07 suburban lift/level

[Customsound]

I have an ltz suburban I am putting 275/60/20 hankooks on and was looking for a lift or leveling kit for these tires . The truck has air ride suspension and I heard you're the man to talk to . I do pull a trailer on the weekends so it still has to be functional

what does the truck measure from ground to fenderlip in front and rear?

35 3/4 " and 36 1/2 in the rear
