New for this season we will be using a different material in the a arm department. Docol R8 is something that has been around for several years but is used mostly in the racing Industry. Some of the benefits include 10 to 15% stronger, safe non-brittle break mode meaning it does not tend to crack when bent like 4130 does. Docol was engineered to provide a stronger more consistent alternative to 4130 tube. For our new 35.125"-36.5" Viper- proclimb a arm kit we will have new mounting hardware for the arm to spindle attachment. So instead of the several parts and pieces we have used in the past it is now a one piece stud constructed of titanium. These will come standard with every kit. Hope everyone's having a great summer, winter is just around the corner when you think about it. Thanks!
