Danchuk Front Wheel Hub Roller Bearing Conversion Kit eliminates the old ball bearings and replaces them with modern roller bearings. This is an excellent way to modernize stock wheel applications, and is an absolute must-have if you have custom width wheels. Old-style ball bearings cannot withstand the side loads that custom width wheels transmit to the bearing. You can still use your stock brake drums and you will not notice any changes in front end alignment. Kit comes complete with new hubs, studs, inner bearings, outer bearings, races, grease seals, hub caps and spindle nut washers. Easy to install. Danchuk #138 will work for any model 1955-1957 Chevy.
