First of all, congrats on the truck! I have a 21 limited myself. As you sort through the forum you will see the most popular solution to level the air suspension is the revel links. The revel links alone will cause a much stiffer ride so many add in the daystar spacers bringing the ride back to stock. Then there comes the concern of UCA stress..is this a legitimate concern? I don't know but I would rather do it right the first time on a $75k truck.
Due to the limited data, I went with the Revel Performance Advanced Lift Kit. It is seemingly their new solution to all of the previous concerns with respect to UCA stress and stiff ride. This kit includes new UCAs to accommodate any added stress, daystar spacers, and of course the links. After level install I am going to throw on some 285/55/22 Toyo AT3s. Contemplated going with a 20 inch fuel rebel wheel but I love the ceramic coated night edition stock wheels.
These easy-to-install kits quickly replace the stock sensor arms to Billet Aluminum Fully Adjustable Sensor Links. With these links you can safely level the truck
