hey guys i am working on my 91 c3500 and doing a flip kit on the rear axle right now. i took out the overloads and doing a set of 2600 bags over the axle to help with the weight. i tow a gooseneck and other bumper pull trailers with this truck. i want to run a Adjustable style shock. i have used 2 different ones in the past on other projectors. i have used the Rancho RS9000XL and just used a set of QA1 Street Star on another truck. i haven't used a set for towing before. my though's were i could switch them for a little nicer ride for when running without a trailer. but then firm them up when loaded. anyone ever run something like this or something similar?
