Detailed Description

KYB 341720 is engineered for drivers replacing worn front struts on Audi models with standard or sport suspension configurations listed in the fitment data. It is designed to restore the original ride control that affects braking stability, lane-change response, and overall handling. For Audi A4 and A4 Quattro front suspension service, as well as Audi A5, A5 Quattro, S4, S5, and Q5 front applications, this Excel-G strut follows OE-style damping calibration and uses quality components consistent with KYB’s OEM supply background. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. The part number 341720 is commonly searched for front strut replacement on Audi platforms, and KYB 341720 is a direct-fit option for the listed vehicles and configurations.

What It Helps Address
