Mileage for one. The yard I used only has low miles stuff (my rear springs). But on the other hand, as mentioned above my front springs were very used and they are fine too... Perhaps I just got lucky on those. I know the F-350 they came off had about 140K on it of hard use. the guy was a metal building contractor and his truck had a massive service body bed unit installed with a welder, etc. Plus he hauled a gooseneck trailer with it to all his jobs...
I just came across a set of V/C springs, how much lift would they give without any mods? Is the ride very harsh, arent they rated at 8000lbs? Been searching awhile but not much info on the c code springs.
There should be plenty of info around here about how much lift the V's will give you up front... If you have a diesel, it will be .75" to 1". If you have a V-10, it will be more lift than that.
As for the C's in the rear, I believe they will only lift about the same as the B's. I might be wrong, but I think the C's are similar to the B's except for the overload springs on the C's (which I removed - they don't work on the Excursion). So essentially, IMO, the C's become B's when you remove the overload leaf setup. So expect to get roughly the same amount of lift as B's, which is not much, unless you use the 3.5" tapered F-350 block in conjucntion with the C's (or B's).
Please, anyone correct me if I'm wrong... otherwise, hope that helps!
EDIT: Forgot to add... Mine does ride stiff, mostly due to the leveling kit and the leaves I added to the rear pack. I'd say it rides like a F-450, very solid, a bit harsh for some people. but I like the tight feel and the solidness when I tow. I hate trucks that drive like they're riding on marshmallows!!!
RMBC I am in Commerce-city CO. I get it, I was into jeeps before so the Diesel is a heavier spring which in turn will provide lift for a V10.
And also , the F-series trucks came with taller springs than the excursions did, regardless of engine. The factory Excursion springs are nearly flat when new (and reverse arched when sagging), to keep the ride-height lower for "soccer moms & parking garages" Also presumably to offer a softer SUV type ride quality... Too bad it smacks the bump stops and makes the ride worse that the truck version...
