Pro Tip:

When hubs are in the lowest position, clearance on the arm may be necessary for the X-Duty Bell to rotate freely. Best to use a sanding drum to clearance the plastic arm. (check out photo with wrench pointing to area). Use MIP Grease and Loctite upon assembly. Be sure to keep joints lubed to enjoy long part life. Front Traxxas 12mm Hex Conversion : 1 x TRA1654.
