    Well here is the issue. For what it will cost you to regear the back axle you could buy a 14 bolt with a Detroit used. If your seroius about going to 35's it might be something to concider. Now that still doesn't fixs the big problem...the front. If you lock the front it's just a matter of time before you blos a shaft. Leave it open it will do ok. Now if you convert to 14 then you also need to figure in the cost to conver the front to 8 lug and new rims.
    That said I still run the half ton gear with 4.10 a Detroit in the rear and a lockright in the front. I'm easy on gear. 35's it will do ok but I would carry a spare rear axle shaft. If you had a 10 bolt I would say scrap it go for the 10 but since you have a 12 they hold up better. Also a 12 with35's will have more ground cleanece then a 14 on 36's heck probably more clearence then 37's.
    Just need to really put some thought to what your going to do with the truck. If your positive your not going to go bigger than 35's...the stock 1/2 ton gear will probably do fine.

    Like Grim said look into the cost of everything. I went 1 ton because I plan to run 38's soon. Not counting cost for tires, it cost me $1700 for axles and wheels. Just to upgrade the stock 10 bolts would have cost that much with parts and labor.

    And 1 other thing, even upgraded the 10 bolts would not have been as strong.

    Really depends the plans for your rig... I have been debating the same questions. Basically if you don't do rocks you can probably get away with more. Tire size, motor power, etc. also come into play. Also if you plan to run a locker then breakage is gonna be more prevalient then open. You can beef up a 1/2 ton with aftermarket axle shafts, either steel caps and arp stupds for the carrier or a reinforcing diff cover to keep the gears from deflecting. Also aftermarket gears are stronger most times then stock GM ones.

    So Grim,

    What you are saying is that 12 Bolt will hold up with 35's and light wheeling???? I have been considering an axle swap. But so uninformed...............
