I did at one point but replaced the front bulkhead and front diff ring/pinion, shimmed and all was good again.

From there I went to v3 diffs and didn’t have a problem with those either so was likely the bulkhead.

Truck is great but no where to really race with it and practice is only so fun. So figured I’d pass it on and got a RC8B3.1 I’m going to give nitro a run again....


You still having issues?

Well I shimmed it with more of them I haven't ran it yet I was just wondering if that was a problem others was having..

With AE every gear box is very different, some guys use 2 shims some need 5+. I know I stripped a ring gear and a pinion in 1 shot. That's when I shimmed for no play but not binding w/ truggy diffs.

AE has updated the diff cases for the RC8T3.1 to help eliminate the issue.

The 3.1 is sounding better and better everyday. I'm gonna try to get another season out of my T3 before upgrading to a 7tr/ 8T? or T3.1

The new diff housings will bolt onto the T3.

So the new diff cases work w/ the v2 diffs? That's good to know

The new bulkheads will accept anything from the V1 through the new HTC diffs. They just improved tolerances and increased the thickness is some spots to keep the diffs from flexing the bulkhead from side to side.

46 pages of reading later to find this bit of info.

Assuming then that the bearing to bearing width is the same between the v1, v2, and v3 diffs, correct?

One more question. Is the v1 & v2 spur gears and ring gears compatible with the newest v3 higher capacity diff bowls or did they change the design?

Thanks guys.

The bearing width is the same, but the ring gears are different for the V3 diffs.

The T3 can very easily be converted to a 3.1. Bulkheads, diffs, CVAs, and HRC arm mounts. I was running the 3.1 buggy diffs last year with the arm mounts and CVAs and the truggy was awesome. I had to run a 12t pinion on the motor but it worked very well.

How are the arms now when I had the version 1 the arms was fragile mire then mugen and cost more to buy are they stronger then they was reason why I ask I am coming from a sworkz s350t

I haven’t broken an arm in a long time. I had a few bad wrecks at Motorama and they were fine.

Happen to know the difference? Hole pattern, or tooth shape (helical vs. straight), or just tooth count?

Just curious. I have no issues buying new ring/pinions, and spur if need be, but I like the fact of the HTC gears and higher fluid capacity.

I believe the tooth count and cut are the same. It has to do with the way the internal face is machined to work with the new diff housing and internal gear. With the new diff cups being larger, I'd guess the hole spacing is a bit different too but I am not for sure that is the case.
