N.º de parte 3-4-8051-1 Yugo de extremo, serie 1480, Diám. de estrías 1.774", Diám. de cubo 2.500"

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.

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.
