Tesla Model S / Model S Plaid (2021 – 2026+) Billet Rear Trailing Arm Set (Lower Aft Link)

Our advanced Model S 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.

Billet Rear Trailing Arm Set (Lower Aft Link)

These Unplugged Performance Billet Rear Trailing Arm Set (Lower Aft Link) for Tesla Model S Plaid and LR 2021+ vehicles replaces the standard Lower Fore Link with a stronger and lighter billet aluminum version with high performance sealed spherical bushings.  The upgraded bushings provide both silent operation and improved handling feel and durability. The new 2021+ Model S features an all-new 5 link rear suspension that we have precisely re-engineered for performance driving.

  • CNC-milled 6061 aluminum for maximum strength while saving weight
  • FEA-simulation optimized to ensure superior static, dynamic, and fatigue strength
  • Sealed spherical bushings for unmatched precision and durability with silent operation
  • Replaces Tesla part number RR LOWER AFT LINK, P2 1420452-99-C
  • We recommend pairing this item with our full suite of rear suspension products for your vehicle:
    • Billet Adjustable Rear Camber Arm Set (Fits Model S/X 2021+)
      Billet Adjustable Rear Toe Arm Set (Fits Model S/X 2021+)

      I opted to get the race spec coilovers since I track the car. I’m very pleased with the performance of the coilovers. Not to mention the ride height is exactly what I was looking for. Thanks to the Unplugged team for their willingness to assist and answer my questions. They are very...

      Beautiful wheels. These have the most style. The black matches perfectly with the blue. To complete the look, add the super light titanium lug nuts and the carbon ceramic front big brake kit, as shown in the picture.
      raviprabhakar October 03, 2022
      Yes, it did improve the comfort of the 2022 model Y dramatically, I will keep my Y for many years. I also switched to an 18" wheel/tire and that helped too...
      Alex M. December 13, 2025
      This brace was an amazing upgrade for my car. I added the UP rear sway bar first then the full UP suspension then this Strut Tower Brace. I feel this completed the feel i was looking for. The cars back end feels so solid while cornering and over the bumpys feels so solid too. A noticeable...
      Chad J. May 15, 2024
      This is a necessary product if you want to properly raise or lower your vehicle. Part is super high quality.
      josephschneider77 November 04, 2022
      An absolute MUST when thinking about your first upgrade. The Model Y, even in it's Performance Model, has more body roll than you'd like. It was one of my biggest complaints when driving the first few months. After installation, body roll was greatly reduced. Cornering on-ramps and turns with a...

      Dominic Marcu - Racing Driver Just perfect for my car
      Dominic M. April 12, 2023
      This spoiler has a perfect balance. It isn't as subtle as the OEM performance Teslas, yet not comically large. A fitting addition to the Plaid! Great design as is to be expected from Koenigsegg. Slight efficiency gains at high speeds as well.
      Ravi October 03, 2022
      Dominic Marcu - Racing Driver perfect! with their help I can have the desired setup for the competition car. the car becomes more rigid and stable
      Dominic M. April 12, 2023
      These wheels are insanely light and strong! And, they look the bomb! If I didn’t look while picking them up, I would have thought they are carbon fiber! The same spec as was originally used on the Bionic Phoenix Model 3 race car! I put in my fastest time at Buttonwillow on these wheels running...
      Sof October 03, 2023
      Should’ve been stock with all teslas, combined with a stiffer set of aftermarket coilovers, the car handles insanely well. I purchased this front and rear sway bar set along with end links for a standard range model 3. It makes such a huge difference, the car feels more planted especially entering...

      Finally!!!! Been waiting on UP to both have a decent Black Friday sale and to have this item on it and whatdoyaknow…..HALF OFF! I wish it was all gray everywhere, but I’ll do the touch up myself and get it 100% how I need it!!!
      Montage Ø. November 07, 2025
      My Model Y's overall ride quality and handling performance SERIOUSLY improved after getting this sway bar set installed! I can't get over how much more fun my Model Y is to drive now. I was so excited to put these to the test after getting them installed. The very next day, we went on a road trip...
      James_M September 05, 2022
      The Air suspension upgrade kit works well on my refreshed Raven Model X with the upgraded Air Suspension kit. The suspension setting on Low not only improves the look but also benefits from higher efficiency with the advantage of location based auto raise function....
      f1dinesh August 15, 2023
      Nice looking badge to represent the 7k I spent on the Cybrhex wheels. As a matter of fact I need another!
      Montage Ø. November 07, 2025
      My only complaint is the FSD doesn't work with this on, which renders it useless to me.
      Taxxman December 10, 2025
      Who likes shredded tires? Nobody! Fix the wonky camber on early Model S vehicles with this easy upgrade.
      bluetrevian March 20, 2024
      I installed these with the race pads.. The car is significantly better at stopping, the pedal feel is fantastic. One of the biggest addtional things I noticed was the decreased weight.. The wheels done thud as hard over bumps, and comfort setting now feels like actual comfort.. The wheels also...
      Robert M. October 10, 2022
      Really nice jacket. A must have for a UP enthusiast!
      Montage Ø. November 12, 2025
      I'm currently putting together my custom UP INVINCIBLE® kit from Unplugged Performance with the help of Frank, and the transformation is insane. The lineup includes the HD Front Bumper with the optional 11-inch LED light bar that absolutely lights up the night, the bulletproof Heavy Duty Rear...
