3R26-35 – Weld Yokes – 3R Series – Butt Dia 3.383″ – Tube Dia Wall 3.500X0.065

Shop Notes: 3R26-35 -- 3R Weld Yoke, 3.383" Butt

If you are on the floor building a custom driveshaft and need a 3R series weld yoke to accept 3.500" OD x 0.065" wall tube, the 3R26-35 is your part. Butt diameter is 3.383", center u-joint to weld face is 1.940"". Material is steel. It ships machined and ready to weld -- no cleanup bore required.

Spec Sheet

Tube Compatibility Check

The bore is machined for 3.500" OD tube at 0.065" wall. Using a different tube OD -- even 0.020" off -- will cause a loose fit that traps weld gas and weakens the joint. If your tubing is metric or slightly non-standard, measure with calipers before ordering.

Series Interface

The 3R series u-joint pockets match standard -- cap-diameter crosses used in driveshaft drivetrain applications. Using a different series yoke at the other end of the shaft is fine as long as the mating u-joint is also a cross-series design -- but keep both ends consistent when possible for balanced angularity.

Welding & Balancing

Heat-treated steel construction delivers the torsional rigidity required for heavy-duty propshaft applications, resisting deflection under load. After welding, spin-balance the shaft assembly to at least 0.25 oz-in residual imbalance per balancing plane -- less for high-RPM or highway applications.
