This fender extension is an original Claas component that bridges the gap between the fender panel and the adjacent bodywork on the host tractor. It is a five-hole panel that mounts in the fender area, providing a continuous surface that prevents debris ingress into the cab or chassis cavity. A missing or damaged extension allows dirt and moisture to accumulate behind the fender, which can lead to corrosion of the mounting brackets and wiring harness connectors. Because this is an original part, its hole pattern and contour match the fender stamping exactly, so no drilling or panel modification is needed during replacement.
