The part is built to the following specification: Fitting Position: Rear Axle, Brake System: LUCAS. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. Compatible with MERCEDES-BENZ vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 109-1881, 1881Q, 1987474775, 420186 and 6 more. Matching these numbers confirms a like-for-like replacement with no loss of function.
