Default duratrax raze diff question (brushless)

anyone still running any raze's out there? stripped out my front diff not the inner gears but the outer differential ring and pinion or whatever. just so happens that those gears are discontinued, any other diffs that will work in the raze, the guy i got the buggy from said that he put hpi diffs in it but i have no idea. any help? thanks

Dimension wise, it looks like it'll take any bog-standard 1/8 diff.

$25 for a complete Ofna Ultra LX2 diff (same 3.31:1 diff ratio). Should be able to pull it out of the housing and transplant it into yours barring any bearing size issues.

The pulse diff should work, yeah. It's 13/43 (3.31 Ratio) like every other 1/8 buggy/truggy.

Ok I may try to just replace the gears on my diff housing with the gears from the hpi pulse.

The Duratrax 835b diff might work. Its helical cut so I think your would need diff and pinion gear.

Well I picked up a 43t outer gear and a 13t pinion for the diff it was from a hpi savage but the outer gear is to big, it fits the diff housing but will not fit in the bulk head, so on to the next gear. Anyone else have any input?

My 13t savage diff pinion looks like it will work fine, I ordered the outer gear from the hpi pulse so hopefully it will work.

Well I found the discontiued diff gears made for the raze at a hobby shop today while on vacation in florida, looked like it was the only one in a bunch of random duratrax parts! What luck, still have a hpi pulse gear coming to try out as well so ill have a back up gear just in case.
