  • For a rebuilt or swapped transfer case, match the bearing already in the unit: open, 35 × 80 × 21 mm.
  • The retaining snap ring is not supplied.

Should You Buy the Bearing or Service Bundle?

Nachi Transfer Case Input Bearing — Best for Replacing Only the Bearing

Choose this bearing when the input gear and other transfer case parts are still serviceable.

Sumo Gear Input Gear + Bearing & Gasket Service Bundle — Best for Replacing a Matching 23-Spline RF1A Input Gear Too

Choose the service-bundle configuration when your RF1A build also needs its matching 23-spline, 2.28:1 input gear and overhaul gaskets. It is not a direct gear replacement for an unchanged 21-spline setup.

Our Recommendation: Buy this bearing for a bearing-only repair. Choose the Sumo Gear service bundle only when the matching 23-spline input gear and overhaul gaskets are also needed.

What's Included
