Re: Here is my 1990 Suburban

Re: Here is my 1990 Suburban

Ha - I figured you'd say pizz off! Mine is likely to become my wife's truck soon, but I would if I could.

Instead of guessing what gear you need or relying on the opinion of others, play around with tire/gear/mph or tire/gear/rpm calculators and see what gear suits you. Offhand, 4.88's sounded high. But I ran them through this calculator - http://www.angelfire.com/fl/procrastination/rear.html - and they're not a bad choice at all.

Your transmission ratio (final drive ratio, overdrive ratio) is .70.

Re: Here is my 1990 Suburban

I talked to this guy here locally for awhile yesterday.. turns out he's a pretty big deal.. has quite a few sponsorships and all. He went through the math and to put it back to factory RPM 4.56's would do exactly that, but he suggested 4.88's for a little more umphf. And since I wont really be going over 65mph in it, we decided they'd work perfect.

Re: Here is my 1990 Suburban

I ran 456 gears in my old 84' Blazer with 35" tires... had a shift kit in the transmission... and was able to chirp the tires hitn 2nd gear. I was happy with the 456s'... JMO. BUT it was hard on the driveshaft and yokes...

Maybe the 4.88's would make it easier on them?

Sorry I think wrote typed that in the wrong order... I meant the hard shifting was bad on the ujoints, etc. You should still be fine with the 4.88's as others have said... I was just stating that the 456's gave me plenty of get up and go.. thats all.

Re: Here is my 1990 Suburban

I finally got the gears done. I'm glad I went with the 4.88's! Its a whole new truck now.. OD is back!
Forgot to add, He put in a factory style limited slip, clutch style rear.

I also put a new Sony stereo in.. I'll update the thread with new pics soon.

Re: Here is my 1990 Suburban

Big update - I cleaned her up and might have a buyer. I hate to part, but I got an offer hard to refuse. Here are the pics. She will be missed.









If you're still here and want to see ALL the pics, here go
http://mac-ink.com/forsale/90gmc

If my buyer flakes, it could end up on ebay or here...

Where is the fun in that? Go intimidate a few Priuses, and you will feel a lot better.

Well, the new owner is picking her up today. I'll miss her, but there will be another square body in the future for me.
