Replacing Tech Deck Bushings For Softer Ones This is a simple procedure and can be done quickly. It can save you a great deal of money, due to the fact that it is a great shock absorber for big drops off of large gaps, and allows tech grinds such as k-grinds and salad grinds. 1) Loosten the nut on the king pin of both trucks 2) Take both bushings off of the fingerboard 3) Cut an elastic band into tiny squares. You will need about 8 of them, depending on the thickness of the elastic. 4) Poke tiny holes into the center of the elastic squares 5) Place the elastics on the kingpin, positioning two underneath the hanger and two above it on each truck. 6) Replace the nut onto the kingpin |
