I have Monroe Reflex on the front which absorbe bumps very nicely. The combination of the KYB Monomax on the rear (which work with the sprung weight); we also have the Explorer Express anti-sway bar AND the Roadmaster Active Suspension that fit on top of the leaf springs (which work with the unsprung weight). The ride is incredible. I have come to the conclusion that the RAS is a MUST regardless of of what shocks you put on, or whether you upgrade the anti-sway bar. Just ask anyone that drove our ST at the Kingman, AZ meet. After driving over 1200 miles, round trip, from Sacramento, CA. to Kingman, AZ. I have found the addition of the RAS to be absolutely indespensible on any '01 - '05 ST. :wub:
