This is really concerning me. After all these days and days spent on trying to get these gear boxes perfect, I may still strip the gears in a few race days?

May I ask how many shims you had and where? When I check for free play between the gears, the mesh seems night and tight. I should mention that I'm using the plastic reinforced ones right off the bat, though.

Wondering if my Dampers will fit on it.

My are just under 59mm from top to bottom, but you could easily build them to be 60mm.

He's referring to a TB04, I think, he doesn't have the EVO.6, and running either 21.5 or 17.5, I'm not sure when he stripped them.

Oh, so you're talking about the miter gears between the spur and the shaft? Ok, yeah, I have the aluminum ones and they feel pretty solid. I thought you meant you stripped the gears inside the transmission cases, that's what I'm somewhat worried about.

Two quick updates:

1. The 74T spur I recommended may be a tad too small for VTA, depending on the FDR you're after. I think a 76T or a 78T may be the sweet spot after all, but ARC has those too. With the 74T and a 50T pinion, the motor is almost maxed out on the closer-to-the-spur side of the motor holes.

2. The kit 44mm DCJ shafts are too long for a gear diff up front. The spool has deeper cups than the gear diff. I have 42mm shafts on order now, I hope those will fit properly.

3. After all this work my car only free-spins for about 6 seconds. Oh well. It's nowhere close to an Awesomatix, but I think it'll be good enough for 25.5 club racing.

yes I was talking about the miter gears...reinforced diff gear is good to have. But stock one is seem to work just fine..

Pretty similar to most of you guys here, I'm using the TB04 Reinforced gear set (#54593) already in the front and rear gear boxes. Those reinforced gears at the spur gear holder and the central shaft seemed working well. Since I am running at medium size track, I do use heavy brakes at some of corners at the track, I find it may be one of the main causes for the stripped gears in the gear boxes. I'm not sure if an aluminium gear box would help to keep the gears well in position and then they won't strip that easy in my case.

About the shims I added in, I did follow the instruction and I didn't find any binding of the drive chain so far.

I have the impression that the quality/durability of the gears that Evo 6 comes with can stand for the loading for 13.5T blinky, perhaps would be the best for 17.5T or even 21.5T but not up to vigorous loading from 13.5Tboost, not to mention modified class too!
