They are very nice, my savage is all flm. The only complaint, and I found this out this weekend, is you have to use the outdrives flm sends with them. I broke one of the outdrives on mine and can't seem to find them online anywhere. They are smaller outer diameter to fit through the holes in the bulks. So what I had to do is use one of the stock SHD outdrives and assemble the diff in the bulk, I'm good as long as the ring gear side outdrive dosent break.
Do you really bash your truck or just racing and speed runs?
If you decide on FLM, shoot me a PM before you buy...Got a used set that I'd part with. Did a little modification on them to fit the Savage sway bar kit, but other than that they are clean.
