I have air ride seats in my 3500 reg cab. I bought the unit from my local Peterbuilt dealer. They came from Seats inc. up in WI. The air ride portion is designed for short floor to seat height. I can't find the part number yet, but I know that reciept is here somewhere. The base is designed for a flat floor, like an FL70 medium duty, so the install requires welding a mounting bracket that can be bolted to the floor. Then the air ride unit is bolted to this. I bought seats at the same time. These are just like you had in the 18 wheeler. They don't flip forward so getting behind the seat is a little more difficult. I just slide them forward. The center console is not as good for resting your arm on since you are moving and it's not. The real problem is getting the seat belts to function well. If you did not want a shoulder harness it would be slice of pie. I may take the center console out and build a nice storage and ham radio area in it's place. Then I'm going to want to buy new seat backs with arm rest. Anyway it works and smooths out the jolts. I already had air available from the air ride suspension and exhaust brake. This is to long.
