Mugen MBX7R Eco Buggy / Truggy Bearing Kits. This kit was developed with the assistance of our Team Drivers. We found that Ceramic wheel bearings do not last as long as steel bearings, due to the hardness of ceramic balls and the conditions that wheel bearings endure, premature wear of the steel rings was found to be common in comparison to our V2 Premium Steel Bearings.
