Description
One of the most important shock characteristics not widely discussed is Hysteresis, which is the delay a shock sees when changing direction or reaches high shaft velocities. Typically a shock that does not change direction well will reduce grip. Reduced grip is simply slower lap times. The same holds true for a shock with high shaft velocities. At high shaft speeds the internal flow capabilities can cause a hydraulic lock as well. A Quarter Midget will see shaft speeds double of what you will see on a typical NASCAR race car or even a Sprint car and the Vision shock has addressed this SUCCESSFULLY.
This piston design includes angular porting and internal channeling always drawing fluid from the wall of the shock where the fluid temperature is coolest. This unique design provides flow characteristics that will allow for a linear, digressive or progressive valving curve.
Tanner by MB, 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 such as:
• Micro Tower shim support Shims will not deflect during direction change
• 62% increased air/gas chamber virtually eliminating rod/shaft pressure
• PERIMETER FLOW pistons reduce hysteresis
• New Sandvick Steel shim stacks
• Lightest shock on the market
• One shock length fits all cars
