Our innovative RJ Slim-Line Wheelie Bar Wheels are made of high strength polyurethane and feature a width of only 1-1/4" at the hubs, and a slim tread width .500". The combination of slim tread width and shielded ball bearings gives these wheels less rolling resistence than any other wheelie bar wheel on the market, an exclusive RJ Race Cars design.
Removable hubs allow for easy access to the bearings. Wide bearing hubs (410433-1) are also available to allow these wheels to be used with standard 1-5/8" wide wheel housings. Sold in pairs.
