Level Up Fingerboard's Beta Bushings are made of urethane rubber and are ideal for loose to medium responsive tuning. They are genuine skateboard bushings, but for your fingers!
Beta Bushings have been tested to work all of the popular nut-style trucks: Black River, Tech Deck, and more.
These bushings are compatible with some trucks using inverted kingpins, Dynamic Trucks (without using the included washers) for example, but are more likely to fit nut-style trucks.
**DO NOT OVERTIGHTEN. These softer bushings are not designed for tight tuning**
