O-Rings For Your Fingerboard Trucks O-rings are one of those small upgrades people notice straight away. They sit between your bushings and washers and help smooth out the feel of your trucks, reduce rattling, and give your setup a more controlled response. For riders who like looser trucks, they also help stop over-tightening while still keeping things stable. They’re especially useful for protecting softer bushings from getting crushed over time, which means your setup lasts longer and feels more consistent session after session. Whether someone likes technical tricks, heavy turning, or just wants their board to feel less twitchy, O-rings are an easy and affordable upgrade that changes the feel without replacing the whole setup. The new Radical Fingerboards O-rings are made for fingerboard setups specifically — simple, durable, and designed to make your trucks feel smoother.
