If I correctly recall with 2 o-rings on each outdrive, it would cause issues, but no problems with 1 per side. I built mine with only 1 o-ring per side and had no problems. However, since installing the MIP diff, I'm not running any o-rings at all and have no issues, and my BF runs a brushless 17.5.

Looks great!

Installed the brushless motor a short while ago and gave the BF a good run. Compared to the stock silver can, it obviously has more power everywhere and more top end. The MIP diff was flawless, the transmission handled it beautifully. This is definitely a fantastic upgrade to the ORV. I'm very happy with how it worked out. IMO, this is as close to a must upgrade as you can get for these vehicles.

The BF and MB gearbox is held together by two metal plates that are rather soft metal. The diff is a bevel gear unit that is held together by said metal plates. Under load the plates tend to flex outward, lessening the pressure that holds the diff together. When that happens, the diff gears start to grind. You'll hear a very distinct "clicking" sound. Eventually the gears give out. The MIP diff is a self contained, ball diff unit that eliminates all of that and turns the transmission of the BF and MB into a "modern" style transmission with no more diff worries. Hope this helps. Cheers and Merry Christmas.

The MIP diff for my 2016 BF came in today. It's been installed and tested. After the install, I gave the BF an agressive run and the diff worked flawlessly. It also has a very smooth diff action. So just for giggles, I put it on the carpet, gave it a slight push back and hit full throttle. The BF immediately popped a wheelie that almost flipped it over until I let go of the trigger. No noises, chatter, clicking or anything associated with the stock unit. Assembly is very easy and straight forward, especially if you are familiar with AE diffs. I'm running a Tekin RS ESC and Thunder Power 5300mAh 2s LiPo driving the stock silver can, lol. A 17.5 brushless that's around here will soon replace the stock motor. Thanks again to Pintopower for his perseverance and to MIP for producing it. The ORV can now have a solid, "modern" transmission.

Here's a pic of the assembled diff next to the included flanged bearings.

Same here. Just checked my email a minute ago. Message from MIP saying the diff has shipped!

Yes, I saw the fleabhey hex kit, but didn't like it, I know what you mean by needing a thrust bearing. Right now I'm looking at the RPM Revolvers, which seem to fit fine looking at the description. I'll try those Revolvers and keep trying to get HPI fronts until a better solution presents itself. Joel

Hi all, I'm looking for a second set of wheels for my re-re BF. The RPM Revolvers look like good wheels and HPI makes a mounting adapter for the rear, but I'm not sure on the fit for the front and the offset. Has anyone tried or know if these will work on the BF? Thanks. -Joel

I think a good mod/upgrade would be a 12mm Hex conversion for the front axle, similar to the Associated front axle on their B4 2wd buggy. That would open a great amount of wheel choices for the ORV. All the HPI 2.2 wheels (and many others), which I can only seem to find for the rear would be mountable in the front end.
