We removed the old Rancho shocks that were supplied by Calvert Racing for there monoleafs. The Ranchos are a good shock for the money, but when you have the $$ for real shocks, AFCOs are the way to go. As far as the front shocks are concerned, we happen to be running a single adjustable QA1 Stocker "R". We were told that the front shock for our application wasnt as critical as the rear and that our current front shock would most likely be adequate, so that is what will be on there for a while until they wear out. At that point we will spring for the AFCO single adjustable front shocks. Call Eric for $$ on your particular shock needs.
