Wyatt (awsumdc) of Rock Solid Toys in SoCal installed a Marlin built Lefty in my 07 FJC. The transfer case has the Marlin’s 4.70:1-XD Xtreme Duty Gear Set along with their MASSIVE Heavy Duty 30-spline Chromoly Output Shaft. I went with Marlins uniquely sealed Twin Stick shifter to allow 2 wheel low. The install was done with pride of craftsmanship and the finished job looks and drives great. I need to finish my part of the job my installing a switch in cab for low to allow use of rear locker and A-trac. If I install a switch to engage the ADD first can I then shift the TC to 4 wheel while moving? Would it be the same as locking the hubs on an earlier truck?
