OE 1122000970 — Belt Tensioner for Mercedes-Benz

Build-year coverage is listed row by row in the Applications table above. Where several generations share one number, the newer rows usually carry a revised suffix — compare the last four characters before buying, since a suffix change often means a different connector or bracket.

Start from the code cast or printed on the part you are removing — that is the authoritative source. If it is illegible, use the Applications table on the closest transmission & drivetrain reference and narrow by build year. Send photos and we will cross-check the number for you.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.

Bulk pricing is tiered: 10 pieces, 50 pieces and full-carton quantities each carry a different unit rate. Piece price also moves with packing format and whether your own brand is printed on the carton, so tell us the landed quantity you are planning.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 1122000970 with other transmission & drivetrain references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

KingMay supplies OEM-grade aftermarket parts built to the 1122000970 factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.
