The Hydroponic South Park is a well-performing truck meant for skateboards. If agility and best performance on ramps, pools or bowls is what you are searching, then search no more - this high truck is here to give you just that. The truck fits most skateboard wheels on the market. But usually, you would aim for wheels with a diameter of around 56 to 60 mm. We recommend that you make sure the axle width of the trucks matches with the width of the deck.
