Let me get this straight. your gonna lift your truck. then buy a different type of trailer to accomodate the lift? doesnt seem right. Im guessing you dont own a trailer and def dont know what you getting into with a lifted truck. you are aware it wont handle the weight any more with rear lifted springs and will need to be regeared and reprogramed. (if its diesel the new engine are designed to run at a certain rpm under load. aftertreatment issue could pop up).Talk to a real custom truck shop. not a retail outlet before going this route. take the lift,tire and wheel price and triple it if you want it right and tow worthy. im into my setup 6k parts only and i feel im 1/2 there. Dodge ram with thuren radius arms, king shocks,custom springs and airbags. all for 37 on 20". need to regear or underdrive, and upgrade to freespin front hubs for better bearing spread. tows fine though we run 75-85 in nv. the 20 wheel help side wall issues mentioned earlier
