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.

      On the track or not these sway bars make your car feel solid on turns. Immediately I noticed improved corner turns which is great! Highly recommend!
      jesus.ruiz.2389 February 02, 2023
      I absolutely love this coilover setup. The build quality out of the box looked so great, heavy duty, well made, and absolutely beautiful. It takes the Model 3 Performance handling to a whole new level. It feels planted, quick, and incredibly responsive through corners. When paired with a good set of...

      Bryan L. December 05, 2025
      This is by far the best front fascia out there and its makes the Model 3 look so much better! It gives it a much sportier look and I get comments on it all the time. One of the simplest upgrades that makes a huge difference as far as the look of the car goes. Couldn't be happier with how it looks....
      thecliff03 October 16, 2023
      I put these beautiful gloss BBS Flugplatz wheels on my performance model 3 with 255/35/r20 Yokohama tires, and took it to the track at Buttonwillow. The car handled so well, was planted solidly and super smooth. I was blown away how easy it was to drive, and just how well the car turns in even...
      Sof October 19, 2022
      Incredibly well tuned for the Model 3. My car is completely flat and on rails through every turn. Very firm in all settings yet still just comfortable enough to daily drive in the first 4 clicks with the oil bypass feature. Super easy to adjust back and forth from weekend driving to daily driving....
      Andrew P. November 03, 2022
      A perfect look on the UP-03 wheels I got for my model 3!
      Frank August 09, 2023
      Makes the beastly Plaid more responsive and stable.
      raviprabhakar October 03, 2022
      Been riding with these coilovers for a year now on my 2020 Model 3 which is my daily driver car from home to work. I have a 2 inch drop with medium damping settings, makes the car handle and feel like a true high performance luxury vehicle. Thank you Kirk and UP team!
      Mason October 31, 2025
      Having the moderate version installed soon and I am very excited for this upgrade, how it is going to look and how it will feel on my Model 3!
      Christian N. January 01, 2026
      I recently installed the Unplugged Performance Rear Sway Bar Upgrade on my Tesla Cybertruck AWD, and the improvement is incredible! The 3-way adjustability allowed me to dial in the handling perfectly, and I chose the middle setting for a great mix of daily comfort and sporty performance. The...
      twaller2 August 09, 2025
      I was not going to get these, as I do not track my car. I love the any chance to control as much about my car as possible. Just one more way to stand out from the crowd. And, I can get my tires to last a reasonable amount of miles.
      deeidson November 16, 2022
      Psychologists say that the more you pay for something, the more you like it. Maybe that’s what’s happening here, but the front fenders are now my most cherished upgrade. I love that I can unlock up to a 315mm square setup with a track camber and 305-295mm with a daily camber. I’ll never be...
      David S. November 15, 2022
      It's incredible to me that my Plaid shipped with such small, inappropriate stock brakes. It was one of the first things I noticed. Unbelievable acceleration, very poor stock braking. Enter Unplugged Performance - I upgraded the fronts to these carbon ceramic much bigger brakes, and then headed to...
      mike September 27, 2022
      Peace of mind for the wheels to stay protected.
      Christian N. December 12, 2025
      These nuts are awesome! So much lighter than the OEM and they look so much cooler. Reduces unsprung weight while looking cooler which is a win-win. I went with the burnt titanium finish which looks incredible and really adds some color to your wheels in a subtle way. Highly recommend.
      zackfeldstein9 September 07, 2022
      One of my favorite upgrades to the Model 3, allows for fine-tuning of the entire suspension system to balance the car out. Each notch makes a noticeable difference, so certainly flexibility with the settings. I started with Medium/Medium settings and tuned them according to the car's handling.
      Shimmy October 23, 2024
      I got the FUCAs installed on my 2018 Performance Model 3 and wished I hadn’t waited so long to do it! Now I can do proper alignments with camber on the front, not possible to do with the stock control arms. You can also put custom wheel sizes with super wide tires on the front without worrying...
      Sof October 18, 2022
      So this review is based off of two things, product: how well it performed and customer service. So with the pre-yoke model s and x, they’re known for their shutter issue and tire wear, so to fix this, I torn between the links from native or UP. So I decided to go with UP, I got the complete kit...
      quimai25 October 19, 2022
      short and simple ... NIGHT and DAY difference when turning in and out of turns and really felt as if the car was on RAILS.Had a track day at Chuckwalla Valley Raceway and when going through its famous "bowl" Turn 13 I felt planted and gave me confidence to push it more lap by lap. Overall best...
