Rebuild transmission for a 2wd slash

[dwtowmater]

I'm trying to build a transmission for my 2wd slash because, I've destroyed 3 stock transmissions. my issue is now that I'm trying to get a diff locker and that is aluminum. I've gotten an aluminum idler gear but, I can't find a aluminum top drive gear. Do y'all know where or what to get.

Something like this? This is from the newer 272R which is the heavy duty version, should be a direct drop in to the old style transmission case

Found this aluminum top gear, ideally meant for drag though

3 transmissions. i've been there. Going on my 5th replacement of my slipper clutch shaft. what @DavidB1126 linked should ideally work. For diff locker, You could do this, or go all out and get this.

instead of rebuilding mine I just bought a 272r was more effort than it was to rebuild lol

i have that gear (and there idler gear) in a gearbox I'm building for a "rustler". so far the only thing i can confirm is that it fits and seems very well made.

I'm doing the exact same thing. I just started the process though...Please let me know what you have purchased thus far...? Anything you think you would have done differently...?

Please, help me understand your wanting of aluminum gears for your tranny when steel is available. The most "bulletproof" 2wd tranny I ever had was composed of steel for the top shaft, idler, and diff gears.

Whats better...? Steel if its better.

speaking of gears, mine are grinding right now. you don't need steel or aluminum gears. if the material is good and the tolerances/mesh are good, plastic is fine. and quieter. and better for performance sense it's less rotating mass and less weight hanging off the backend.
that's why a 30 year old Team Associated Stealth tranny can handle brushless/lipo but a 20 year old traxxas tranny can't handle a 15 turn brushed motor with a 6 cell nicd pack.

I don't know...but I'm asking my local rc contacts and I'll let you know what I find...
