For coils and shocks we chose a set of 10-inch Sway-A-Way race runner shocks with Eibach springs. Two of the main factors to look at when dialing in your coils is the vehicle weight and the type of wheeling that you intend to do. We went a little heavy with our rate, running a 300/350 with the addition of a tender coil. Due to the mounting position of the shock we were limited to around 4 inches of uptravel. Normally you want as even a balance as possible (i.e., 5 inches of up and 5 inches of down for a 10-inch travel shock).
