Tesla Model 3 and Model Y Billet Rear Traction Arms and Rear Trailing Arms

A Backstory From 2017:

Our Billet Rear Traction and Billet Rear Trailing Arms are designed by drivers for drivers. Our original full billet rear arm set (rear camber, rear toe, rear traction and rear trailing arms) traces an origin back to the early days of TeslaCorsa in late 2017. In fact the first car of ours Randy Pobst was involved in development feedback was utilizing an early version of these rear arms. While our rear camber and toe arms have, seen public release and won over driving enthusiasts worldwide, we’ve been admittedly slow to finally offer a public release of our rear traction and trailing arms. The wait is now over and these recently revised next generation UP rear arms are finally perfected for public release. Our unparalleled history of street and race Tesla Model 3 upgrade development is utilized in the design and rugged specifications to ensure these are perfect for daily driven high milage cars as well as purpose built race cars. Prior to public release we’ve set multiple lap records in multiple countries using these arms and we’re pleased to finally offer them for wider release!

Daily Driver and Race Cars Perfected – Handling You Can Feel

The UP Billet Rear Traction Arms and Billet Rear Trailing Arms can work in conjunction with a fully stock suspension or a fully-upgraded suspension to road feel and ultimately handling. All driving enthusiasts unanimously agree that getting direct feedback, and crisper response with less slop is a great thing. With a Tesla in particular, a key design factor is achieving this without increased NVH (Noise, Vibration or Harshness) problems. As a result of this desire, many high end cars utilize sealed spherical bearings for this very purpose in their suspension. The Model 3 happens to have more slop in the factory rubber bushings than we prefer and as a result we created this original product in 2018 and have since then evolved it into the current generation.

Factory+ Reliability and Unrivaled Construction Materials:

We built every set out of the best materials, we finish them in the most durable finishes and we equip them with the most premium bushings money can buy. Specifically this means we utilize forged 6061 forged billet which we precision machine in Los Angeles, then we utilize military grade clear Cerakote ceramic hard coating finish to showcase the natural billet and we pair them with a premium car manufacturer’s sealed spherical bushings that are proven to be reliable for hundreds of thousands of miles. Just like the rest of our suspension which is daily driven tested, raced on and (unfortunately) even crash tested at Pikes Peak, all of our products stand the test of time and carry an industry leading warranty to back it up.


When used in combination with Unplugged Performance Coilovers, Billet Adjustable Rear Camber Arm Set V3Billet Adjustable Rear Toe Arm Set V3 (Model 3 / Model Y) and Billet Height Adjustable Rear Spring Arms – Ultimate Edition, our Billet Rear Traction Arm Set (aka Upper Fore Link) and Billet Rear Trailing Arm Set (aka Lower Aft Link) complete the ultimate rear suspension set up for any Tesla Model 3 or Tesla Model Y.

Don’t take our word for how our cars handle with these, ask any UP client or take a few minutes and watch below as we win over an historically harsh Tesla critic Matt Farah with the driving performance of our Ascension-R (these arms were fitted on that car for the video shoot):

Construction Details:

  • CNC-milled 6061 forged billet aluminum for superior strength while being weighing under 2lbs each (lighter than the thinner stock stamped steel)
  • Sealed spherical bushings for maximum durability and enhanced road feel and handling
  • Self-lubricating Teflon lining for a quiet and maintenance-free lifetime use
  • Anodized hard coating to maintain the beauty of the billet aluminum milling for years to come
  • Install out of the box, with no adjustments
  • Made in the USA

30 Day Money Back Guarantee

All of our suspension products are designed to perform flawlessly and to impress. We offer a 30 day no questions asked money back guarantee to stand behind our quality and performance.

200,000 Mile Warranty

These are designed to last longer than your car. To put a number on it, we will warranty these for 200,000 miles (non-transferable).
