COMPATIBILITY
Knuckles are compatible with most reverse-kingpin longboard trucks (including Paris V2 and V3, Bear, Randal, Carver, Gullwing, Tracker, Caliber, Atlas, Bolzen, Aera, Rogue, PNL, Ronin, etc).
They DO NOT work on any traditional kingpin (street) trucks, such as Independent trucks or Paris Street Trucks.
If your truck is not on this list it may not be compatible, so please check the measurements and compare with your current bushings.
INSTALLATION
In the standard configuration, the insert barrel is placed on the bottom or board side (insert oriented toward the truck hanger) and the gumdrop on the top or road side (smaller/rounded side toward the washer).
Also try double insert barrels (the height of the insert is half the thickness of a Paris bushing seat) or double gumdrops. Replace the included cup washers with flat washers for a less restrictive, more linear turning rate.
