Advantage Racing Products Ball Bearings were used to win two ROAR National Championship Titles in 2013!;Ceramic Bearings are a Great Performance Upgrade! Improves driveline efficiency, acceleration, mileage, weight, unsprung weight, and more! Ceramic Ball Bearings are up to 40% lighter than Standard Ball Bearings. Due to their light weight, less centrifugal force is placed on the outside bearing race as the bearing spings, reducing heat, wear, and skidding. This results in a much more efficient bearing, which will have a longer life, spin more freely, and spool up faster!;Metal Shielded Ball Bearings do not have as much protection as Rubber Sealed bearings, and are at risk for exposure to dust, dirt, and moisture, which can destroy bearings. These bearings offer maximum efficiency, but minimum protection from the elements. Use these bearings in areas where exposure to dirt, dust, and moisture is not likely (gearboxes, etc);Our ball bearings are OUTSTANDING, and over 100,000 bearings have been sold (under CRC Racing and Advantage Racing brands) to satisfied racers all over the world! These Ball Bearings have been trusted and run by some of the fastest racers in the US and around the world!;Includes two (2) Ball Bearings.
