There are two common ways of making skateboard trucks: Die casting and gravity casting.

Both require two moulds with the shape of the preferred truck shape - a lower and an upper mould. The two moulds are placed on top of each other and filed with an Aluminum metal mix which makes the trucks light, hard, and durable.

Gravity casting means that the metal is filled into the mould by letting gravity pull in the mix. In this process the metal is slowly dropping into the mould carefully filling each corner and preventing air bubbles from being created. While the process is very time consuming, the trucks are more durable than commonly die casted trucks. Die casting means that the metal mix is being pressed into the mould under high pressure. Die casting speeds up the manufacturing process and allows the metal to be squeezed into small corners that otherwise could not be reached.

Light trucks are often shaved down to the minimum of metal required. These trucks often come with very precise and thin edges and corners. These trucks can only be made by die casting.

Some very few truck manufacturers world wide, use a special technique of pushing in the gravity casted metal. This enables trucks to be made, with clean edges and small details, while not creating air bubbles. The trucks

In general, an axle width should be chosen that is close to the width of the deck it will be used with.[10] For example, a 7.75 in (19.7 cm) wide deck will usually be fitted with trucks that have axles between 7.5 in (19.1 cm) wide and 8.0 in (20.3 cm) wide. (Standard truck axle nut size is ​5⁄16 - 24 UNF, and the thinner "jam" style with an optional nylon lock.) Trucks that are too wide can make doing tricks difficult and can cause the wheels to get in the way when the skateboard is being ridden. Trucks that are too small reduce stability and can cause wheel bite to occur more easily when turning.
