at the contact patch, inconsistent toe and camber behavior mid-corner, and a general lack of precision that performance-oriented drivers feel immediately.
Rubber also degrades over time. Heat cycles, UV exposure, and the constant loading of daily driving break down the material, increasing slop and diminishing handling quality with every passing mile.
Why Billet Aluminum Changes Everything
Unplugged Performance’s Billet Rear Traction and Trailing Arms solve every one of those issues through three key engineering decisions.
Forged 6061 billet aluminum construction. Each arm is CNC-machined from a single forged billet, not cast, not stamped, not welded from tubes. This process yields a part that is both stronger and dramatically lighter than the factory steel piece, coming in at under two pounds per arm. Lower unsprung mass means the suspension reacts faster to surface changes, improving ride quality and grip simultaneously.
Sealed spherical bearings with Teflon liners. Replacing the factory rubber bushings with precision spherical bearings eliminates deflection entirely. Force transfers from the wheel to the chassis through a rigid, zero-compliance joint, giving you immediate feedback and repeatable geometry under load. The self-lubricating Teflon lining ensures smooth, consistent articulation over the life of the bearing, while sealed housings keep out water, grit, and road contaminants so daily-driver reliability never takes a back seat to track-level precision.
Military-grade Cerakote ceramic coating. Every arm is finished in Cerakote ceramic hard coat, the same surface treatment used on firearms and aerospace hardware. It resists corrosion, stone chips, and chemical exposure far beyond conventional anodizing or powder coat, ensuring these arms look and perform like new for years of real-world use.
Engineered for Every Driver
Whether your Tesla is a daily commuter, a weekend canyon carver, or a dedicated track machine, these arms deliver a sharper, more connected driving experience with zero increase in noise, vibration, or harshness. Installation is completely plug-and-play with no modifications required, and every set ships with Unplugged Performance’s 200,000-mile warranty because race-proven engineering should never come with an asterisk.

Will upgrading my brakes void the Tesla warranty?
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.
What does the Unplugged Performance product warranty cover?
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.
Will installing Unplugged Performance parts void my Tesla warranty?
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.
