looking for info on what size 14 bolt i have in my 06 2500HD. has the FF axle but anyone know if it's 10.5 or 11.5? reason i ask is i'm attempting to find a clutch type posi for it instead of the stupid Gov lock thats in it. i hate those as they don't always work and it engages really hard. the one thats in my blazer already blew up after 100K miles my new truck is at 76K. suggestions?

Its not "which 14bFF" you have. its whether you have an AAM1050 or an AAM1150. :thumb:

Maybe they use the name to describe something else now, but a Gov-lok is a clutch-based LSD design that sucks.
Fixed

Well if you want to be all anal like PP, It's an AAM1050 which has a 10.5" ring gear.
