What is the different between high and low skateboard trucks?

Low skateboard trucks

Low skateboard trucks are meant to be ridden with small skateboard wheels, up to 52mm. They are better suited for tech tricks and grinds and make flip tricks a little easier by moving the center of gravity closer to the board.

High Skateboard Trucks

High skateboard trucks will make deeper turns, and allow you to run bigger wheels without wheel bite. They are good for pools,street cruising and for everyone who likes to run loose trucks.
