I blew my g80 up

[avilleg0]

i have a 1988 c1500 sbc with a g80 3:43 gears with 250,000 miles on it. I did a 5.3 4l60e (stock) swap about 2 years ago and i work on it when ever i have spare money and time. Last week i freshen up the transmission put a stout shift kit in it with some fresh clutches. This morning i went out to run some errands and i got on it from a 20 mile roll and hit 2nd gear. I heard a loud pop sounded like my drive shaft came out turned out something metal tore out of the diff cover.My passenger axle wanted to come out i think i granaded my g80. My question is what should i upgrade to for the future my plans are around 450hp for this truck later on. Thanks

14 bolt no question I'd like to see pics of the 5.3 swap also

14bolt would be nice but you gotta do new axle shafts to be 5bolt lugs

Not nesicarrily there are 5 bolt 14 Bolts or you could convert to 6 lug

These were in mid '90's GM station wagons. Unlike a Gov-bomb, they are rebuildable & can be modded with stiffer springs and clutch packs made of different materials. This carrier fits inside the housing you have now.

And yea, it's all still inside a 10 bolt, (not as beefy as a 14b!) but they will take a bunch more power/abuse than the G80. More predictable in their lock-up characteristics, too.
If you go to this, a complete bearing kit install would be a good idea.

I kno their aren't 5 lug 14bolt axles stock but I meant as is switching for 5lug. Me personally since its a 2wd an my own truck is 2wd its more money for me to convert the front to 6lug. Plus I wanna keep my current wheels.

Hmmm haven't actually thought of the 90s station wagon axles! Were they in everyone or most? Are the axle mounts where they bolt to the leaf springs in the same place?

Actually there are stock 5 lug 14 bolt axles; they were used in the 454SS. Brakes on the 454SS 14 bolt are the small ones though.

As far as converting a 6 lug 14 bolt to 5, I guess you overlooked the pic I posted.

He's not suggesting you use the whole rear end, which btw is coil sprung and on a trailing arm type setup. He's saying you can get the posi carrier from it and use it in your existing housing.

Moser will drill and fill the axle shafts for about 80 bucks, 10 brakes bolt on in place of the 14bsf from the axle flange out. Just get one from a 6 lug C2500 with the u bolt plates and a conversion u joint.
