Eliminate the Weak Point on high end builds. Hold 1500Nm+ & 1200awhp.

The factory BMW ATC-13 transfer case is a notorious bottleneck under heavy load. This upgrade completely re-engineers the unit to reliably handle sustained torque, hard launches, and extreme drag/roll racing.

Engineered for Elite Output:

1500Nm+ Torque Capacity: Upgraded clutch architecture expands capacity from 9 OEM frictions to 11 high-coefficient FX-TRT friction clutches and heavy-duty steels.

Built for 1200awhp+++: Engineered alongside a heavily reinforced 4340 billet steel hub (case hardened and nitrided) to eliminate spline failure under maximum launch stress.

Advanced Heat Defeat: Features a completely redesigned internal oiling system with CFD-optimized pathways for aggressive lubrication and rapid cooling during high-load runs.

Easy Fitment: Straightforward, direct plug-and-play installation into the factory location.
