only with Rancho's that come installed as OEM on SuperDuty Ford trucks, and they're a bit harsh, but with some weight rode great, but on the beach in the sand and when you get into wheel hop they almost feel harsher.....I will say too that the KYB Mono-Max is INCREDIBLY harsh (I genuinely regret that purchase on my rwd F150 but I purchased them based on $ as they were half the price of 5100's)

The most important thing is to get the correct valving based upon your vehicle weight and spring rate, otherwise it'll either be too soft, or too harsh.
