Gray & White Swirl Pro Duro Bubble Bushings are the tuning knob of your setup: custom-molded silicone that drops into your trucks and sets exactly how the board leans and turns. This colorway comes in two firmness levels: 51A and 61A. Each pack includes 5 bushings: each truck uses 2, so one pack tunes both trucks with a spare.

Details
What a bushing actually does
The bushing is the soft piece your kingpin runs through, and it decides how freely your trucks lean and turn. Softer carves easier and reacts to small inputs; firmer holds its line and feels locked-in on landings. This is the real tuning knob, not the kingpin nut you crank down.
Consistent by design
Every bushing is custom molded from an ultra-premium silicone with a consistent shape and hole placement, so each one feels exactly like the last. Same bubble profile riders already know.
Designed after real skate bushings
The shape takes after conical skateboard bushings, scaled down for fingerboard trucks. That conical profile gives a smooth, progressive lean.
Compatibility & Fit
Fits all major fingerboard truck brands, including wider-kingpin trucks like Dynamic and Y-Truck.
Designed in the US, made from imported parts.
Frequently Asked Questions
Which durometer should I pick?
Start with the turn you want. 51A is the looser of the two, the most responsive tuning we offer. 61A is the firmer of the two, the same feel as our OG bubble bushings.
Does this actually change how my trucks turn, or do I just adjust the nut?
The bushing is what changes the turn. The kingpin nut adds a little tension, but the bushing durometer is what sets how the truck actually feels.
Will these fit my trucks?
They fit all major fingerboard truck brands, including wider-kingpin trucks like Dynamic and Y-Truck.
How many bushings come in a set?
Five per pack. Each truck uses 2, so one pack tunes both trucks and leaves you a spare.
Are these safe for a younger kid?
These are small parts and a choking hazard, so they're not suitable for children under 14.
What does the Teak Guarantee cover?
Free replacements for parts that are broken during shipping or initial setup. Contact Teak Tuning with a photo of the issue.
