I picked up a 2011 GMC Sierra SLE with the 6.2 376 ci and the 6L80 6 speed automatic trans semi float 14 bolt ear axle with 3:73 gears. This truck is equipped with GM's NHT max tailoring package. This thing is a hoss! It HUALSSSS and then it huals, it is rated for 10,600 lbs I have had 8,800 LBS hooked to it and all it does is WORK! So far I am well please with it.
So far I have tinted the windows, spray on liner, add a gm factory remote start and the tool box for the bead rail system.
