The AFCO EDGE valve is more than one special valve code. It is an entire package of specifically engineered AFCO racing shocks that work together to provide a performance edge that you will feel the first time you take to the track.
If you want to take the guesswork of out of your shock set-up, the new line of AFCO EDGE Valve shocks is your answer. The unique resistance curve of AFCO EDGE Valve shocks is very different than the resistance curve provided by generic, off the shelf, 3, 4, 5, 6 etc. Type compression and rebound valves. They use deflective disc technology and are user rebuildable. Each AFCO EDGE shock listed is designed to provide specific rebound and compression dampening at both low and high speed shaft velocities to maximize handling for specific track conditions on modifieds equipped with 4 link and/or Watts (Z-Link) suspension only.
