Center Tunnel Mounting Bracket / Support Frame – 4K0863051A

Original mounting bracket / center tunnel support frame (lower bracket for mounting the center tunnel and armrest to the vehicle floor panel), designed for Audi A7 Sportback, S7 and RS7 (4K / 4K8 generation) and Audi A6 C8 (type 4K2 / 4K5 / 4KA) models produced from 2018 to 2026, including versions with 3.0 V6 TFSI (55 TFSI), 2.0 TFSI (40/45 TFSI), TDI engines, and top-tier S and RS models based on the modular MLBevo longitudinal platform.

Original VAG interior structural and load-bearing component. Made of durable stamped structural steel alloy / hardened engineering plastic with high resistance to static loads, longitudinal pressure, and body vibrations. Mounted directly to the floor tunnel sheet metal. Ensures a stable, rigid, and rattle-free fit for the entire center console frame, armrest storage compartment, guide rails, and tunnel side panels, preventing trim sagging, plastic creaking, and vibrations during daily use.

Fitment guarantee and VIN verification

Each frame undergoes a detailed inspection of the mounting surfaces for any deformation and is thoroughly cleaned before shipping.

Fitment / installation note: The base designation 4K0 863 051 A (interior and center tunnel group 863) is the main anchor for attaching the center console to the floor in the MLBevo platform. Replacing this component may be necessary during comprehensive interior repairs, center tunnel trim replacement, or after side collisions that have warped the load-bearing points. The original OEM bracket ensures that the console is perfectly flush with the dashboard and floor without gaps or unwanted noises when pressure is applied with the elbow. Before purchasing, we recommend comparing the OE number stamped on the part or verifying it using the vehicle's VIN.
