Skateboard trucks are usually made of alloy metal and are what hold the wheels to the board. Manufacturers are experimenting with different types of metals to try and improve the endurance of the trucks while decreasing their weight. Trucks are made in assorted degrees of hardnesses, which affect the ease by which the skateboard turns. Skateboard trucks consist of the following parts:
The Baseplate—the foundation of the skateboard truck. This is the portion of the truck that is bolted to the board. Most trucks have the standard pattern with four holes that fit any deck.
TheKingpin—the large bolt that comes through the bottom of the baseplate and secures the axle to the foundation of the truck. This may be adjusted to allow more maneuverability.
Bushings—what gives the skate board truck the pivoting ability, which enables the board to turn. Bushings are available in different hardnesses that will affect their overall performance.
The Hanger—the part that interlocks the axle with the bushings and kingpin.
The Axle—the longest part of the skate truck. Wheels are attached to each end of the axle where a thread is provided for security. This is the part that you grind on. This is also one of the most important parts to take into consideration when choosing which trucks to purchase. In general, the axle should not be longer than the width of the board.
