Tanner by Mittler, with feedback from customers, has designed, developed and extensively tested our new Vision shock. The Vision shock is the most universal, user friendly shock available and hands down yields the fastest lap times. We have extracted the solid features from our Platinum 4 shock such as the NO LEAK seal, quick change spring feature, Titanium Nitride shaft coating, and added several additional PERFORMANCE driven features
