BMW 8HP AWD to RWD Conversion Kit

A complete, high-quality solution for converting 8HP BMW AWD transmissions (8HP70X and related variants) to a RWD configuration.

The HPR 8HP AWD to RWD Conversion Kit is engineered with practicality and performance in mind.

Unlike many alternatives on the market that require modification or clearancing to fit within the transmission tunnel, this kit features a compact design with repositioned outer mounting point on the left side. This ensures improved clearance and a straightforward installation.

In addition to the conversion components, the kit includes our full UltraFlex rear mount system. This comprises durable bobbin mounts (Shore 60A) along with all necessary hardware, delivering excellent vibration control and drivetrain stability. The UltraFlex mount is also fully compatible with all HPR chassis-specific crossmembers, ensuring seamless integration across a wide range of builds.

The flat-profile bobbin mounts in the Ultraflex kit simplify custom crossmember fabrication, saving time while ensuring precise fitment.

The UltraFlex mount adjustability makes it easy to precisely dial in your drivetrain angles, which is critical for a successful swap without any vibration/NVH issues. 

(See the HPR Pro Tip in the installation guidelines for more details.)

Designed to offer both flexibility and value, this package combines premium engineering with competitive pricing, making it one of the best-value solutions available.

Great Tray For Storing My Everyday Carries
Size: 8.5" x 5.8" x 1.9", Color: Black
My everyday carry items (wallet, keys, etc.), used to just get thrown around wherever when I'd get home, but this little tray makes a great, defined, space for me to keep those things when I don't need them on me. The soft lining reduces the obnoxious sound of throwing keys on a hard surface, and of course keeps me from scratching up a surface. The build feels quality and I haven't seen any damage to it yet. Also the all black version with gold buckle looks quite good and adds a subtle touch of luxury. Absolute recommend for the price.
