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 bought my spoiler as soon as my new Model 3 2021was delivered to Vancouver in March 2021. A friend of mine had suggested getting this one specifically and when we added it to my new white Tesla with its dark glass roof-and my extra tinted windows this Black Carbon spoiler added a perfect finishing...

      Makes the beastly Plaid more responsive and stable.
      raviprabhakar October 03, 2022
      My 2019 Performance Model 3 is great, but with the heavy weight of this EV the cornering at high speeds was disappointing. I recently added these Dual Rate Lowering Springs to the UP Sway Bars, and the handling is definitely getting better! The initial spring rate makes the bumps less jarring with...

      Looks great, performs great. If you track this is a must have. Get tons of compliments on the looks too.

      Edgar August 28, 2023
      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...

      Dominic Marcu - Racing Driver Just perfect for my car
      Dominic M. April 12, 2023
      I love the front ascension fascia! Really changes the whole look of the Model 3. My least favorite part of the car was the front bumper and this changed it all for me. Noticeable improvement in downforce as well which is a nice touch. Totally transformed the car and I couldn’t be happier. Also...

      Product is top notch when I installed them it was like switching from a 1 piston sliding caliper to a bbk. Also cold performance and noise are really good
      Christos K. November 04, 2022
      I got this installed about 2 years ago and everything is perfect! This really makes my car's interior complete instead of having a plastic headliner. Every time another Model 3 owner looks inside my car, that is definitely the first thing they noticed. Also the guys who worked on my car were super...

      I went with the 30mm spacers just to give the Cybertruck a slightly wider stance. These are very well-built. I have put almost 2,000 miles on the truck since installing the spacers and couldn't be happier. The driving dynamic did not change noticeably and I have not noticed a significant reduction...
      Josh H. December 09, 2025
      The sway bars are phenomenal. I installed these in my 2025 model 3 performance. I already had the moderate lowering springs from unplugged and after adding the sway bars and the end links made a massive difference. There's barely any body roll and the car feels more planted even when heavy...
      mauricio p. April 27, 2025
      Getting these installed along with the moderate version of the dual rate springs on my Model 3! Very excited and I cannot wait to see the new look and feel the significant difference.
      Christian N. January 01, 2026
      I purchased the camber and toe arm set my Tesla Model X Plaid. The primary purpose of buying these arms was to reduce the inner tire wear. These arms are well engineered, beautifully crafted and built solid. I highly recommend these products made by Unplugged Performance. The craftsmanship of the...
      f1dinesh August 07, 2023
      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
      Installed traction and trailing arms on 2024 Model 3 Performance, keeps the rear end more stable, especially on hard acceleration and deceleration at the track.
      Shimmy October 23, 2024
      Worth every penny. The iron BFB is one of my favorite things I’ve done to my car so far. Brakes are one of the most important things on a car and I notice such an improvement with these over stock brakes. On track I am able to brake much later into corners and the brakes have basically zero fade...
      zackfeldstein9 September 23, 2022
      Had UP install the HD front bumper with the 11" LEDs. Robust steel construction, makes the truck look more aggressive but lines remain clean. This bumper is what Tesla should have equipped the truck with out of the factory! LEDs are super bright as well. Simply the best looking, best designed,...

      Unplugged Performance UP Emblem You can see my photos under Steve Guevara. The UP Emblem, just another seemingly innocuous item that KIRK added to make the car pop when driving behind it. The sun shines on the titanium and it screams at you and then goes back into its subtle way. To say that I love...
