2726-251 – Tri & Quad Prongs – Bolt Circle Dia 96MM – Butt Dia 2.375″ – Face To Weld 1.125

2726-251 Tri & Quad Prong Weld Flange — BMW Application

The 2726-251 is a tri/quad prong weld flange intended for BMW driveshaft applications. It mounts to a 96MM bolt circle using 12MM bolt holes and centers via a 28MM nose bushing diameter. The butt diameter measures 2.375" and the face-to-weld dimension is 1.125", positioning the flange face relative to the weld zone on a 2.500" OD x 0.065" wall tube.

When fitting the 2726-251, confirm the companion flange on the BMW differential or gearbox carries a 96MM bolt circle and accepts 12MM fasteners. The 28MM nose bushing centers the assembly during torquing; a mismatched nose diameter will introduce runout. Verify tube OD and wall thickness match 2.500 x 0.065 before welding — wall deviation affects weld penetration and rotational balance. The 2726-251 is dimensioned specifically for BMW driveshaft geometry where the 1.125" face-to-weld measurement governs the axial position of the flange relative to the tube end. Cross-check this dimension against the OE shaft length before committing to weld.
