Not manditory. You will be close to suspension top though so hard may
be harsh ans jerk on bumpy roads when suspension tops out. ALso bear
in mind that you still have a weak rear axle and that if you try to
use springs to fullest, you will overload rear axle assembly. BTW, if
you have used the spring from a 88 thru 99 1500, they would have been
stiffer as well and you could have simply added a leaf to original
spring stack too.
