Accessing E-Revo diffs - is it really that hard? - Page 2 - RC-Monster Forums

Whats the best diff cup and outer diff housing available that doesnt bind.I made the mistake buying RD Logics cups and housings and the housings bind and the bearings dont fit the case.I tried shimming,stock diff cups evrything I could think of and they still bind when you tighten the outer case.

Mikes Hybrid's...

Thanks are they compatible with the Slayer center drive shafts.Can I just buy the cases?Will they work with the stock Revo/Slayer diff cups?

The hybrid diffs use 1/8 scale internals. They are pricey, but will most likely outlast the truck. They are the strongest option for the revo so far.

Well I finaly got the funds to upgrade my Slayer diffs.I went with the Integy hardened gears and RC-logics cups and Integy outer cases.The outer cases came with shims.Everything fit together very well with no bindingin the diff themselves allthough.I had to shave a bit of the Traxxas plastic drive shaft on 1 side of the truck so it wouldnt bind on the Integy case.Besides that the diffs are very smooth.For about 100 bucks so far its worth it.The ring gear is spiral cut and very presise along with the pinion.

The Traxxas stock diff both were originaly assembled either too tight or too loose 1 of the ring gears had a screw coming loose from the cup.VERY POOR ASSEMBLY QC.

Well I thought I'd revive this cause I just tore out my front diff, cleaned out all the grease, washed, dryed, filled with silicone, and reinstalled it. It took me exactly 10 minutes to get the diff out, apart, and soaking. I spent 35 minutes cleaning and re-assembling, which is gonna happen no matter what diff your talking about. It then took me about 15 minutes to get it all back together, funny that it's harder to get back together, getting the center shaft lined back up is a PITA for the front cause it's so damn small.

The revo diffs are not that hard to get to but no where near as easy as a lst. Th elst was the easiest to get too. My savage was the hardest and before the X the savage had tons of diff issues. Thats why I sold mine!!!

Has anyone see or used the rrp diff pinion and ring gears? I was looking at getting those and an aluminum diff cup when my diffs go! Any insite would be welcomed

i just built a couple diff's using the RRP ring & pinion along with Emaxx spyder gear's and RD logic's inner/outer case's but have'nt had a chance to run them as of yet, i did have to shim them up to get them nice and smooth

My understanding is that its not so much the gears themselves as it is the cup and the diff housing. My stock gears have held up great since I replaced the cups and housing.

What is your take on accessing the diff's in the Savage X design (and also referring to the new brushless one)? I ask because I have one on order, but I'm second guessing myself on it - those 8ight-T's are looking awful nice, especially since the price on the 1.0's have dropped so much.

Let me know how they do! How did they look compaired to the stock gears? Are they smooth?

IMO i don't think i'll be having any issues with my diff's

the stock gear's are slightly darker and shiny in appearance where as the RRP are more of a dull, matte finish

like butter!

like to hear that. I might have to pick up a few sets

I will be ordering a savage flux. The new design of the x is much easier to work on everything! Also the diffs are better( and better than the ones for the e-revo) The only issue I have seen with the savageX diffs is that they dont come shimmed and they need to be! Once thats done they are golden! The new diff cup for the savage diffs is nice too!

I know the flux will still handle like a savage but it has a more durable drivetrain than the e-revo.

Well that is a classic truggy vs monster truck choice. I prefer monster trucks over truggies... But I am a basher and cannot appreciate the benefits of a truggy

X diffs are definately easier to get to. Shimming the diff is a must with a savage. Does the flux come with the al cups with the steel inserts? Those are mandatory in my opinion, I have tried all of the options for my savage and they seem to work the best. Plastic cups are just junk.

I have had great success with the erevo drivetrain, but you are most likely correct that the flux will be stronger. Now if only Losi would come out with an electric lst... That would put the erevo and flux to shame (as long as it had the mmm and motor in it)

I'm in the same boat Linc. The tracks around me are just to damn far away to get to, and even then I'm not certain that I would enjoy it as much as bashing. I've already got that Hellfire truggy that I still need to finish anyway, so my "sensible" side tells me to stick with it instead of getting the Losi. But then, a clean looking LST2 showed up on Craigslist today, for a decent price (275). I think I will leave my FLUX order alone - it will be my first ever brand new RC. Kinda looking forward to that.

From what I could tell by looking at the spec sheets, they dont say how the diffs are constructed, but I'm assuming its the same as whatever the X has. Guess some of those questions will have to wait for delivery.
