I have a 89 chevy 1/2 ton 4x4 with a few mods done to it. not really the serious offroad truck but it does see its use. i have rebuilt the rear end (10 bolt) three times due to poor work from a shop 1 time and twice from mechanical failure. I have killed it again with my stupidity of using it as a tractor. I want a strong bolt in with 4.56 gears and still be able to run my six lug wheels since they are new and fairly expensive. I am running 35 14.50 tires on it and do know that it is not the best for the truck. any help for some good companies to check into will be greatly appreciated.

You will have to machine your own.
1) buy some AISI 4340 steel rod
2) rough machine it to near finish size
3) heat treat it:
....a) heat to 1550F for 1.5 hours
....b) oil quench for 15 minutes
....c) temper it at 1000F for 1.5 hours
4) verify no cracks with magnaglo
5) finish machine/thread it
You cannot get any better. If they break, your overall design is too light-duty.

Why in the hell would you listen to dodgedude tell you about a Chevy, go with a Rockwell750,...or listen to Dodgedude, his info is on the money, 10 bolts are notoriously weak, and a semi floater is still way stronger than what you need. Read a book or two and you can even gear it yourself and save some dough. I thought it was out of my league, until i did my lift and changed to a 4.56 since that I've done a 3.42-3.73 a 3.73-4.10 a 3.73-4.56 a 3.73-5.88 it's fun and it's not as hard as you'd think, just buy the tools and follow the rules. Since it's an '89 it's got 16' wheels right? a 15" wheel conversion is possible, it just requires grinding, or an offset that eats bearings

you can search the junkyards for a semi-floating 14 bolt axle. they do come in 6 lug and not just the 8 lug they are normally. grant it, its not the 14 bolt full floater, but it is a fairly stout axle.
but you will have to have it regeared to 4.56 to match your front. it was available in the 88-97 body style trucks so the spring perches will line up as will the shock mounts, just will have to get a conversion ujoint for the drive shaft.
the 10 bolt axle is not known to be the strongest, so do feel too bad.

order chromoly axles from Yukon, Mossur or another after market axle company, They are strong and guarenteed for life. but still a 10 bolt is a 10 bolt, the weakest of the chevy axles. a ff corp 14 with six lug would be your best bet, pretty bullet proof. might weld up the rear end or get a locker instead of using the weak gm factory locker also.

Whatever it is, make sure it's a grade 8 bolt. Ridiculously strong.
