Yeah. I had the same problem when my ProComp 2.5 was first installed. It was damned embarassing getting stuck on level ground after one tire would dig a little sand away and the suspension would not flex enough to keep it in contact. . The ProComp is known to be about the stiffest lift available.
1. Remove at least the rear track bar. Removal of the front track bar is more a matter of individual preference. Quick discos on the sway bar are good too.
2. Loosen up the shackle and spring bolts to the point where the nut spins freely when you turn the bolt. I've had mine like this for nearly three years with no problems of them coming loose. If your concerned you can put on loc-tite or gnarl up the threads with pliers.
3. Spray WD-40 or any kinds of lubricants between the leaves to keep them sliding freely against each other.
4. The good news is that the springs do develop more flex over time. Go out and loosen them up with a lot of off road driving.
