Sure, there are guys that run this set up... but I
have to ask.... why. To me its a redundancy thing.
Lets break it down, the front segment of the spring
does the same job as the ladder bar... it holds the
axle in place and lifts the body but the spring has
possible rap up where the bars dont. Next is the rear
portion of the leaf spring... this is the part that
allows the body to move up and down.... and hold the
body up. This is the equivalent to the coil on the
shock.... they are equal but the leaf weighs more.
Shocks... they both do the same job but the coil over
shock has a couple of alum parts to hold the spring
Over all.... why run both it would be heavy.... JMO
