Your van has got to be inspiring people to snatch these AWD 1500's up!.......
Give those old conversion vans a way to redeem their fate as a tacky relic from the SUV line at the Elementary School to chasing trout on mountain streams. The Van might reward you with many trouble free miles for the effort, with the right driver these AWD Vans are very capable......
I noticed the extra wheel travel soaking up the bumps immediately, instead of the harsh cranked torsion bar feel and no bumpsteer. These vans drive like a stock SUV or PU on any road surface encountered even on windy days.
I had the Hellwig 1 1/8" rear swaybar (not the 1 3/8") on my wishlist and am not sure the need is there, looks like an easy bolt on # 7623....

Some info on your rear shocks, 24-185615's have softer valving at 287-77 vs 389-73 Bilstein spec's to control a 3/4 ton van spring pack and 361-68 for a 1/2 ton van. Bilstein told me they will re-valve your longer 5100's quickly for minimal cost, just shipping? I just wanted to mention that if you find need a little more control back there, he also said they might issue part numbers if the interest was there.........
