Gullwing Sidewinder II

One of the best and most common trucks used for getting some almost absurdly tight turns. A rather unconventional design; one of the only trucks ever to implement a double axle kingpin system, but don't let the abstractness of it all fool you. These trucks are 100% function and efficiency for turning. They can tighten up when you need to; but can push that extra turning radius in a serious pinch, all while still holding the same sort of stability you'd expect from a traditional skateboard/longboard truck.

Double axle/kingpin longboard trucks, 10 inches wide.
