I was a bit worried they might be too stiff and raise the front too high but given the weight of the heavy 7.3 liter turbocharged diesel engine , My van drives and handles very well. I'm hoping they settle a little more as the ride height is too high and the front wheels are protruding at the top. This is a very minor issue that can go away after a while, and if not, a simple tweak will fix all the issues. The ride is amazing for a 1 ton van. Because these springs have a progressive rate, you'll get the best ride and handling you could hope for. I am very happy with these Moog springs.
