These help a lot if you need extra clearance with bigger wheels or just want a little more turn/stability out of your trucks. You will add 7 degrees or lower 9 deg depending on which way you set it up. 9 degrees is good for most wheels up to 74mm, for 75mm+ we highly recommend the .50” riser. This package comes with 1 set for 1 truck! It will turn a 50 deg truck to 59 or to 41 deg.
