I run the 2.5" OME with the extra leaf and the HD shocks at all four corners. I have close to 150 lbs on the front (big winch and bumper). I run a 3x5 roof rack and have a 22 gal aux tank. When loaded, I have no complaints about the ride. When the rear tank is close to empty the ride is a little stiff in the rear. However it is still a much nicer ride than the factory setup.
