If you are looking for the hot set-up for your Dirt Late Model, you need the Afco Edge. These are basically the 1300T series of racing shock but with very unique and specific valving for changing track conditions. They use the same technology as the Afco M2 and T2 shocks but in a user rebuildable aluminum twin tube. You can jump right in with the Edge ten shock complete package, which covers all track conditions or the Edge five shock slick track package. Either way, you will instantly see a difference in performance over any other set-up.
