Question about posi. I have a 03 ECSB 5.3 and damn if the thing isnt pegleg I have tried to look for a conversion kit, but all the web sites that I have gone to just confuse the sh*t out of me. I just want to find a site that would give me the vehicle specific choices to convert my truck into a true asphalt ripping machine HELP

 

Im doing a search for one as well and i believe i am going to get mine from www.speed-eng.com. It is a eaton posi unit for like 399.99.. I may can find it cheaper but that is one of the best prices of seen so far..

 

How do you know if the unit will fit your truck or not???

 

look for 8.5 30 spline 10 bolt

 

yup,

i know a few places you can get it. PM me if you want the names.

 

Also make sure it is for 99-up. They use a different carrier bearing size.
