When fitting the 3526-4120 on a Mercedes Sprinter, confirm the driveshaft tube is 3.000" OD with 0.083" wall before welding. The 12MM clearance bolt holes and 18mm pilot diameter must match the Mercedes Sprinter companion flange. The 3.000" tube spec is consistent with the commercial van driveshaft diameter. The 3526-4120 and 3526-4121 (Dodge Sprinter) share the 120MM bolt circle, 2.844" butt, and 3.000" tube. The key differences: 3526-4120 uses 12MM clearance holes (1.634" FTW) versus 3526-4121 threaded 12x1.5 (1.638" FTW). Confirm the Mercedes Sprinter requires clearance bolt holes and the 1.634" face-to-weld before ordering.
