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.

Our pup loves it (to pieces)!
Color: Fox-Crocodile
Fun toy for our playful pup, but nothing indestructible. She finds a seam and in days, the toy is in bits. Lucky for us, she still enjoys playing with parts! Package of 2. One down, one to go!

Holds Up Well
Color: Fox-Crocodile
My dog loves this toy and after several months of heavy use he has yet to rip it apart like he's done with every other toy I've bought him. He has a hard time grabbing it with his teeth to play his usual tug of war games.

Cute
Color: Fox-Crocodile
I love the interactive toys, BUT my dogs are either too destructive or smart because they’ve ripped the little treat part, so I can’t hide stuff in there anymore. Otherwise, they still play tug of war with it. Probably better for smaller or lazy dogs.

Great Interactive Toy for My Dogs
Color: Fox-Crocodile
I have four dogs with different personalities and energy levels, and these toys have been a fun addition to our home. The two dogs in the photos were the first to test them, and they immediately started sniffing, searching, and working to get the treats hidden inside. The toys are soft, well-made, and provide great mental stimulation. I like that they keep my dogs entertained while encouraging them to use their noses and problem-solving skills. The treat compartments work best with small training treats, and the toys have held up well during regular play. Overall, this has been a great enrichment toy for my pack. If you have small or medium-sized dogs that enjoy treat puzzles and interactive toys, I would definitely recommend giving these a try. The two pups in the photos approved them right away, and the other two quickly joined the fun!

Great toy for our mouthy chewing very active dog - he loves it and so do we!
Color: Fox-Crocodile
Great buy! Dog is very mouthy, so got this to try to focus chewing on a toy rather than me, and he loves it. Pockets are a little small for many treats, but they do hold very small ones tucked into each triangle - (16 small treats total between the two toys), and rolls up with a strong velcro which holds pretty well. Dog will forcefully wedge his nose into the roll trying to get to the treats and it doesn't unroll until he works it over. Wasn't positive how well it would hold up - he is a very mouthy puppy who is very strong and likes to shred, but out of all the toys, it has held up some of the best (on par with the kong toys so far) where others are not faring so well. He has pulled and tugged at the eyes, feet and ears repeatedly, and they are still firmly attached and no fraying on the treat spots at this time. He throws this thing around playing by himself and aside from being dirty now being one of his favorite toys, it looks as good as new. The only problem we have had is one of the squeakers no longer squeaks as he seems to have managed to remove that part of the noisemaker - but no holes, no rips, no shreds, nothing else showing wear and tear. He has even used it for tug of war on occasion and though we didn't let that last too long, it showed no signs of tearing or ripping from that either.
