I have a 2004 1500. Its got an open diff out back and i want some double wheel action in its place. I remember going to the chevy dealership last year and talking to a sales rep. He was explaining to me that 2006 and up trucks came with 100 rpm locking diffs. Is this true or was the guy blowing smoke up my a**? If so I bet i could get a newer rear out of a yard alot cheaper than buying one of them truetracs. Someone HELP!
don't buy a factory G80. They are known to explode.
Buy a aftermarket posi unit - eaton posi, auburn, tru trac.

The best advice I have ever heard:... Only take B( . Y . )ST advice from someone that is CURRENTLY running a turbo setup close to, or bigger than what you want......
The stock gove-lock won't engage when the rear wheel speed varies more than 100 RPM side to side regardless of year model 99+. They're made for mud and snow traction, not for dragstrip launches.
G80 = Gov bomb = terrorist truck act waiting to happenI kill you
thanks for the direction. i was thinking a tru trac...
tru trac FTW!!!
14 bolt g80 aren't as bad. its just the 10 bolt ones just waiting to explode.
I got me a tru trac off ebay for 350 with shipping. I have a G80 that i was going to put in but after my buddy done a good burnout with his i changed my mind quickly cuz its f*(&^d!! Haven't got my true trac installed yet cuz i aint had the time and i just ordered some 4.10s so when they get here i'll install it all. but yeah don't get a G80
