Strut Bar / Front Suspension Reinforcement Bracket – 4K0801223A

Original front suspension strut bar (strut bar / reinforcement bracket for the shock tower and bulkhead), designed for Audi A7 Sportback (type 4K / 4K8) and Audi A6 C8 (type 4K2 / 4K5) models with 3.0 V6 TFSI (55 TFSI) petrol and 3.0 V6 TDI diesel engines.

Factory-fitted stiffening element for the VAG group body structure. Made from a lightweight, high-strength aluminum alloy with a precisely engineered cross-section. It connects the front shock tower to the bulkhead and longitudinal beams, increasing the torsional rigidity of the front body section. It provides more precise handling in corners, stability at high speeds, and optimal operating geometry for the multi-link front suspension in dynamic MLBevo platform models.

Fitment guarantee and VIN verification

Every part undergoes rigorous quality and geometry checks before shipping.

Fitment / installation tip: The aluminum strut bar is directly responsible for the torsional rigidity of the engine compartment and the proper maintenance of suspension geometry. Installation of the original OEM part guarantees a perfect fit with the shock tower studs and body mounting points without any stress. Before purchasing, we recommend comparing the OE number with the index (A) stamped on the old bracket or verifying fitment using the vehicle's VIN.
