Gpm hardened gears

[Rcproponent]

Ok, I know this has been slightly touched on elsewhere but I couldn’t find the thread... who here has used thewe GPM gears ?

Are they any better than stock?

I know gpm is rather questionable when it comes to most of their products and I think there is a a couple good ones amongst them...

I’m gonna have some considerable power once the 1717 goes in my rig, just trying to at least prolong the life of these diffs

Any insight appreciated. Thank you.

They strip just as fast on my x-maxx Garbage

All GPM products are pretty weak.

Your best bet would be looking into Mugen parts if a combination of parts will fit. (I have no idea)

I stripped the rear one I got from you just doing light accelerations on flat pavement lol. I really wish stronger diffs existed for them. The only other option is to start shimming.

Sorry about that...

I know full well people knock GPM. They're cheap Chinese alloy and my guess is the steel is mediocre. But I've not had a single GPM part fail on my Arrma so far (check my build log - lots of GPM parts). No bends or breaks... but I don't go stratospheric or run on concrete. and I've been running the diff set in my Noto's rear diff for months now:

Recently disassembled it to (ironically) fit the GPM diff cup, only because I felt the oil was getting low as the stock cup was leaking a little. The GPM diff set I used held up perfectly with the only breakages being the diff pins breaking (standard!) However it was the first time I've broken pins and not split the larger planetary gear as a result! They are not hollowed out like the thin stock ones and definitely hold up to more abuse. So I could actually recommend the diff set, but you may have to an extra gasket with the stock plastic cup after you shim them with Mugen shims as my guess is they could be a little bit bigger than stock. They fit perfect in the GPM cup though

I've not tried the input pinion and ring/crown gear yet but I was thinking about it after the stock ones give in. Nobody seems to recommend them, but as I said, none of my GPM parts have failed ?‍ I can't find Mugen parts in the UK but maybe I haven't looked hard enough, and the GPMs are cheaper and arrived within 2 weeks

Your call ?

Not your fault, I just can’t keep my diffs from stripping. I bought shims for it. Are you still on stock diffs?
