2013 Chevy Express 3500 Passenger Van - Suspension Upgrade

Wth the 3500 van you likely have E rated tires that call for 80 psi max. when you run "empty" or not towing it helps to reduce the psi to 65 or so. Thats what I do on the burb and it even says to do this in the owners manual. the E rated tires are very stiff at max psi and with no load in the vehicle will bounce it arund quite a bit. I would try that before you start spending $$ on suspension upgrades.
