Though we recommend our Schwenk line of suspension springs for the Vanagon (with its heavy payloads and high center of gravity), we offer these springs as an alternative.  These springs are wound progressively, with the softer upper part of the winding absorbing smaller road bumps for a smoother ride.  While this sounds great in theory, it can work against you in corners as the Van's weight transfers toward the outside of the curve causing body roll away from the turn.  (Our Schwenk springs are wound linearly for an even and predictable weight transfer through corners.)
