2-3-10201X Transmission Yoke 1330 Series, Splines Count: 30/31 Splines Inside Dia: 1.391 Hub Dia: 1.886

2-3-10201X Dana Spicer 1330 Series Transmission Slip Yoke — 30/31 Splines x 1.391" Diameter

The 2-3-10201X is a Dana Spicer 1330 Series transmission slip yoke engineered for Ford applications using 30/31-spline output shafts. It mounts directly onto the splined output shaft of transmissions and transfer cases — including the Ford 4R100, NP208F, BorgWarner 1356, and 1345R — and telescopes on that shaft as the driveshaft changes length during suspension travel. The 1330 Series yoke accepts U-joint caps measuring 1.062" in diameter. Cross-references include Neapco N2-3-10201X. The "X" suffix denotes a greaseable design with a zerk fitting for field lubrication.

The spline specification for the 2-3-10201X is 30/31 splines at 1.391" inside diameter — the 30/31 designation reflects a Ford-style spline count that is catalogued interchangeably across certain model years. The hub diameter of 1.886" controls the seal fit at the transmission or transfer case tailhousing; installing a yoke with an incorrect hub diameter will either fail to seal or damage the tail seal lip. The center U-joint to end dimension of 7.000" defines the overall yoke length from U-joint cross centerline to the end of the spline bore — this is the telescoping slip distance available when the yoke is at its nominal engagement depth.

Fitment & Installation Notes

Before ordering the 2-3-10201X, count the splines on the transmission or transfer case output shaft and measure the shaft's spline minor and major diameters. The 30/31-spline count is specific to certain Ford output shaft configurations — do not assume this yoke fits simply because the application is a Ford vehicle. Verify the hub diameter of 1.886" is correct for the tail seal in the specific transmission model being serviced; Ford used different hub diameters across model years and transmission variants. The counter bore diameter is listed as 0, indicating no stepped bore — the spline bore is consistent from entry to end.

The 1330 Series sits one step above the 1310 in the torque capacity hierarchy and is commonly found on 3/4-ton and 1-ton Ford truck applications where the additional yoke ear width (3.625" vs. 3.219" for 1310) provides a longer U-joint cross for improved torque handling. Both 1310 and 1330 use the same 1.062" cap diameter, but U-joints are NOT interchangeable between the two series due to the different ear span. The 2-3-10201X greaseable design ("X" suffix) requires periodic greasing through the zerk fitting to maintain cap and needle bearing lubrication — sealed yokes are maintenance-free but non-regreaseable.

The 2-3-10201X is the catalogued Dana Spicer part number for this Ford-specific 30/31-spline, 1330 Series slip yoke. Neapco lists the equivalent as N2-3-10201X. When installing this yoke on a 4R100 or NP208F application, confirm the output shaft spline count, hub diameter, and tail seal dimension against the service manual specifications.
