VTT A9X Supra/BMW Z4 / G2X / G42 Billet Diff Lock Down Kit

VTT noticed a hole in the VTT A9X Supra/BMW Z4 / G2X / G42 Billet Diff Lock Down Kit market for a high-quality, lightweight, NVH-friendly, and easy-to-install Diff Lock Down kit to improve diff stability under launching, and hard cornering. So we did something about it and went to work on a very innovative design that 100% positively locks the diff down from movement, while shielding it from adding a ton of NVH, and can be used with the stock diff, and subframe bushings. This design uses existing mounting points on the vehicle, you do NOT have to remove the subframe or the Diff to install. Simply remove 4 diff bolts, drill two holes in the subframe slightly bigger, install two M10 riv-nuts, and install the lockdown, you do not even have to move the exhaust. A typical install can be 15-30 minutes for someone who is experienced working on vehicles, an hour if you like taking it slow. You WILL need a Riv-nut tool to install the Riv-nuts, we provide a link below for what we recommend on Amazon.

Features:

  • Lightweight 1.5 lbs for the entire lockdown plate
  • Uses FOUR connection points on the Diff, and two on the subframe for the ultimate in positive diff location, this will stop all diff movement on launch, saving your guibos, etc
  • 100% Billet construction from 6061-T6 aluminum
  • Anodized in 4 colors for corrosion resistance, a long-lasting finish, and good looks
  • The subframe does NOT have to be removed for installation
  • Uses all 12.9 grade hardware
  • Does not add excessive NVH
  • Positively locks down the diff to eliminate all unwanted movement under launches, acceleration, cornering, etc.

All products that are designed to stiffen or reduce drivetrain movement inherently have the tendency to increase NVH or Noise, Harness, or vibration. While these bushings inserts have been found to add little NVH in most instances. Your results and sensitivity to NVH may vary. This product is designed to reduce drivetrain movement, and that was the goal when designing and manufacturing this product. Returns for NVH are not accepted once products are installed.

VTT A9X, G8X, G42, G2X Rear Bushing Insert Kit

Want to tighten up the rear differential on your 2021+ G8X M3/M4, A9X Supra, G42 2 Series, or G2X BMW and eliminate unwanted differential movement during hard launches? VTT has you covered with our Rear Billet Differential Insert Kit.

This precision CNC-machined billet insert is designed to press into the factory rear differential bushing, filling the voids in the OEM rubber bushing to dramatically reduce differential movement under load. By reinforcing the factory bushing rather than replacing it, the kit maintains the majority of the stock ride quality and comfort while improving drivetrain stability, launch consistency, and power transfer.

Installation is simple. Support the differential, remove the factory rear differential bolt, and use the factory bolt to press the billet insert into place. Once installed, replace the factory hardware with the supplied upgraded bolt, washers, and lock nut.

VTT Billet BMW Transfer Case Bushing Inserts

Stop the Flex. Launch with Confidence.

Soft bushings are the enemy of hard launches and drivetrain longevity. The factory BMW transfer case bushings—especially on the G8X and F9X platforms—are notoriously soft. That’s the last thing you want when you’re putting serious power down.

Sure, you could replace the entire bushing with a solid one, but that often requires lowering or removing the transfer case—not to mention the added NVH (noise, vibration, and harshness) that comes with it.

Our transfer case bushing inserts offer a smarter solution: reduce bushing flex without sacrificing comfort. You keep smooth, quiet drivability around town and at idle—but when it’s time to launch, the transfer case stays planted.

Fitment Notice – Two Versions Available:
BMW uses two different transfer case bushing types. We now offer Version A and Version B inserts to match.
⚠️ You must physically inspect your vehicle’s bushing to determine which version you need.
We are not responsible for incorrect orders if this step is skipped.

Warranty: 12 Months
