You'll need the 43/13 ratio diffs whichever ones you choose, since the 43/10 option drops the ratio too much, resulting in you having to gear up ( spur/ pinion ) alot in order to make any kind of speed.
There are a few good threads to reference for parts / installation instructions:
I have ofna shocks... so I've been looking at Ofna stuff.
The problem is finding the proper ratio. Most of the diff's i'm finding either don't have the gear tooth #'s listed or they are 46+.
These look nice but it might be cheaper/easier to go with UE.
No idea on the gear it comes with or if you can buy others... have to look into that. These actually look nicer than the UE's but I'm not sure which is better.
