$458.10
Hurry Low Stock

If you're looking to tighten up the handling on your Audi or VW, the 034Motorsport Rear Trailing Arm Spherical Bearing Upgrade Kit is a game changer. This isn't just another upgrade; it's a serious step up from those squishy factory rubber bushings that can leave your rear end feeling loose and vague, especially when you're carving through corners or hitting uneven pavement.

Let’s be real: those stock rubber bushings are a bit of a letdown. They flex under load, which can mess with your suspension geometry and lead to that dreaded understeer. You know the feeling—when you're in a turn and the back end feels like it's floating. Not ideal, right? This kit swaps out those rubber bushings for motorsport-quality Aurora Spherical Bearings. These bad boys don’t deflect, giving you precise handling and a road feel that’ll inspire confidence every time you hit the gas.

What makes this upgrade stand out? For starters, spherical bearings let your suspension articulate freely without binding, completely eliminating that annoying slop you get with polyurethane bushings. Plus, this kit comes fully assembled with new factory steel trailing arms, making installation a breeze—just bolt it in and go! Here’s a quick rundown of what you get:

  • Fully assembled with new factory steel trailing arms—easy bolt-in installation!
  • Genuine Aurora Spherical Bearings with Teflon race lining for smooth operation
  • Billet aluminum bearing holders, anodized in sleek black
  • Stainless steel bearing spacers for durability
  • Improved handling and road feel you can actually notice
  • More precise and predictable handling, perfect for spirited driving
  • Fully rebuildable, so you can keep it going strong

Now, let’s talk fitment. This kit is designed for:

  • 2015 - Present Audi A3/S3/RS3 (8V/8V.5 - MQB)
  • 2016 - Present Audi TT/TTS/TTRS (MkIII - MQB)
  • 2015 - Present Volkswagen Golf/GTI/R (MkVII - MQB)

It directly replaces the following part numbers:

  • 5QM505223 / 5QM 505 223
  • 5QM505224 / 5QM 505 224
  • 5Q0505541A / 5Q0 505 541 A

One last tip: after you install this upgrade, it’s a good idea to get an alignment back to factory specs. Trust me, your car will thank you.
