Upgraded X maxx diffs

[ross_jsy]

Hi guys

My X Maxx has just stripped its rear diff and I am only a handful of packs after putting an 1100kv in it. Not really wanting this to be a regular occurrence so wondering if anyone has some tried and tested upgrades for the diffs?

I see Vitavon do a hardened steel ring and pinion set that is rather expensive but if it is bulletproof I'd go or it. Welcome to any other suggestions.

Cheers

I heard the Hot racing diffs are good. You must have landed on throttle pretty good though lol. I have a TP 5670 in my XRT and I've not killed a diff yet.

The aluminum diff covers are a must on the Xmaxx imo, the aluminum diff cups help too but the covers are a must... Hot Racing or Vitavon, doesn't matter.. I wouldn't spend money on "hardened" gears unless you do covers and cups and are still having a problem. And even then, like Moirae said, landing on throttle will do it every time on the big trucks

This is why I am wondering if I am over reacting and just to stick a standard diff in as I see loads with big motors in with no issues.

Zero landings on throttle, it has been jumped a total of I think 3 times before the last ESC mount broke and cut the RX wire, and they weren't anything crazy. Just hard sand and field runs for the remaining couple of packs, no standing back flips, nada. I first noticed what I thought was a click last night whilst braking.

I put the aluminum diff cases from the Xmaxx in the front and rear diffs, I put a shim in front of the output drives, and I put aluminum diff covers. No more issues. Don't forget the drive cup sleeves too. Check out my profile. I have a build threat for my X-Maxx for further detalls

Cheers I'll give the Ali diff cases a go first.

I actually discovered the missing teeth whilst pulling out the diffs to install the diff cups funnily enough. Put it back together and all I could hear was Kevin Talbot's "it's really getting it now" and sent it off properly lol

Another huge thing is the upper and lower bulkhead having a tight fit and no damaged threads. I'm running H.W. 800kv combo, and have went full circle now. I use stock HD gears, shim behind the pinion. Also an aluminum cup with an extra shim behind the side gears. I did not have good luck with the vitavon gears. They never broke, but did wear out fast, like not properly heat treated. I beat on my truck pretty severely, and they were done before 20 packs. It was nice having the punch turned up for a little bit.
