Does anyone here have experience with the flm savage bulks? Only flm bulks I have used were the hybrid bulks for maxx trucks, and they left a little to be desired...

Hey Linc. I have the FLM hybrid bulks on my flm savage. Lets start with my diff setup

-Flm bulks
-Maximizer 7075 diff cups
-savage xl outdrives, and shafts.

First thing I noticed was the two halves of the cases would not close completely. After further inspection, I measured the stock plastic diff cups and the maximizers and there were no differences. It seems on my hybrids that the bearings were not countersunk far enough, .007" to be exact. My remedy was to machine the outer bearing race .0175" on each side of the bearing. After doing this to both diff cup bearings it fit like a charm. Make sure you give both bearings a thorough cleaning and lube after.

My next obstacle was using the savage xl outdrives. They will not fit through the bulks, so I assembled each side seperately with the bulks, then I noticed I needed a small access hole in the side of the bulk to screw the ring gear to the diff cup. I'm not going to lie, this was a bitch!!!!!!!!!!! After all that work I got them put together. If all there bulks are like this I would not recommend you buy them. Sorry for the hijack! Hope this helps.
