2000 chevy 1500 8 lug swap question

[Russell]

So, I am looking at buying a little short box chevy as a winter driver. That said, I'd like to upgrade the rear axle to an 8 lug 14b SF and swap the front to 8 lug so I can share wheels and tires with my 2500hd.

I know the 9.25" front diff does not fit in the 1500 trucks, but can I put an 8 lug unit bearing on and use the 8.25" diff and half shafts? Will the bigger 3/4 ton brakes fit on the 1/2 ton knuckles?

If not, is there such thing as lift brackets that will allow the bigger diff to be fitted in? I plan to eventually install my 8.1l into this truck, hense the axle upgrades

But it sound like a cool plan!!

Which body style.

If its the order (classic 88- 2000)

There are two options for the back.
A 9.5 14b SF, or a 10.5 14b FF. Should be a bolt in with the exception of driveshaft lengths.

Front I'm not sure about 8 lug outers, but I have put a k3500 front diff in where a half ton diff was and kept it 6 lug.

I think to run 8 lug on the front you will need all control arms, knuckle, and obviously the front bearings.

I've got a full 2500HD parts truck to grab whatever parts I need for the front end, no problems!

This is a 99+ NNBS truck, btw!

Currently has a 4.3L V6 / NV3500 / NP241 combo in it. I'd like to upgrade to either a SF or the 11.5 AAM from the 2500HD in the rear, and get the front 8 lug with about a 6" lift and 35s. Of course, swapping in the 8.1L and an NV4500 / NP241 combo.

Went and looked at the truck this morning and really liked it. That said, the engine needs a new MAF, and either new O2 sensors or new cats. Good up to 1/4 throttle, then falls flat on it's face.

Dude is asking 5700 for it, I offered him 4400. If he'll let it go for 4800, I'll take it. Otherwise I'll let it go and keep watching. Its a really nice and straight little truck, but as bare bones as I've ever seen. Literally has no options at all (no AC, manual windows / locks, manual trans / manual t-case, 4.3L etc). If I buy it, I'll be swapping interiors with the 2500HD to get all the power options installed, as well as swap in the big block with AC etc.

sounds like swaping good body to 3/4 ton frame be faster
