If you feel the front suspension is bottoming out on speed bumps, driveway entrances, and pretty much any time the suspension compresses, thats where the RIP kit will help. I believe it lifts the van an inch or 2 in the front and gives you properly valved shocks for a van. My old Quigley van rattled my brain when I hit bumps, but I sold it pretty so I never got the RIP kit.
