Detailed Description

Bilstein 19-019680 is a rear suspension shock absorber designed for Audi vehicles that use standard suspension and OE-style mounting points. It is listed for 1988-1992 Audi 80 rear, 1988-1989 Audi 90 rear, 1980-1987 Audi 4000 rear, and 1981-1987 Audi Coupe rear. This makes it a strong fitment-based search match for drivers seeking a rear shock absorber for Audi 80 rear suspension, Audi 90 rear suspension, or classic Audi 4000 and Coupe rear applications.

The B4 OE Replacement line is intended to maintain the original driving feel of the vehicle while meeting OE-level expectations for fit and function. The twintube design supports controlled damping, and the stem upper mount with eye-style lower mount helps match the factory suspension layout on the listed vehicles. This part number, 19-019680, is also a useful reference when cross-shopping OE-style rear shocks for these Audi platforms.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
