My rear diff is broken and i was thinking about other options other than just fixing it. first i saw the spools but since they dont slip would i be stripping them constatly and would i still beable to take sharp turns? or is thire a better diff like the revo or the tmaxx that i could use or should i just fix mine?

what maxx do you have.

The older emaxx with the 14.4v esc

you can find replacement diffs on ebay for like $12

Spools will damage the shafts very quickly, i snapped a pin on the cvd's within 10minutes in snow.
The spools for the old diffs are quite hard to find, the new ones won't fit.
any maxx diff will fit with a slight easy mod to the shafts, as they are shorter than the old diff.
as above ebay is maybe best option with all the chop shops selling them new.
I got a new revo spec Tmaxx diff bought new diff carrier and I-bar now it's a brushless diff total cost about $15 but prices have gone up slightly since i done it.

I think i might just get the new sealed ones because i hate changing drive shafts they break anough already

yea and with the sealed diffs you can add thick diff lube to make the diff action spool like, but still have some slip.
