Teak Tuning - Bubble Bushings Pro Duro - 51a

51a - Extra Loose
The most responsive tuning we offer, with the widest range of truck movement. Carve-everything territory.

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.
