Fitment guarantee and VIN verification

Each floor bracket undergoes a detailed physical inspection to check for fatigue microcracks and a check of the mounting points before dispatch.

Fitment / installation tip: The initial 4K8 designation (luggage compartment body group 813) confirms that it is profiled exclusively for the shape of the cargo hold floor in the Audi A7 Sportback. The component can be damaged or broken by carrying extremely heavy loads at a single point or during careless removal of the luggage compartment side panels. A broken bracket causes the floor to sag and produces annoying rattling noises. Using an original OEM component restores factory load-bearing capacity and ensures the carpeting fits flush. Before purchase, we recommend comparing the OE number on the part body or verifying it using the vehicle's VIN.
