Savage Diffs

[JasonB]

ljoncp, The stock spider gears, cross pins, shims, etc. are a direct drop in. The Vorza cups are actually a hair smaller inside than the stock cups, so you may need to sand a few thousands off the length of the cross pins. Do a test fit first ofcoarse.

This has nothing to do with useing the Vorza cups, but I have recently started to shim my spider gears (both the 2 large ones and 4 small ones with an extra washer). You will have to experiment with this to get the perfect fit. You may be able to fit an extra washer behind all 6 gears, and you may only be able to fit one be hind just the 4 small ones. The idea is to get the mesh as tight as possible without any noticable extra friction. You won't be able to tell for sure if the mesh is right until you have screwed it back together (2 screws should be sufficient for doing the test fit).

I am blown away by how long my diffs are lasting! I run the truck for at least 2 packs almost every day, and although I am a sensable driver I don't baby this truck by any stretch of the imagination. I used to go through diff cups, bearings, and spiders like crazy!
