I went from stock to Rancho RS5000 which was easy on the wallet, but not a good ride at all. I now have Rancho RS9000X and am very happy with the ride, just soft enough for me, nice and easy rebound and very little bounce. The 9000's were already on my new VX, but the prices are not bad and if you stay away from the in-cab adjuster.... that's $150 less you spend.
