New burb owner

So my aunt gifted me my deceased uncles suburban. It is a 1975 Scottsdale 4x4. I have lots of questions as it has lots of issues! It has a transfer case shifter that has hi,hi loc, Lo, lo loc, and n....what is it? No 2wheel drive? Where do I find engine codes to figure out motor that is in it? Thee will be more as time passes.nthanks for any help in advance.

NP203 Transfer Case

Look in the glove box for a card stuck to the inside.

Re: New burb owner

Thank you Buffy. I looked in the glove box, but it didn't say for the transfer case. Is the NP203 any good? My aunt told me it was the 3rd motor to go in it.

Re: New burb owner

The NP203 is ok. It's more than strong enough for regular use and occasional abuse but it doesn't get any love because it's a full-time 4wd xfer case and it's heavy. The full-time 4x4 part can be fixed by installing manual hubs if your uncle didn't already do so.

What's the best lift kit that includes springs not blocks? What size tires are y'all running out under what lifts?

That's good that it already has locking hubs. It did not come with them from the factory. Run them free on the street and locked in the dirt. The 203 transfer case acts kind of like a differential and lets the front and rear tires run at different speeds during turns in Lo and Hi with no hubs or locked hubs. It's referred to as full-time 4wd. It works really well on snowy roads, especially if there's a bit of melt here and there. In Lo-Loc and Hi-Loc the transfer case delivers the same amount of power both front and rear like a traditional 4X4. Running the transfer case in Loc with the hubs locked on hard surfaces will bind the driveline and can break parts, so don't do it.

For the best riding "off the shelf" springs, Tuff Country works well. But for the absolute best performing, best riding springs that flex like crazy offroad (that's a good thing) go with custom leaves. Alcan and Deaver come to mind. I don't like big lifts, so I went with 4" lift springs and 35" tires with a little trimming on the rear lower edge of the front fenderwell. There was still just a bit of rubbing when fully flexed out offroad, but adjustable bump stops fixed that.
