Need Advice for Suspension Lift on 2018 Ram 2500 with stock air susp

[jwade520]

I have a 2018 Ram 2500 Limited 4x4 Mega Cab with factory air suspension in the rear. I would like to keep the factory air suspension. I want just enough lift to fit 35 12.50s and have zero rubbing and no trimming. Also maybe improve on the factory air suspension. I'm aware most likely I will need new rims with a specific backspacing and offset. Need advice on that also. Also, I do pull a gooseneck with about a 15 to 18k Lb. Backhoe.

Appreciate any advice I can get. Thanks

Hello J, 35x12.5 should work without needing a lift. I have a "16" 2500 with springs all around. I installed a RC leveling kit up front.
I run Wildpeak M/T 35x12.5 on 18 inch factory rims with just the slightest rub on the front trailing arms at full lock and the front suspension compressing.
