Important Fitment Information
Verify transmission or transfer case output shaft spline count, spline outside diameter, barrel diameter, U-joint series, and centerline-to-end length before ordering.
Important: This slip yoke uses a 30/31 involute spline configuration. The spline design may include a missing spline or blind spot. Verify compatibility with the output shaft rather than relying solely on the number of visible internal splines.
The 2.200" barrel diameter is especially important when confirming proper fitment with the transmission or transfer case seal.
Vehicle applications listed are general references. Always confirm dimensions and driveline configuration before purchasing.
