Description


Upgrade your G8x M2, M3, or M4 (RWD or xDrive) with a precision engineered differential solution built for track enthusiasts who demand reliability, efficiency, and peak performance. The MMX High-Capacity Baffled Differential Sump is designed to keep your drivetrain running cooler, better lubricated, and more stable under aggressive driving conditions.

Maximum Oil Capacity, Cooling, and Stability

This upgraded sump increases differential oil capacity by up to 2 liters (2.10 quarts), ensuring consistent lubrication even during extended high G cornering. An integrated billet windage tray keeps the gears and pinion continuously supplied with oil while reducing internal drag.

Both internal and external cooling fins significantly increase surface area for heat dissipation, stabilizing differential temperatures and supporting reliable performance on track or road.

Engineered for Strength, Precision, and OE-Level Fitment

Each sump is CNC-machined from 6061-T6 billet aluminum, offering exceptional strength without unnecessary weight. Every surface and feature is engineered for long-term durability and a flawless seal.

This is a direct OE-style fit, requiring no modification and installing seamlessly to factory mounts. Compatible with the MMX Dual Differential Mount (MMR55-1606) with no additional hardware required.

Eliminates Common G8x Track Issues

Helps prevent the “Rear Axle Differential Lock: Driving Stability Limited” warning, allowing more uninterrupted track time.

External Cooling Ready

Includes an additional -8AN port and M22 to -8AN adaptor for external cooler integration on higher-demand builds.
