Definitely  NO!   Provided the length of    the spring under  the normal
weight of the van isn't constrained by the shock (which it shouldn't be)
the length  of the  spring  depends ONLY on  its  material, its geometry
(unloaded) and the weight to  which it is exposed.   Thus, if the  lower
end of  the spring  is  two inches higher  due to  the doughnut and  the
weight is the same, the upper end will be two inches  higher, too.  This
means the van will ride two inches higher.

Sincerely
 Rainer
