Couple thoughts...

  1. Cut your bump stops before you do anything else. Assess the ride harshness from there and see if you've fixed the problem.
  2. Be mindful that there are two types of harshness: (1) slamming/impact from rear axle hitting the bump stops over uneven terrain, and (2) general ride "stiffness" characterized by excessive vibration and the sensation of "feeling the road". Generally speaking problem #1 can be attributed to bump stops that are too close to the rear axle for everyday driving, hence the solution Sue and I and others have implemented. Problem #2 (stiffness) is a characteristic of your suspension system as a whole, so you need to take a holistic approach in fixing the problem. Are your springs too stiff? Are you running oversize wheels and low profile tires? Are your shocks designed for on-road or off-road use? Overall ride harshness is likely a combination of multiple factors, so adding a lift kit (usually nothing more than taller springs and a torsion bar crank on the VX) is not likely to fix your problem. Heck you might even create a new one.
  3. Floating is NOT what you want. It sounds like a good thing when the car is in motion, but generally speaking it can make fast braking, cornering, and steering (especially when you've just hit a bump) extremely unnerving - you feel like you're about to lose control of the truck.


Like I said, start with the stops and go from there.
