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+)

      My 2022 3 Performance was a monster truck in stock form, wasn't pleased with the look or the softness. A car of this caliber shouldn't look this way and thank goodness Unplugged had the fix. I got their Moderate Springs and they are the perfect amount of drop to daily the car. They eliminate the...

      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...

      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
      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...

      I installed the Unplugged Performance UP INVINCIBLE® HD Rear Bumper with Hardcore Trailer Hitch Receiver on my Tesla Cybertruck, opting for rear rock sliders and LED flood lights, no swing arms. This thing is a beast! Built from tough A36 steel with a sleek black powder coat, it’s perfect for...

      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...

      The shop we had these installed was a 1.5 hour highway drive away so the trip home was a great test to see if we liked them (we live in NC). It was immediately noticeable that the ride of our 2021 Y was softer and bumps were not as hard. We had the shop set our coilovers to setting number "3" and...

      Very quick installation and everyone was great with getting this setup and installed right away. Could feel the difference when driving the car and loved added this to my car. Makes the turns and feel more seamless and have better control as well. Thanks for everything!

      Makes the beastly Plaid more responsive and stable.
      raviprabhakar October 03, 2022
      Same as the fascia, this feels like a must-have Tesla upgrade. The stock Model 3 just doesn’t look the same anymore. I love the dry carbon material and would highly recommend. I wish the diffuser fins came standard, even with a higher cost. With some DIY, you can make the air ducts in the bumper...
