Features

• Bilstein B6 Performance product line - a meaningful performance upgrade over OE stock dampers delivering sharper handling response, improved lane stability, and better control while retaining daily-driver comfort at factory ride height
• Monotube gas pressure design - 36mm piston in a single-tube construction provides superior heat dissipation and consistent fade-free damping performance; maintains full damping power even under repeated compression cycles
• Velocity-sensitive digressive piston - instantly reacts to changing road conditions, providing a smooth ride on regular surfaces while delivering controlled damping over rough pavement, bumps, and emergency maneuvers
• Application-specific valve calibration - individually tuned for the Smart Fortwo 453's rear suspension geometry, spring rates, and weight distribution as a rear-engine RWD microcar
• Works with factory OE springs - no spring replacement or additional hardware required for installation

Product Description

The Bilstein 24-264426 is a B6 Performance rear monotube shock absorber designed as a direct performance upgrade for the 2016-2018 Smart Fortwo (453 series) in RWD configuration across all trims. It replaces the factory rear damper with Bilstein's 36mm monotube gas pressure unit featuring application-specific valve calibration developed for the Smart Fortwo's unique rear-engine, rear-wheel-drive rear suspension geometry - delivering sharper handling response and improved lane stability without altering ride height or requiring spring changes.

The Smart Fortwo 453's compact, rear-engine layout places particular demands on rear damper calibration - the B6's velocity-sensitive digressive piston is tuned specifically for the Fortwo's weight distribution and rear suspension travel characteristics, maintaining consistent damping through the full range of the microcar's suspension movement. The yellow paint finish provides corrosion resistance, and stem/eye mounting mates directly to the factory Fortwo mounting points. For a complete B6 Performance front-and-rear upgrade, pair this shock with the companion front strut Bilstein 22-248268. Sold individually - order two for a complete rear pair.
