Heavy-Duty Driveline Yokes for Trucks, Trailers & Equipment

Yokes may seem like small components in the driveline system, but in heavy-duty truck, trailer or service-body builds they play a critical role in torque transfer, drive-shaft alignment, and system durability. At Custom Truck One Source we provide rugged yoke assemblies — including slip-yokes, end-yokes, weld-yokes and flange-yokes — built for Class 6-8 trucks, flatbeds, equipment trailers and vocational builds where reliability and uptime matter.

Why the Right Yoke Matters

In a commercial-vehicle driveline, yokes ensure proper fit-up, smooth rotation, minimal vibration, and alignment across the driveshaft, universal joints and axle. According to driveline specialists, a yoke “is a simple torque input and output piece… typically the hub diameter of the stub locates the mating part, which is typically a tube.” Installing a mismatched or underspec’d yoke can lead to excessive vibration, wear on U-joints, mis-alignment, premature failure and increased maintenance costs.

Key Specification & Fitment Criteria

When selecting a yoke for your truck, trailer, body build or driveshaft assembly, consider:

• Series and size: Heavy-duty vehicle driveline yokes must match the driveshaft series (e.g., SPL, RPL, 1610) and bearing cap size.

• Slip-yoke vs weld-yoke vs flange-yoke: Slip-yokes accommodate length change and axial movement; weld-yokes are fixed for tube-to-tube connections; flange-yokes provide bolted interface to differential or transfer case.

• Material & construction: For heavy-duty use expect forged or heavy-cast steel, precision bearing seats, proper hub diameters and alignment surfaces.

• Mounting/fitment: Ensure bolt-circle, hub diameter, spline counts and bearing cup fit match your driveshaft/hub assembly.

• Service environment: Heavy vocational, off-road or trailer duty places extra demands on yokes — consider vibration, misalignment, frequent articulation and maintenance access.

Benefits for Fleet, Body-Builders & Trailering Operations

Selecting the correct yoke leads to tangible operational advantages:

• Reduced vibration, smoother driveshaft operation and less wear on U-joints and bearings.

• Fewer drivetrain failures, breakdowns and unplanned downtime — leading to higher uptime.

• Simplified parts inventory when you standardize on yoke specs across your builds or fleet.

• More predictable rebuild cycles, lower overall maintenance cost and better vehicle/resale value.
