VTT Billet DUAL POINT G8X Diff Lockdown Kit
Serious traction starts here.
VTT is proud to introduce the Billet DUAL POINT G8X Diff Lockdown Kit—a must-have upgrade for high-performance G80 owners. The factory differential bushings are notoriously soft, allowing excessive diff movement that robs you of traction and stability.
As the G8X platform continues to push performance boundaries, the OEM components reveal their weaknesses. One major flaw? Significant differential deflection under hard launches, often resulting in broken rear bushings—a growing issue in the community.
💡 Our solution:
What BMW should have done from the start—a true DUAL-POINT Lockdown System that secures the differential at four key locations:
-
Precision CNC-machined billet pucks at the lower differential mounts
-
Matching billet pucks at both secondary subframe points
This setup locks the diff down completely, eliminating unwanted movement and dramatically improving stability under launch and aggressive driving.
🛠️ Easy Installation:
No subframe or diff removal required! Just drop the exhaust and heat shielding for access. A straightforward, no-hassle install.
⚠️ PLEASE NOTE:
NVH Disclaimer:
All products designed to stiffen or reduce drivetrain movement inherently have the potential to increase NVH—Noise, Vibration, and Harshness. While these bushing inserts typically add minimal NVH, results may vary depending on your vehicle and personal sensitivity. This product was specifically engineered to minimize drivetrain movement. Returns due to NVH will not be accepted once the product has been installed.
Exhaust Clearance Notice:
This product may require exhaust system modifications. Depending on your exhaust brand, fitment, and layout, adjustments may range from minor to significant.
-
VTT is not responsible for any necessary exhaust modifications.
-
Vehicles using the stock G8X exhaust will almost certainly require modification.
Returns due to exhaust clearance issues will not be accepted once installed.
