Original WaveCam bushings (per 2 trucks)
The flux capacitor of every Original longboard truck is the patented WaveCam. The WaveCam allows Original trucks to use a single spring, as opposed to multiple springs, as resistance. That single spring design means that there are no worries about tightening two springs evenly as well ensuring upgrades and repairs are quick and easy.
Although WaveCams are generally very sturdy, it is possible to greatly reduce their life expectancy by over tightening your Original trucks.
