The van is a 2003 with a V10, the stock front springs where too soft and didn’t support the front end weight from day one.
Driving it home from the dealer I realized it was going to need some changes.
I talked to quigly but they where unresponsive and like Grandma used to say
"if you want it done right, you have to do it your self" :Mechanic:
It took about 5 hours to install the springs working in my ice covered driveway. The stock shocks are about 1/2 inch too short at max suspension travel. However the top mounting stud on the shock is long enough to install a spacer to get the length back. I haven’t reinstalled the front sway brace yet. It needs two lowering brackets of about 3 inches, easily fabricated from some 3" channel stock. It doesn’t appear to need the brace in corners and driving around with the heavy duty diesel springs. I do plan a roof rack and more weight on top so I will be putting it back on soon. The front suspension feels much better in the bumpy washboard and no more bottoming out with expensive sounding thumps. The steering wheel needs to be adjusted, easily done buy changing the steering arm a tooth or two. The brake lines are plenty long enough and the axel angle seems nearly unchanged with the Quigley linkage keeping it level.
The rear now remains to be raised about the same 3" or so. I haven’t decided yet if I will do a shackle flip giving it about 4 1/5" and needing a shorter spring block or using an “add a leaf “to the spring pack. Part or the decision is the addition of a winch and bumper to the front end probably lowering it an additional 1" or so.
It drives and handles much better with the stiffer springs. The problem is now I have to keep myself from hitting all the bumps at ramming speed..... :rally_guys:
Hope this all helps.

Jim
