Chose between the "High Rollers" and "Low Pros". When purchasing a set of trucks, it will come with a set of pucks and king pins. 

The High Rollers offer a taller, yet stable, ride and are suggested for our 169cm "Black Sheep" ski or our 156cm "STFU" (Shred The Fluff Up) powder ski and the 152cm "Bad Unicorn".
 
The Low Pros are lower and offer a quicker pop reponse time. These trucks are suggested for our brand new 138cm "Hare Raiser", 138cm "The Sorcerer" and the "152cm Bad Unicorn"
