Just got a 23 2500 with factory air on 20', couple of questions i could not find/understand that answers to doing normal search

[ntino]

I would like to go 285 65 r20 tires on the truck, small 2" lift in front using a spacer(possibly a spring) and bring up the rear a bit by adjusting the sensors for a level truck.
I dont understand if I need upgraded UCAs and if I do what is the part number for the mopar ones? I am only able to find people doing this on 1500 and they are different on 2500 from what I understand?
Does the 2500 need upgraded UCAs?

The 2500 has a live front axle with radius arms. Spacers work fine, but may require a shock extension/replacement. I prefer lift coils, I am running 1" Thuren coils in front on mine... welcome to the forum!

Understood, sorry totally forgot it was a live axle... does anyone know which spacers to get for the rear airbags? (I guess just so I have more extension)?

no reason to lift for that tire, 295/65r20 fits with no lift no problem. If you want to lift Thuren makes a great kit, shocks and springs. If air ride the rear can be adjusted by just changing a lever, If you go to longer shocks in the rear like you can get in the Thuren kit you need to add a spacer so you don’t over extend the air spring. Carli makes a nice 1 inch spacer for the airbag.

I have all of those things on mine, Did not need or want the lift but added supplemental rear air bags to reduce left to right sway, needed the extra inch of lift to have enough suspension travel to the stops built into the bags so I matched the front with the 1inch thor in spring.
