Technical Notes: New 11.5" gears have 2.125" / 2.000" pinion journals. The small bearing design gears with 2.000" / 1.625" pinion journals can be used with this conversion kit
All of our bearing kits come with either Koyo or Timken bearings, which would be made in Japan or USA. Although Timken does have very few made in other places. Both companies are tier 1 OEM suppliers.
