Description
3-3-1621KX slip yoke — 1480 series (Spicer). 2.250″ x 10 spline. CL-to-end: 3.719″. Max joint angle: 8.0″. Lube fitting: 500174-1.
The 1480 series is rated for significantly higher torque than the 1350 and 1410, with a cap diameter of 1.375". The 3-3-1621KX is a genuine Spicer-brand slip yoke for this series, confirmed by the Spicer brand attribute. The 2.250" spline bore at 10 splines is an unusual combination that appears on specific heavy-duty transmission and transfer case applications.
Spicer provides specific service part numbers for this yoke: slip yoke plug 3-68-93 (closes the spline bore end to retain grease) and lube fitting 500174-1 (the grease fitting for lubrication). These parts indicate this is a greaseable slip yoke, meaning periodic lubrication is required during service intervals. Non-greaseable slip yokes require no service but this style does.

The 8.0 degree maximum angle rating is important for installation planning. Operating a 1480 slip yoke consistently above its angle limit accelerates wear on both the slip interface and the U-joint trunnions. The short 3.719" CL-to-end suits applications where the slip travel is limited.
