4200s shread gears

[SixShooter]

Well My son shreaded some gears tonight in is basicaly stock Emaxx. It took two runs on the 4200 to convert the Emaxx into a 2WD moster truck lol So I replaced them with CVDs. Now I guess I have to upgrade my gears. Anyhow, I was wondering if the stock T/Emaxx gears including spiders was hardend? If not, has anyone tried hardening their own gears instead of buying aftermarket gears?

I think the majority of the problem with stock diffs is really the plastic cup and the fact they only run two spider gears. Under extreme force, the cup elongates causing the gears to skip, which ruins them. If you don't want to spend lots of $$$ for the good stuff, I'd at least get an aluminum diff cup and just use stock gears. They hold up ok under decent power as long as the mesh is kept consistent.

Ya, I figure that is my case. Since I'm going brushless, I ordered some aluminum diffs for my self but now I think I'm going to order a set for my son's truck as well.

Either that or get a weaker system. :)

But what fun would that be :dft012:

I tell ya though, batteries has come a long ways. Now days you have to beef up your stock truck to handle new packs. That is why I went to CVDs...I was twisting shafts with GP 3300s.

I put 4200's on my stock Maxx and shattered the idler gears and stripped 1st gear out. Then twisted 2 sets of stock axles in half.

Now I've gone to aluminum tranny gears and 3.3 drive line with spools on my E-Maxx. :027:

Welcome aboard.

Now if you're rock crawling it's cool but Spools are hard on parts other wise.

I'm new to this whole thing but that is what I'm going for. I don't care a whole lot about top speed.

I just like running over stuff. :017:
