2726-203 – Tri & Quad Prongs – Bolt Circle Dia 78MM – Butt Dia 1.844″ – Face To Weld 1.125

2726-203 Tri & Quad Prong Weld Flange — BMW Application

The 2726-203 is a tri/quad prong weld flange for BMW driveshafts, built around a 78MM bolt circle with 10MM bolt holes. The butt diameter is 1.844" and the face-to-weld dimension is 1.125". Centering is handled by a 28MM nose bushing, and the weld end fits a 2.000" OD x 0.083" wall tube. The smaller 78MM bolt circle places this part in a different BMW fitment range than the 96MM 2726-series variants.

When fitting the 2726-203, verify the BMW companion flange carries a 78MM bolt circle and 10MM bolt holes — do not interchange with the 96MM bolt circle 2726-251 or 2726-250. The 1.844" butt diameter is specific to smaller BMW shaft tubes; confirm tube OD is 2.000" and wall is 0.083" before proceeding with the weld. The 2726-203 shares the 28MM nose bushing with the 2726-251 but operates on the narrower 78MM bolt circle, making it suited to compact BMW rear axle configurations. Cross-reference the OE companion flange bolt circle before ordering.
