So far it's been great. I went from a 2011 Z-71 with 3.08 gears to a 2013 4x4 with 3.42 gears. The new rear end gears make a big difference however the Z-71 suspension was much stiffer. When I first hooked up the TT to the new truck it really squatted the rear end much more than it did on the Z-71. Re-adjusted the WDH and now it's fine. I take it easy on the road, 60-65 mph, but still a little nervous as this is my first TT.
