NOTE: 8mm x 10mm spacers will fit almost all standard longboard wheels. If you are using 10mm axle trucks, you will need different spacers!
If you have been considering adding longboard skateboard bearing spacers to your longboard, you should read the following:
Adding spacers in between your bearings will align the bearing to the inner hub of your wheel. This will effectively reduce friction and movement inside the hub of the bearing. With spacers installed, the energy between turns is absorbed by the wheel and not the bearing itself, reducing impact and side load on the be bearing itself.
Reducing stress on your bearing components will help prevent your bearings from exploding or seizing up while riding your longboard. In addition to stress reduction, adding spacers will hold your wheels steady on your trucks during slides, preventing that annoying and sometimes dangerous choppiness experienced when sliding square-lipped wheels. Ultimately, you will have a bearing that will endure the demands of a downhill racer or freerider.
If you are doing any Racing, Downhill, Freeride, and especially Slides and hard carves, you will want to add Bearing Spacers to your Longboard Skateboard.
