There were plenty of Z71 and even 4x4 non Z71 1500 trucks with 4.10s. I even seen them in Suburbans and Tahoes.

Awesome. Now i know.

Ok guys. 8.5 r 8.6 most people are telling me they are the same. Some say I need 8.6 can someone shed some light on this. 30 spline correct?

I'm surprised the g80 lasted this long. I put 150,300 HARD miles on it. Never pulled diff cover until it started making noise and acting up. I can get a replacement g80 ready to go with a warranty for 279.00. Or I can spend a few extra hundred and get one I dont have to worry about breaking. Decisions decisions........

It took about the same mileage for my G80..only mine blew up and left me stranded. Don't replace junk with junk, TruTrac and 4:10's are the way to go. I love mine!

@Bryant. What rpm are you seeing at like 65

Instead of pulling the front shaft, you could just unplug the front diff actuator.

2k iirc with a 255/45/20. if thats wrong ill update

go with the tru trac. I made the mistake of replacing a open diff with a g80. Now I have to worry about it. This is of course if you plan on increasing power more.
