Product Details

Tesla Model X / Model X Plaid (2021+) Billet Rear Trailing Arm Set (Lower Aft Link)

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.

      Frequently Asked Questions - F.A.Q.
      Everything you need to know about this product before you buy.

      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 Tesla void my warranty if I install aftermarket parts?

      A vehicle’s comprehensive warranty as a whole may not be voided due to use of aftermarket parts per the Magnusson-Moss Warranty Act (www.sema.org/sema-enews/2011/01/ftc-validates-right-to-install-aftermarket-parts). However, a manufacturer may require a customer to pay for parts and labor for a repair if there is direct causation between a customer’s alteration and the product or service repair being requested. It is in both manufacturer and customer’s interest to follow logic and reason so that the system of good faith is not abused. If this topic interests you please read the law as well as your warranty documentation. Ultimately we are Tesla owners and enthusiasts, we are not lawyers and cannot provide legal advice.

      How can I find a dealer or authorized installer near me?

      To find authorized installers or retailers of Unplugged Performance products in your area, please use the form on our website to provide your location details. This will help us connect you with an authorized installer nearby. You can find the form here.

      What are the shipping options and times?

      Unplugged Performance processes orders quickly, typically within 1–2 business days after placement. For U.S. customers, orders under $50 usually ship via FedEx SmartPost with an estimated delivery time of 2–7 business days. Larger items like body kits or bumpers may ship via freight carriers with curbside delivery; customers will be contacted to schedule a delivery window. International shipping is available to most countries, with shipping costs calculated at checkout. Delivery times abroad vary, generally ranging from 5 to 16 business days depending on destination. Import duties or taxes are the customer’s responsibility. To ensure a smooth shipping experience, provide accurate contact information during checkout. For specific questions or shipping quotes, Unplugged Performance’s support team is available to assist.

      Do you offer international shipping?

      Yes, Unplugged Performance ships to customers worldwide with no restrictions on destination countries. Whether you live in Canada, Europe, Australia, or elsewhere, we can deliver your order directly to your doorstep. We do not charge any additional fees or convenience charges for international payment processing—what you see at checkout is what you pay. Shipping times vary depending on the destination and customs processing, typically ranging from 2 to 6 weeks. Please note that customers are responsible for any import duties, taxes, or customs fees imposed by their country, which are separate from our charges. Orders are processed in the order received, and while made-to-order items cannot be refunded once production begins, defective or damaged shipments are eligible for exchange. If you have questions or need help with your international order, our support team is available to assist you promptly.

      I've been using these coilovers for about two years now and I'm very happy with them. I use my car for daily driving and also at the track. The Sport Pro coilovers do a great job at both places since you can change the ride comfort to stiff or soft. Highly recommend it
