Complete kit of bushings, pivot cups, and washers for optimal adjustment of Evolve, Vestar Blackhawk, Flipsky 12" & 15.2" electric skateboard trucks. This box has been developed after numerous tests, and mixes different shapes and hardnesses of cushions for a perfect balance between maneuverability and stability. The Krank formula, allows you to refine the adjustment by playing on the tightening.
Choice of Hardness:
Extra Soft (84A / 87A): Riders 50Kg and less recommanded. This is the softest setup for this kit and is for our young riders or those who want the most carve possible. The bushing shapes mixed with the Krank formula continue to keep the carve stable and predictable.
Soft: (87A / 90A): Riders around 45Kg and 68Kg.
Medium (90A / 93A): Riders around 68Kg & 91Kg. This setup has a more carve than the 93/96 box while keeping the stable feel that a tighter setup would have.
Hard (93A / 96A): This is typically for 91kg+ riders or for riders who prefer a stiffer setup with more stability and less carve.
Want to carve more? Try using the bonus cone bushing we supplied in the middle of the box in front position 4 (roadside). You can also use the flat washers on the barrels (position 3) if you need more carve. Don't be shy to play around with washer configuration. Make sure you get the kingpin nut snug enough to not loosen and don't tighten down to much (Making the bushing bulge excessively).
