With ACER Racing's National and World Champion reputation in the high performance ball bearing industry we set out to engineer the best high performance Ceramic Bearing upgrade kit for the Boosted Board from our World Famous Ceramic Nitride Pro Series bearing collection. This bearing kit will allow your Boosted Board to spin smoother, faster & longer and is much more durable than the stock bearings. First we started with our tried and tested Ceramic Nitride Pro Series silicon nitride balls (Si3N4). The same super hard balls that gave us the reputation as "the hardest balls in the industry." These balls are matched for consistent concentricity per set. They are polished using diamonds for a super smooth and shiny finish. Their durability is unmatched by any other ball or material in the industry. With a melting temperature of 2552 degrees F and the best modulus of elasticity in the world, these are the best balls period. We use our special synthetic and American ACER Racing SIN oil lubrication in our ceramic skate bearings which has an extremely wide service temperature range of from -50 to +120 degrees Celsius with an incredible speed factor of 1 million. We integrate our HSR inner ball bearing cage for durability and strength with superior heat resistance at high RPMs. This insures that your Boosted Board will spin faster, longer and more smoothly. We seal our ACER SK8 Ceramic Boosted Board bearings with two no contact grey seals which will resist the elements while allowing simple removal for easy cleaning when necessary. Each seal is embossed with our trademark "ACER RACING CERAMIC" logo to insure that you are receiving the original ACER Racing Ceramic ball bearings. The V1 Boosted Board Bearing kit comes with 10 bearings and the V2 Boosted Bearing kit uses only 8 bearings so it comes with 8 total bearings. Washers and spacers that come with your Boosted Board can be reused.
