Anyone here happen to have any experience with this diff? I like the idea of being able to engage/disengage with the flip of a switch. TrueTrac looks to be built a little more stout but some have mentioned some drivetrain noise with it. Pulled the rear end today to have the tubes welded and was thinking of upgrading the diff while its out. Was considering some aftermarket axles as well but the stockers are already 31 spline correct? Car is a nice weather only street car/strip so trying to make the rear end strong but driving friendly...
