This kit is designed for Evolve electric skateboards that use dual kingpin trucks.
For simplicity, we will refer to the bushing positions from Board-Side to Road-Side. So for the front, Front 1 is the bushing closest to the board while Front 4 is the bushing closest to the road. The Primary turning pair of bushings are Front 3-4 and Back 3-4 (Board-Side Pair) bushings while the Secondary turning pair of bushings are Front 1-2 and Back 1-2 (Road-Side).
RipTide found the key to settling down your trucks is to keep the pair of Secondary bushings stiffer than the Primary bushings. When adjusting compression, start with the Secondary bushings first. The primary pair should initiate the turn, then the secondary pair should come into play when needed or wanted. This box setup provides agility and stability for your board.
Pivot Cups Fit perfectly in these trucks and help provide a smoother and quieter truck.
