Blackriver-Trucks Lock Nuts
One of the most fantastic inventions in fingerboarding trucks, the lock nut keeps your trucks in place even when riding really loose. All Blackriver trucks come with them, but if you need more, or lost some, you can pick up a set of these!
One set contains 6 nuts, enough to do a full set of trucks. These will generally also work with non professional trucks such as the ones in the Wide Trucks Setup Kit, or Dump Trucks from Flatface, or many others - however due to the lack of quality control on these cheap trucks they might not work, so we cant guarantee that compatibility. A lot of the time they'll work fine on cheap trucks though.
NOTE - the setup is shown to demonstrate the usage of the nuts, you get the nuts only.
