When fitting the 3526-4121 on a Dodge Sprinter, confirm the driveshaft tube is 3.000" OD with 0.083" wall before welding — the larger tube spec compared to the 2.500" variants is specific to this heavy van platform. The THRD 12x1.5 bolt holes require M12 fasteners at 1.5mm pitch; confirm pitch against the companion flange hardware. The 3526-4121 and 3526-4120 are the two 120MM bolt circle variants in this series, covering Dodge Sprinter and Mercedes Sprinter respectively. Both use the 2.844" butt diameter and 3.000" x 0.083" tube spec; the face-to-weld differs slightly (1.638" vs 1.634") and the bolt holes differ (THRD 12x1.5 vs 12MM clearance). Confirm the Dodge Sprinter application requires the 1.638" face-to-weld and threaded holes.
