Did you unhook the shock for the install? On the Trooper/VX setup the shocks are the limiting factor for axle droop, so it just depends how long your shocks are. Standard shock length, or even the slightly longer OME Nitrocharger Trooper shock length should be fine.

The OME Trooper shocks are 20.35" long, the shocks I am running are 23.1", or 2.75" longer than the OME Trooper shocks.
