Independent Genuine Parts Standard Cylinder Bushings

A 90A durometer is considered a medium-hard rating. It offers a balanced feel that is stable enough for street skating but still soft enough to allow for responsive, snappy turns.

These are designed specifically for Traditional Kingpin (TKP) trucks, which are standard on most street and park skateboards. They will not fit Reverse Kingpin (RKP) trucks typically found on longboards.

You should replace your bushings if you notice your board feels 'mushy' or unresponsive, if the truck feels like it's leaning to one side, or if the urethane has visible cracks and crumbling edges.

Barrel bushings generally offer more resistance and stability than conical shapes because they have more surface area. If you are coming from softer or conical bushings, you will likely notice a more precise, centered feel that resists wheel bite during deep carves.

Like most urethane components, these will feel slightly stiff right out of the package. They typically reach their optimal performance feel after a few sessions of riding as the urethane settles into your truck seats.
