A brand of skateboarding trucks manufactured by DLX. Trucks are the part of the skateboard that are attached to the bottom of the skateboard deck, usually with 4 screws. Wheels with bearings are attached to the trucks.

Thunder trucks are popular on the west coast and come in several widths and in low and high configurations, meaning some trucks will allow the board to be closer to the ground, which helps with technical pop tricks and cruising down steep hills in San Francisco.
