I heard Brett Tilkei is running gear diffs in his but not sure how he got them in there next time I see him ill ask.

He was probably running the Durango ones since they fit almost perfectly, unless there prototype's that he's testing.

This is what he used

Yeah I'll stick to a ball diff at that price. I hated how much I have to rebuild mine but never mind.:/

with the gear diff it would be much heavier than the ball diff and you would have to re-adjust and tune suspension etc. It is a great tuning option and something different in which excels this hobby sport of ours.

Having used the gear diff conversion for the last few months, initial results are great. On med-high to high traction surfaces it definatly shines. Forward traction/bite and acceleration out of corners is a major benefit. Also through high speed sections like sweepers its very consistent. I've found the car more responsive to throttle inputs mid corner and once it's squared up out of the corner you can just pull the trigger and the acceleration is explosive. Brakes also feel a lot more effective, to the point sometimes if you have your brake epa to high you'll "endo" the car under heavy brakes.
Down sides, on lower traction surfaces it makes the car very aggressive and snappy, also on low speed sections or off throttle the car wants to rotate easily. But this could be tuned out with some oil changes in the rear diff.

Maintenance wise, if you build them right and use green slime on the seals, they last for a very very long time. The biggest benefit of them is on high traction surfaces, AND no more stripping diff gears. On a low bite track I would still prefer the traditional ball diff, but a lot of tracks out there these days are leaning more toward the higher bite side.

Nice review thanks for the info....

Finally had a chance to run my B44.2 last night and WOW!!! Why doesn't everyone drive one? The acceleration and agility of this buggy is unreal. Even though it took me a few packs to get used to the difference in handling between it and my Losi 22 I am now in love with this car. The rear of the car felt a little loose but that's the way I like it. I could see that adding a little ballast would settle the rear down but then where is the fun? haha I did break a front arm last night but at the same time it didn't break the middle web on it so I was able to finish the pack no problem. I didn't even realize it had broken till I got back to the bench. I also found out how easy it is to replace a front arm, just a few minutes and I was ready to go again. My motor temps topped out at 140 and esc was running about 125, gearing was 18/81. Oh I did have one more problem with clearing one of the triples at the track, I kept overshooting it!!! Haha but that was mostly do to switching back and forth between my cars and my 22 needed a little bit more run up to get the necessary speed to clear it. Can't wait to get more time on the track!!!

As a side note I don't understand why everyone wants gear diffs, I prefer to work on ball diffs than gear diffs. Cleaning out gear diffs was a pain.

Someone told me that the caster diff should drop right in. Can anyone confirm?

If you want to try the gear diff, seriously - buy a Dex410Rv3 and convert it to BB springs. The small bore shocks are not that small and they're quite good.

For $200.00 you can have a whole new car to play with.

I just bought a 44.2 and I like it and my 410v3. I just like trying different cars as it is.

Marcus at RC Shox tried it and it would require machining. Not a drop in.

I know where you could see some videos to help you get started. :D

LOL I may have to some more with all the new stuff. JC has been putting some cool stuff out and the Avid upgrades are very nice. I kinda want to try the Aluminum chassis.

The more i think about them, the less interested I am. I enjoy working on my cars, its kinda like a therapy for me. I'm not a fan of gear diffs at all to be completly honest, but then again, to each his own. I just kinda hate how rc is becoming more of a less involved hobby now. I remember the good old days of building batteries and cutting coms on my motor every few weeks and having to work on my cars or theydont work right. Now, you can have one battery and not worry, never work on a motor and its perfectly fine. Gear diffs to me are just adding to it. Pretty soon, you wont even have to build the cars... oh wait, they are selling them built too...

Sorry, just my little rant here, not aimed at anyone at all.

But in all seriousness, I will never run a gear diff in an associated vehicle.

The ability to put gear diffs in a b44 is the ONLY reason I'm getting one again. In FL we race on high bite clay that will shred even the best shimmed plastic gear in the ball diffs. I loved racing 4whl a few years ago but got sick of stripping diffs. It's why I sold it and frankly one of the reasons the class died in FL. I have the gear diff conversion on order from bugle boy and can't wait to get it installed. Watched Felix Law (a very fast FL racer) blow up 2 stock diffs last weekend at Mills Pond.

I do find it ironic thou to put Durango parts in an AE to make it bullet proof LOL
