Diff questions

[Serum]

@rhylsader;

the problem with the kyosho cups or the HB C8019 is that you need to use the unneeded expensive blocks from nitromods. (which wasn't his idea in the first place btw, he simple stole it and hit the market with it) the aluminum HPI cup covers this problem in an even better way. I use shims inside the diffs a thin layer of springsteel sheet. (which probably isn't needed with the 'new' HPI diffs)

And i don't use the paper gasket either, i use blue loctite. It seals it up very good, and it tightens up even better.

The GPM housings are available on ebay. The bulkless of FLM is a tad too heavy for my likings. I want to put mine on a diet once i've got my things up and running.

Ok, so the Gpm are lighter than the flm. I really like the flm quality, are the gpm parts comparable? I will most likely buy the flm parts for my flm tanny forward build, and keep the stock plastic bulks for the basher. I know that the heavier truck will be much harder on diffs.

One the subject of ring and pinion sets, are the savage ss metal cased diffs good enough, or should I upgrade them too? Is there an upgraded ring and pinion available, or will a std buggy diff gear set (ofna, etc) fit? The ofna diffs use the 6x16 bearings, so that would be a way to upgrade?

I will try the flm 7075 cups in the basher and see how they do with the stock plastic bulks. I do have a set of the hardened hb internals, will they fit?

i wouldn't use the aluminum cups of flm, since they don't use the large square blocks like the HPI cups now do.

The flm bulkless is more suited for a basher, since they are bullet proof.

a buggy diff won't fit into a savage housing (nicely) because the ringgear is larger of the savage. and to compensate the length, the pinion gear needs to stick out relative far, which causes stress on the bearing, and the other end wont line up with the cup nicely.. (the shaft on the pinions gear is simple too short)

yes, the HB hardened gears will fit. stay away from the kyosho internals, since they are made from cheap/poor quality metal. (the silver/aluminum types)

[lincpimp]

Well, I already have the flm cups, so I will put the hardened gears in them and put them in the basher.

I will put the flm bulks on the flm chassis, just casue it will look cool and be sturdy. I will put the stock ss diffs in the flm bulks, as those should be the best diffs to use.
