thats cool, im planning on doing the same thing and i would love to see how you did it before i start doing mine

I just purchased two LST2 diffs, aluminum case, for a total of 56.00 (shipping included).
I would like to know which different gear ratios will fit that housing. If anybody has a list out there for me that would be great.

linc, any update on this mod? Thanks.

Following Linc's lead on this, I ordered a couple LST2 diffs on ebay. Total cost was $52 shipped to me in Canada. Here are the updated pics of the rear bulkheads. Sorry for changing this post, the old links would not have worked anymore anyway.

That is alot of material removed... I used a plastic muggy case to do the one I did... I will have to compare the plastic cases to an al case...

I also modded the rear bulk first to fit the LST2 aluminum case. I broke out in some spots, not to worried about the bulkhead breaking yet. I'll be running steel center shafts with Traxxas steel CVD's. I hope they work because I ordered two more for one of my other revo's.

mistercrash I just checked your photos of the lst in the revo bulks, I didn't take that much material out of the side walls on mine, they are thin near the pinion, but the area buy the ring gears is still mostly there. I also ground the rear boss of the lst diffs as much as I dared to reduce the amount of clearance on the rear of the bulk. I will try to get some pics up later.

Well looking at my first attempt after I came back from work tonight, it was now obvious that I screwed it up. I removed way too much material. My only excuse is that I was in a hurry. I redid the whole thing with another set of bulkheads I had and it looks much better. I will post pics tomorrow morning. One thing is for sure about this mod, I hope not to break a bulkhead after :oh: It's a pain to make another set.

I changed the pics in my post #19. They now show the second set of rear bulkheads I did yesterday night. They're much better. I'm now waiting on Traxxas stub axles to use as out drives on either side of the diffs and two 8mm bore Steel Revo drive shaft coupler from RC Monster for the center shafts. I have to rebuild the diffs, one is very notchy and I'm sure it's because it's not shimmed right. Anyone running these diffs can recommend what weight lube to put front and back?

Thanks.

To who ever is interested. I did the front LST2 diff intall. It's done, both front and rear bulkheads are ready to try out on the BL ERevo when it comes in. Only time will tell if the bulkheads hold up after removing so much material from them. I know some of you are using LST diffs already and you had no issues yet so I'm confident it will be ok. Here's a few pics of what I did to the diff cases, the stub axles and the completed front installation.

Looks good MC. I should be doing this soon for my latest erevo build. Since I sold all of mr revo diffs I am stuck with the lst diffs! I have had zero problems running the lst diffs in the lst, which is a larger, heavier truck with bigger wheels/tires.

Thanks and good to know the LST diffs are strong.

I just finished my front bulks last night. I hope to be punishing mine soon. I plan on running a neu 1515 1.5d on 6s (yes thats 59,000 rpm's). Need the rpms since the lst2 has such a slow gear ratio. Might have it running this weekend.

No, you don't need more RPMs, you need to simply gear up. I wouldn't run more than 5S on that motor. Most likely 4S.

Oh come on, dont be scared. Wouldn't you like to know just how good a Neu motor really is? Has anyone heard of a Neu exploding do to RPM's? They are rated to 60,000 its not like a gas motor were high rpm tends to try and pull things apart. I do realize I can gear up, but I really want to see how long it will run on 6s.
