[Rivermaxx]

Pretty much all 1/8 scale diffs are a lower gear ratio. I dont know of any that are the same as stock t-maxx. You need to gear higher if you want to retain the same speeds. Example bigger pinnion or smaller spur. What the big deal about changing those gears Its not the expensive or hard especially compared to buying and setting up a set of 1/8 scale hybrids. I am sure flm website can tell you all the differnt diffs that work with there hybrids.
