does that kit have a ball bearing in the diff tube? I have one in my RC10, but it's been so long, I have no idea how or where I got it. Otherwise, it this just a tweaked rebuild kit?

thanks for the info, some of this stuff I have no idea about, other stuff, as soon as I see a picture of it, all this stuff flys back into my head and it feels like yesterday!

i never built the one i had (above pic), but i think there was a bearing that camw with it. how it was used...... i don't know.

the one you have is probably the team losi/rps diff tube.

The Jammin' setup diff tube was machined for D rings, but didn't have the bearing in the center like the RPS/Losi unit. It's hard to tell from the picture, but I think the J-418 big diff tube carrier bearing was non-flanged. There was a different type of thrust bearing, like used on the early Stealth 'boxes, too.

yeah, that ad completely helps, now I remember, I've seen that add probably dozens of times.

the jammin kit used the bearing to support the spur gear, where the stock one used the diff tube as a bushing.

the main benefits of the jammin jay parts are the d-ring drives, the extra thrust bearing on the tension spring, and the bearing supported spur.

Hey scr8p- that picture looks familiar.....

I planned on installing it for the next VONats. I picked up a Rad2 that I may run in the "box stock" class if that happens, or I could run it in buggy just to be different.

If I ever get a chance to install it, I'll post up some pictures and commentary.

I just picked up one of these rebuild kits for my 6 gear. It didn't include the diff hubs, only the thrust bearings and washers (part # J-109). I used the stock shaft, drive hubs and rings. So far, so good. Thanks to templeofspeed for posting the pic. It really helped with the rebuild, since there were no instructions.
