The Teak Tuning Prodigy Swerve Fingerboard Trucks come in at 34mm wide. Their professional shape and appearance paired with the awesome price tag make them a perfect option for all skill levels. These trucks are compatible with dual bearing wheels, but work best with Teak Tuning wheels, or wheels that have single bearings. They're also slightly shorter than other trucks which means that larger diameter wheels may rub on your deck if you ride your trucks loose, or if you're making a tight turn. Finally, the Prodigy Swerve trucks come 100% assembled and include four lock nuts with nylon inserts, eight screws and a standard fingerboard tool!
