I have a Ford Expedition 2003 model, with coil springs.
I changed OE shocks for Bilsteins for some years ago. Truck handles really well, but it is a little to firm for my liking. I would like a soft handling, almost like riding on a cloud. I am not worried about the truck handling as a sailboat, as I almost never do any high speed driving.
Does anyone have experience to share with soft dampers? I don`t know if there is oildampers for second gen. Expedition, but I wuld thing that would be more comfortable for my type of driving.
I'm not sure you'll notice the difference your looking for by simply changing shocks. I think the spring rate would dictate more what your looking for and as far as I know (maybe some one does?) there aren't any softer after market springs. You can try a softer side wall tire and it will help some. I recently switched from continental lx20 to michelin and there was a very noticeable difference, but it's still pretty rough.
I have thought about spring rates. Ford in the USA wont tell me if there is different spring rates for my year. They keep telling me dealership in Norway should provide me this information. Problem is that there is only a few US trucks in Norway, and dealership cant give me any information.
I have searched for aftermarket springs with lower springrate, but cant find any.
As for tires, I cant change to P tires. Norwegian laws tell me I need LT tires.
I don't know if you will see much difference by switching shocks. I have noticed a significantly better ride by dropping the air pressure in the tires to around 30. Two problems with that is a bit more abnormal tire wear, and the tire pressure warning light will come on in colder temps.
The tires are most of your ride quality issues. The LT tire will be a stiffer ride. When we put 10 plys on the F250, we could notice a significant ride quality difference (rougher) than the 8 plys...

That is just flat out bad and dangerous advice. Running your tires low reduces traction and braking ability because the tires are not flat across where they touch the road. It also decreases MPG, and cause the tires to run hotter. Low tire pressure also causes excessive flexing of the tire and leads to early breakdown and cracking of the rubber material.
