Part No. 3126-25CF Weld Yokes, 1310 Series, Butt Dia 2.500", Tube Dia Wall 2.780X0.180

3126-25CF Weld Yoke -- 1310 Series, 2.500"" Butt Diameter

The 3126-25CF is a precision weld yoke designed for 1310 series driveshafts. With a butt diameter of 2.500"" and tube compatibility of 2.780X0.180, this component integrates directly into custom or OEM-spec propshaft builds. The aluminum alloy body ensures long service life in demanding drivetrain environments.

Dimensional Specifications

Series Compatibility

The 1310 series u-joint interface (cap diameter 1.062") makes this yoke suitable for light truck, SUV, and street performance applications. When pairing this weld yoke with a u-joint, verify that both components share the same series designation to ensure proper cap pocket engagement and retention clip compatibility.

Tube Fitment

This yoke is manufactured to accept tubing with an outside diameter of 2.780" and a wall thickness of 0.180". Before welding, confirm that the tube OD matches the butt bore precisely. A gap exceeding 0.005" between tube and yoke bore can introduce weld porosity and reduce joint fatigue life. Use a V-groove or fillet weld with full penetration; partial welds are not acceptable for rotating driveshaft components.

Material & Finish

Aluminum construction cuts rotational mass significantly, a key advantage for high-RPM driveshaft assemblies where unsprung weight matters.

• Material: ALUMINUM
• Weld prep: machined to close tolerance for consistent gap
• Balance: suitable for dynamic balancing post-weld
• Surface: raw machined; paint or coat as required for corrosion protection

Installation Notes

Align the yoke ears parallel to the mating yoke ears before tacking. Weld in a balanced sequence (opposing passes) to minimize heat distortion. After welding, re-check runout -- total indicator reading (TIR) should be under 0.005" at the u-joint seat. Dynamic balance the completed assembly to OEM specifications before installation.
