Description
3-4-8051-1 — 1480 Series end yoke with 1.774-inch spline bore, 2.500-inch hub, and BS snap ring retention. Drop-in replacement for 1480 Series output shafts.
Full Description
The 3-4-8051-1 end yoke from UDS is defined by its precise dimensional stack: 1.774-inch spline diameter, 2.500-inch hub, and a center-U-joint-to-end measurement of 4.469". These numbers must match your output shaft exactly -- a fraction of an inch off means the yoke will not fit or will fail prematurely.
Full Specification Breakdown
Selecting this yoke requires cross-checking every dimension against your application. The specifications below represent the actual machined dimensions, not nominal values. Measure your existing yoke or output shaft before ordering.

| Spline Diameter | 1.774" |
| Spline Count | 34 |
| Hub Diameter | 2.500" |
| Center U-Joint to End | 4.469" |
| Through Hole Diameter | 2.250" |
| Snap Ring Style | BS |
| Brand | UDS |
Snap Ring and Retention System
This yoke uses a BS design, which dictates the U-joint cap retention method. 1480 Series applications overwhelmingly use this style due to its serviceability and load rating. When replacing a worn yoke, the snap ring style must be preserved -- mixing OSR and ISR yokes with mismatched U-joints leads to cap ejection under torque.
- Retention style: BS
- Through bore ID: 2.250" -- critical for shaft clearance
- Hub OD: 2.500" -- registers against companion flange or seal bore
- Application notes: 1480 Series standard fitment
Why Dimensional Accuracy Matters
In driveshaft engineering, yoke geometry directly controls phasing, balance, and operating angles. A yoke with oversized spline bores will develop rotational slop that amplifies vibration at highway speed. Undersized bores damage output shaft splines during installation. The 3-4-8051-1 is manufactured to match the 1480 Series standard, which is also the OEM specification for the vehicles in this application class.
For high-torque applications -- diesel pickups, off-road builds, and towing rigs -- always upgrade to a forged yoke in the appropriate series rather than reusing worn stock components.
Part 3-4-8051-1 is a UDS product. Universal Driveshafts stocks a complete range of 1480 Series end yokes, U-joints, and driveshaft components. Contact our technical team for fitment assistance.
