Description
4-28-307-Su Weld Yoke — Steel, 1550 series, fits 3.500×0.095 tube | 3.321″ butt dia | 2.188″ center-to-weld. Professional weld-on replacement. Match tube OD before ordering.
Full Description
Building or rebuilding a 1550 series driveshaft means getting the weld yoke right first. The 4-28-307-SU weld yoke is machined for one tube diameter and one series — those two specs are non-negotiable. Get the butt diameter wrong and the weld joint is already compromised before you strike the arc.
4-28-307-Su Weld Yoke — Tube Fit & Steel Specs
The 1550 series covers commercial fleet Class 5-6 and medium-duty vocational trucks. The 4-28-307-SU weld yoke specs: fits 3.500x0.095 tube | 3.321" butt dia | 2.188" center-to-weld. Steel construction — DOM-compatible, full-penetration weld ready, standard for high-torque driveshaft applications. Center-to-weld dimension is critical for total shaft length calculations — it's the distance consumed by this yoke on that end of the tube.
Measure your tube OD before cutting and welding the 4-28-307-SU weld yoke. Tack it in place first, check runout is within 0.005" before committing to full weld. A slight off-angle tack that gets welded solid will show up as vibration at 50+ mph that no balancer can fully correct.
