Performance Under Pressure - The KranK Formula has quite a bit of adjustability. You can tighten the kingpin nut up to two full turns after snug to 'harden' or 'loosen' the feel of the durometer.
Keep in mind that the rounded edge typically goes towards the hanger of the skateboard truck and should fit snugly into the bushing seat. If there is some slop, you can try flipping the bushing over so that the shaper edge is against the hanger. This will often remove most of the slop for larger bushing seats.
You can combine shapes to customize the feel of your board.
