This is the most useful thing I've read in this forum in a long time, thank you! I have a Caldera (1/10th) and a Shredder (1/6th) and I had assumed all the diff parts were identical. But after reading your post I went and looked them up. The diff housing and outdrive numbers are the same... but the diff-with-case, diff-only, and gears-only part numbers are different on the Shredder (and Earthquake) than the Caldera.

I had kept all my diff parts in one bag and have been using them for both models, now I have to go back and see if I used the wrong ones. For other peoples benefit

Caldera: Just Gears: BS903-105
Caldera: Diff Only: BS903-104
Caldera: Diff-with-Case: BS903-020

Earthquake/Shredder: Just Gears: BS803-027
Earthquake/Shredder: Diff Only: BS803-026
Earthquake/Shredder: Diff-with-Case: BS803-025

Dads: Can you see/feel a difference in the metal gears? My Caldera had a front-center-outdrive bearing failure that ended up eating the ring gear teeth, and I also just replaced the rear diff internals when I had the diff off the truck to replace a hingepin brace (diff worked, but inside the ring gear teeth were 50% gone and sharpening to a point). I also replaced both front-side and front-center outdrives on my Shredder because they were worn... but didn't notice the diff looking any different.

Thanks for clearing up the part number differences for others that may read this post. I should have been more specific and not just said "8e line". I did order the Earthquake complete diff assembly with included hardened gears. For those that don't know, the diff case itself does wear after time and will help speed up the crunching of your diff gears. So I figured since my sons Caldera 10e was about two years old it was probably time for a complete swap out. There is a noticible difference in the hardened gears compared to the stock set. They definately look more machined or of a heavier grade metal. Sadly, they did ship almost completely dry. Not that big a deal but you think they would have at least put a little grease on them for those that don't know you need to grease and check the shims before you install them.
