Pro Duro Bubble Bushings are professional shaped bushings for your fingerboard trucks. Each set is molded from an ultra-premium silicone material with a consistent shape and hole placement on every single bushing.
Here’s everything you need to know about installing your fresh set of Pro Duro Bubble Bushings:
Step 1: Remove the current tuning
Use a tool to remove the locknut, then remove the hanger and current tuning.
Tip: Be careful when removing the lock nut. Since it’s so tiny, it is incredibly hard to find if it is dropped on the floor or carpet.
Step 2: Install the bottom bushing
Place a Bubble Bushing onto the axle. The smaller side should be at the bottom of the axle. Tim Keefe
Step 3: Place the hanger
Once the bottom bushing is on the axle, place the hanger back onto the axle.
Step 4: Install the top bushing
Place the bottom bushing on the axle. The wide side should face the hager and the thinner side should be at the top of the axle.
Tip: The wide sides of the Bubble Bushings should be facing each other on the axle.
Step 5: Install the lock nut
Use your tool to screw the lock nut back onto the axle.
Step 6: Complete your setup
Repeat steps 1-5 for the other truck, Once your new tuning has been installed
Tip: Do NOT overtighten the lock nut. When a lock nut is over tightened, any tuning you use will not last as long.
