hey friends..i'm rebuilding the subframe on my max 2, adding some new, improved features such as : 1 1/2 '' axles , front and rear axle plates that will be adjustable to take up chain slack ( no tensioners needed ) and quick release of all axles as as unit ( axle , bearings , sprockets , hubs ) for easy repairs on the workbench and easy reinstalling. i am videoing the build as i go so i can share it with you later . thanks , johnboy va.
