I have 2002 chevy with a 5.3 and a 8.5 rear end and im looking for posi trac for sale of a 4x4 swap out carrier

 

try the gm classifieds, on the thread title put WTB (want to buy)

 

go on ebay. although i'd look into a Detroit Tru-Trac or Eaton posi. worth the extra money. the OEM G80 posi sucks. i did a burnout tonight, no brakes, and i then backed up to see my work. well the right wheel left a nice black line...the left one was a faint outline. the left mark also trailed off but the right wheel kept spinning. clearly it didn't get even close to the torque the right wheel got. next mod for me is to get rid of the G80 and get a Tru-Trac.

 

the truetrac is awesome, i got mine along with 4.10's put it monday. When you take a turn everything is smooth until you give it a little more gas and you feel it lock and it barks the tires. As soon as you want it to it goes from an open diff to a locker. I got mine from Summit i believe it was right at $400.00

 

try eaton or yukon i bought a yukon after i placed them side by side and noticed they were identical and the yukon was $50 cheaper and its rebuildable using parts from either manufacturer

 

where would i find a yukon at?
