BMW E31 E32 E34 DCT / 8HP Swap Billet Transmission Crossmember

Stop fighting with fabricated brackets and hacked-up OEM crossmembers. This precision-machined billet crossmember is purpose-built for mounting modern DCT and 8HP transmissions in the BMW E31, E32, and E34 chassis. CNC machined from solid 6061-T6 aluminum and hard anodized black, it's engineered to handle the torque demands of serious engine swaps while bolting directly to the factory mounting points.

Transmission Compatibility:

• Getrag 7-Speed DCT (GS7D36SG / "DCT")
• ZF 8HP (8HP50, 8HP70, 8HP75, 8HP90)

Fitment:

• BMW E31 (8-Series, 1990-1999)
• BMW E32 (7-Series, 1988-1994)
• BMW E34 (5-Series, 1989-1995)

Adjustable Design

Slotted chassis mounting holes allow front-to-back adjustment to accommodate different adapter plate thicknesses and chassis variations. Whether you're keeping your M30 or M50, swapping in an S85, S62, N54, LS, or any other combination, you can dial in precise crossmember positioning for proper driveline angles.

Material & Construction:

• 6061-T6 Billet Aluminum - Machined from solid billet for maximum strength and rigidity
• Hard Anodized Black - Type III hard anodize for superior wear and corrosion resistance
• CNC Machined - Precision tolerances for accurate fitment

Key Features:

• Adjustable Position - Slotted mounting holes allow front-to-back adjustment for various adapter plates and swap configurations
• Universal Trans Mount Compatible - Works with OEM and aftermarket OEM-style transmission mounts
• Direct Bolt-In - Uses factory crossmember mounting points
• Engine Agnostic - Works with M30, M50, S85, S62, N54, LS, and other swap combinations using DCT or 8HP transmission
• Lightweight - Billet aluminum construction reduces weight vs. steel fabricated alternatives

Why Upgrade?

Modern DCT and 8HP transmissions offer massive performance advantages - faster shifts, better efficiency, and higher torque capacity than anything originally fitted to the E31, E32, or E34. But mounting these transmissions properly requires a crossmember designed for the application. The OEM crossmember was never intended for these transmissions, and fabricated solutions often compromise strength or adjustability. This billet crossmember solves both problems - it's stronger than steel fabrication at a fraction of the weight, and the adjustable design means you can fine-tune your driveline geometry regardless of your specific swap setup.

Installation Notes:

Bolts directly to factory crossmember mounting locations. Slotted holes allow front-to-back positioning adjustment during installation. Compatible with OEM and aftermarket OEM-style transmission mounts (sold separately).
