Tesla Model X / Model X Plaid (2021+) Billet Rear Traction Arm Set (Upper Fore Link)
$596.25
Our advanced Model X Plaid suspension development and racing kicked off in June 2021 with our race car Dark Helmet as we set out to develop the ultimate performance handling Model S. The results have followed as we brought home to the Tesla community a Pikes Peak class victory and multiple production based EV lap records with our development race car. In the months that followed, we’ve gone into production with a premium range of suspension components that can be purchased individually or as a comprehensive lineup depending on the goals of each driver. All of our suspension development begins with precision 3D scanning of the car’s suspension to develop a working digital model, then followed by real-world racing and street use internally on our company vehicles before roll out to the public. Our history, race results and industry-leading warranty provide peace of mind that these are the best money can buy.

Find an installer
Will fitting these arms void my Model X warranty?
Not by themselves. Under the Magnuson-Moss Warranty Act, Tesla has to prove that these arms caused a specific failure before denying a claim, rather than pointing to their presence. Our race record and warranty stand behind them. Keep the factory arms you remove and returning to stock is always straightforward if a question arises.
Which Tesla part number does the traction arm replace?
It replaces the rear upper fore link, Tesla part number 1420421-00-D, two per car. This is a direct-fit swap and arrives as a pair so both sides are done together. Ordering against the exact factory number keeps the installation clean with no adaptation required.
What is the construction of these arms?
They are CNC-milled from 6061 aluminum with sealed spherical bushings, and the design is FEA-optimized for static, dynamic, and fatigue strength. That gives a strong, lightweight arm that locates the wheel precisely and runs silently. It shares its build approach with the rest of our Model X rear arm lineup, all developed to survive hard use before public release.
Where were these arms developed and proven?
Through our Model X Plaid suspension program, which kicked off in June 2021 with the ‘Dark Helmet’ race car. That effort brought home a Pikes Peak class victory and multiple production-based EV lap records. Every arm starts as a precision 3D scan of the car’s suspension, then gets validated through real racing and street use on our own vehicles before it ships. This is race-tested hardware.
Can Unplugged Performance install the traction arm set?
Yes. Our Hawthorne team can fit these and verify the rear alignment afterward; request a quote on the product page. They ship the next business day, so the wait is short. If you are outside Los Angeles, any shop familiar with the Model X rear suspension can perform what is a direct-replacement job.
