N2-81-1181 – Yoke Shafts – 1310 Series – 1.378″ Splines dia – 32 Spline

The N2-81-1181 yoke shaft is an integrated assembly — splined shaft on one end, u-joint yoke on the other. It splines onto the output shaft and carries the u-joint cross simultaneously, in one part. For 1310 series applications, both the spline specification and the u-joint series have to be correct. One wrong dimension on either end and the part doesn't work.

N2-81-1181 Yoke Shaft — 1310 Series Spline & CL Specs

The 1310 series covers light-duty trucks — F-150, Silverado 1500, Jeep Wrangler, Ram 1500. The N2-81-1181 yoke shaft specs: 1.378" x 32 spline | 3.500" spline length | 0" CL-to-end. This part has a 2" Pilot and 3" BC.. Spline length determines engagement depth — short engagement under high torque loads damages the output shaft, not just the yoke shaft. CL-to-end positions the u-joint cross relative to the output shaft face; this affects clearance on tight installations.

Verify both ends of the N2-81-1181 yoke shaft before installing: spline count against the output shaft, and series cross size against the driveshaft u-joint. If either is wrong, the part has to come back out. Measure once, order correctly.
