The rear is an Eaton G80.. I have read about the possible mods to have the Eaton lock for speeds above 20mph ..
but I am still looking at ARB Airlocks for front and maybe rear ..
Anybody else have lockers on their 2006 or 2007 Duallys ..
what diffs does it have ? GM 10Bolt or Dana ? Axle Diameter ? Spline count ?
thanks

11.5 amm. iirc......

Yup... 11.5 AAM... same crappy gov lock diff w/G80

11.5 AAM ist that the designation of the diff ?
front and back ? do you use any real lockers ?
thanks for answering
