Koni 8045 1337 Special Active Rear Shock Absorber

The Koni 8045 1337 Special Active is a premium rear shock absorber featuring advanced Frequency Selective Damping (FSD) technology that automatically adapts to changing road conditions without any manual adjustment. This next-generation shock absorber delivers superior handling performance while maintaining exceptional ride comfort, making it ideal for drivers who refuse to compromise between sportiness and daily drivability.

Key Features:

• Patented Frequency Selective Damping (FSD) technology automatically adjusts damping forces in real-time based on road input frequency
• Twin-tube hydraulic design with low-pressure gas charging for optimal balance of comfort and control
• Non-adjustable, set-it-and-forget-it operation—no knobs or manual tuning required
• Reduces body roll, brake dive, and pitch under acceleration without increasing harshness
• Provides soft damping for small bumps and rough pavement, firm damping for cornering and large impacts
• Technology proven on over 10 million factory-equipped vehicles worldwide
• Manufactured to strict tolerances using high-quality materials for long-lasting durability

Unlike conventional shock absorbers that compromise between comfort and handling, the Koni Special Active uses purely mechanical valve control to intelligently respond to different driving conditions. High-frequency inputs like expansion joints and small road imperfections are absorbed smoothly for comfort, while low-frequency motions from cornering and larger bumps are controlled firmly for stability and safety. The result is a refined driving experience that rivals expensive electronic suspension systems at a fraction of the cost.
