yota axles have a SLEW of aftermarket stuff. Upgraded axles, super birfields, as in can handle 38-40 tires out west in the rocks easily, and V8 power also.
5.29 is as low as you want to go ratio wise. Their are 5.71 gears avaliable, but as menationed before, very small and weak pinion.
I'm going with a set of D44's from a scout. Price was right on em! $150 andf they just need hubs and brakes (and gears!) cept I'm going coils all around a a 1 link set up
