1226-25 – Weld Yokes – 1251 Series – Butt Dia 2.375″ – Tube Dia Wall 2.500X0.065

The Right Weld Yoke Makes or Breaks the Driveshaft

Driveshaft failures traced back to the yoke weld are almost always a fitment problem -- wrong bore, mismatched series, or inadequate wall engagement. The 1226-25 solves all three: it is machined specifically for 2.500" OD / 0.065" wall steel tube, uses the 1251 series u-joint interface, and provides a 1.750"" center-to-weld dimension that fits standard driveshaft geometry for light-duty import and compact truck vehicles.

Dimensional Data

Construction & Reliability

Heat-treated steel construction delivers the torsional rigidity required for heavy-duty propshaft applications, resisting deflection under load. All bearing pockets are machined to series-standard dimensions so standard 1251 u-joint crosses and snap rings drop in without modification.

Fabrication Best Practices

• Clean and deburr the tube end before inserting into the yoke bore.
• Tack weld at four 90-degree positions before completing the circumferential weld.
• Use ER70S or equivalent filler rated for the base metal (STEEL).
• Post-weld, check TIR at the u-joint seat -- reject if above 0.005".
• Dynamic balance the complete shaft assembly before vehicle installation.

Application Suitability

The 1251 series is widely used on light-duty import and compact truck platforms. Verify that the mating transmission output, transfer case, or differential input uses the same series to avoid cross-series incompatibility at the u-joint interface.
