Description
4-4-1901-1 End Yoke — 1550 series, 1.750 x 10 spline | 2.625″ hub dia | 4.672″ CJ-to-end | 2.234 bore. Premium replacement, spline-specific fit. Count splines before ordering.
Full Description
The 4-4-1901-1 end yoke connects the driveshaft end to the axle or transfer case output shaft via a splined bore. Spline count and diameter are the critical dimensions — a mismatch here means the yoke either won't engage the shaft or will engage loosely and spin out under load. The 4-4-1901-1 end yoke is machined to one specific spline specification for 1550 series applications.
4-4-1901-1 End Yoke — Spline Specs & 1550 Series Fitment
The 1550 series covers commercial fleet Class 5-6 and medium-duty vocational trucks. The 4-4-1901-1 end yoke specs: 1.750 x 10 spline | 2.625" hub dia | 4.672" CJ-to-end | 2.234 bore. MIDSHIP YOKE. Hub diameter is the outer dimension that clears the axle housing or T-case bore. CJ-to-end determines how the u-joint positions relative to the flange or seal surface. Count the splines on your output shaft — don't go by the vehicle model alone. Axle swaps and rebuilds can change the spline count from the original. The 4-4-1901-1 end yoke is dimensioned for one spline specification; putting it on the wrong shaft will damage both the yoke and the shaft.Key Features
