I just replaced my air ride with the standard RAM truck suspension supplied by the dealer. Worked just fine not as good but it works all the time!
I up graded rear spring with TUFF Truck progressive springs to handle the weight I carry (1,300lbs) for interstate HWY speeds as it was bottoming out on occasion. Rides really nice loaded or unloaded now!
finally got my Strutmasters on front and rear. Not a as easy as they make it out to be but not too bad. I am impressed with the ride and truck actually sits higher than before. The best thing is it sits level and don't have to worry about all the codes it throws and ever having to mess with the air bags again.
