8HP51 Billet P2 Carrier (DMS-5807)

The Dodson 8HP51 Billet P2 Carrier (DMS-5807) is a one-piece billet replacement for the OE planetary carrier in the ZF 8HP51 transmissions. It suits high-horsepower BMW, Toyota Supra, Jaguar, RAM, Jeep and aftermarket 8HP swap builds where the factory P2 carrier becomes a known limit.

OEM Applications

The 8HP51 ship from the factory across a wide range of platforms, including:

• Toyota GR Supra A90/A91
• BMW G20 3 Series, G22 4 Series, G29 Z4, G30 5 Series
• BMW X3 and X4 M40i
• Jaguar XE (restyled first generation)

Most Advanced 8HP Components on the Market

Dodson 8HP components are the most technologically advanced on the market. Our components for the 8HP platform draws on decades of experience in world record-breaking dual-clutch builds and brings that same engineering pedigree to the 8HP platform.

One-Piece Billet Construction

Dodson precision CNC machines the DMS-5807 from a single piece of superior alloy. Increased wall thickness raises torque capacity over the OE carrier. The result is a stronger, stiffer carrier without the rotational inertia a heavier strengthened assembly would normally carry.

The billet upgrade removes the need to run a welded OE assembly for added strength. Many high-horsepower 8HP builds previously relied on welding the factory carrier to survive the loads. DMS-5807 replaces that work-around with a purpose-built billet component.

Stiffness Without Inertia Penalty

The Dodson upgrade increases stiffness without penalizing rotational inertia. The result is a stronger transmission internal without compromising shift response or acceleration feel. Workshops install the 8HP51 Billet P2 Carrier during a standard 8HP rebuild across OEM and swap applications.
