The Bilstein B6 24-069052 is a front monotube gas-pressure shock for the W211-chassis 2003 Mercedes-Benz E320 Base Sedan. The manufacturer describes the B6 as a bolt-on upgrade, tuned firmer than OE, that sharpens control and grip on your existing springs, at the original ride height. The manufacturer also credits its monotube design with a 63% larger working piston for sharper damping. For an E320 owner who wants more composed handling without lowering the car or moving to coilovers, this is a practical step up from worn stock dampers.
Check your vehicle before ordering. This part is listed for standard chassis; without Airmatic DC, so Airmatic-equipped cars need a different front unit. Keep the front and rear part numbers straight, since there are different part numbers for front (24-069052) and rear (24-069069). The front unit is a spring-bearing design, so the job involves compressing the coil spring, which makes it a more involved install than a rear damper swap.
No. The manufacturer states the B6 is designed to work with the existing springs at the original ride height, so a spring change is not required.
No. Owners on user forums note that the front is 24-069052 and the rear is 24-069069, so confirm the position before ordering.
This is a moderate-difficulty job. Owners who have documented the front replacement on this chassis report about six hours of work, with 13mm, 17mm, and 21mm sockets and a spring compressor on hand. The 17mm fastener that holds the spring and shock assembly together is recessed in the upper shock mount, and Mercedes uses a special socket with a separate tool to hold the shock shaft still while you remove it. Expect the lower control arm to drop a little when the shock is out. Owners on user forums also warn that if the bolts are tightened before the car is lowered down, the suspension may brace, which can change the final ride height. Tighten the mounting hardware with the car sitting on its wheels.
