Re: Saggy Springs, can I just...
Just took my van in to the local spring shop this morning and had them add one leaf on the rear spring. The new leaf is a little heavier guage than the others and they had to install new U-bolts also.
Before my interior was done, the van was nearly flat front to rear at about 40 1/2 inches to the bushwhackers. After the conversion, the front had only dropped about 1/4 inch, but the rear dropped 2 inches. Now, $400 later, the front and back are almost the same again. Maybe 1/4 inch higher in the front, but very close. It didn't seem to stiffen the ride that I can notice.
