Fitment guarantee and VIN verification

Each steering rack undergoes a detailed inspection of the rack teeth condition, the integrity of the rubber boots, and the undamaged condition of the electrical wiring harness sockets.

Fitment tip: Different types of steering racks were fitted to Audi A7 (4K) and A6 (C8) models (depending on the presence of a rear-axle steering system – Dynamic All-Wheel Steering 1N8, or the standard steering system 1N1 / progressive 1N3 / 1N7). Before purchase, we recommend comparing the OE number of the old steering rack or verifying fitment using the vehicle's VIN.
