Taking the time to properly shim your diffs will make them last a lot longer and costs little except the cost of the shims and your time. Aluminum cases may help but you still need to shim them if you want them to last.

That was going to be my line. You can buy all the best aluminum parts, but if the gears are not shimmed properly they will still eat each other in a very short time. Everyone looks to save a few bucks trying to go with the cheapest parts they can find. If you truly want bulletproof diffs as you first said in the thread opener, then get a good setup the first time and shim the gears properly. You will have more time playing instead of rebuilding, rebuilding, & oh yea rebuilding. Personally I would go for the FLM hybrid diff cases, and put the Hot Boddy hardened gears inside, with an FLM aluminum cup. I believe that Mike sells all of this here in RCM.
