Good luck! I am intrested in hearing the results.
That sounds simple enough.You shouldn't have any problems with the install, the garage lift will surely speed things up. I installed this about 3-4 months ago. Just jack up the frame and let the suspension droop, and stuff the air bags in the springs. Then route the air lines to your preferred spot.
I spent the majority of my time deciding and routing the air lines. This was the best improvement I have made so far. If you've ever hauled or towed anything that made you disappointed by the ride height when loaded, you can't go wrong for the price of these bags..
