VanDamm,
Here is a post for what I installed and a link to the topic. Worth reading. I think they are better than what was on the van. May not bottom out as much and a little smoother on the road also.

For what it's worth, I ordered new Bilsteins this week for my 2008 Quigley. They should be here Friday and I hope to get them installed Monday or Tuesday. I will try to update, hopefully with a good review. I ordered them from 4 Wheel Parts.
Front 24-186674 $76.99 each
Rear 33-176840 $119.00 each
The rear are actually called struts, so maybe that's why they cost more. Seems like the price varies quite a bit from one online dealer to the other, but they had these in stock and we are getting ready to head out for a month or so and wanted the new shocks.
Quigley verified these numbers for me and had them in stock also, but their price was considerably higher. I am tempted to install them, but my Ford dealer said he would be happy to do it for the labor and they do have nice lifts and all the tools. My knuckles feel better already. I will save the skin for rock climbing on our trip.
