Bilstein 26-265452 B4 OE Replacement DampTronic Electronic Adjustable Suspension Shock Absorber

The Bilstein 26-265452 B4 OE Replacement (DampTronic) is a direct factory replacement shock absorber engineered specifically for vehicles equipped with electronically adjustable damping systems. Built to Bilstein's legendary standards, this 46mm monotube gas-pressure shock absorber restores your vehicle's original ride quality and handling while fully meeting or exceeding original equipment specifications.

Unlike many aftermarket alternatives that convert active suspensions to passive ones, the B4 DampTronic retains full compatibility with your vehicle's electronic damper control system. All vehicle-specific parameters — including sensors, control units, and damping characteristic curves — remain completely functional after installation.

Key Features:

• True plug-and-play installation — bolts directly into the factory location with no modifications required
• 46mm monotube gas-pressure design — delivers consistent damping force under any load condition
• Full DampTronic® compatibility — preserves electronic damper adjustment, driving modes, and active suspension control
• Meets or exceeds OE standards — engineered using valve technologies developed in collaboration with OE manufacturers
• Restores original ride characteristics — brings back the factory balance of comfort and dynamic handling
• Hardware included — all necessary washers, bushings, and mounting nuts are provided
• Bilstein Limited Lifetime Warranty — covers defects in materials and workmanship for the life of ownership

Each unit is sold individually. For best results, it is recommended to replace shock absorbers in axle pairs. Backed by Bilstein's reputation as the pioneer of monotube gas-pressure shock absorber technology and a trusted OE supplier to brands including Mercedes-Benz, BMW, Porsche, and others.
