Re: How Much Sag F450?
Mine has snow plow springs which bring the front up to 6500 lbs. (7000lbs. axle). The front axle is about 6.5 inches wider. The rear springs were standard with overloads rated at 9500lbs with the 11,000 axle for the rear (Dana 110). Mine has the 4.30 LS axle.
One has to think that Ford designed the truck for fifth wheel users. It does not have the 8 leaf spring pack as the F450 commercial cab-chassis. It has a pack of three, a base and to long thick ones for a good ride when a trailer is unhooked. The truck camper market is so small that Ford could care less about our needs. The result is that the rear spring pack may need some help so that under a heavy camper so it does not squat like a puppy.
I started out with a set of Super Springs on the rear, one spring over the top of the overload. With the camper loaded it sat just about right. We took a trip in the western mountains of Colorado that included a couple of rough Forest Service roads. I opened my widow as we negotiated rocks and holes, and was startled by the noises coming from the Super Springs. When we got home I decided to change the set up. I took the truck to Denver Spring and they put two more leaves in the stack. The setup seems perfect now without the weird noises. I don’t know what the unloaded ride will be.
My camper plus all the stuff I carry weighs 4500 lbs. Empty with a full load of fuel the truck weighed 9100 lbs.
