Bilstein B4 Shock Absorbers 45-248573 – Audi A6, A8

Bilstein B4 OEM Replacement shock absorber for the Audi A8 D4 and A6 C7 — Bilstein Shock Absorber 45-248573.

Specifications

• Type: Gas Pressure
• Series: B4 OEM Replacement

Performance

B4 is Bilstein's OE-replacement damper: valving matched to the car's original specification so ride height, body control and comfort return to how the vehicle left the factory. Nothing is uprated and nothing is lowered — it is the right choice when worn dampers have made the car float, bounce or wander, and you want factory behaviour back rather than a firmer setup.

Fitment

Fits Audi A8 D4 (4H2, 4H8, 4HC, 4HL), 11/2009–11/2019, FWD and Audi A6 C7 (4G2, 4GC), 11/2010–11/2019, FWD — see the full list below. Verify fitment using the vehicle compatibility checker above.

What's Included

One Bilstein B4 damper unit — a single shock absorber, not a pair and not an axle set. Order two to do an axle, four for the whole car. Bump stops, dust covers, top mounts and fixings are not included.

Warranty

Backed by Bilstein's manufacturer warranty against defects in materials and workmanship. Cover assumes correct installation, the correct tightening torques, and serviceable bump stops and dust covers. A damper run without its protection parts will be scored by road grit — that is wear, not a defect.
