Koni 8245 1417R Special Active Front Passenger Side Shock Absorber

The Koni 8245 1417R Special Active shock absorber represents the latest generation of premium suspension technology, delivering superior handling performance without compromising ride comfort. This twin-tube, low-pressure gas shock is engineered for front passenger side installation and features Koni's advanced Frequency Selective Damping (FSD) technology.

Frequency Selective Damping Technology:

At the core of the Special Active design is Koni's patented FSD valve system, which automatically adjusts damping characteristics based on suspension input frequency. The internal hydraulic valve responds intelligently to road conditions—providing firmer damping during low-frequency inputs like braking, acceleration, and cornering to control body motion, while simultaneously allowing high-frequency inputs from rough pavement to pass through with reduced resistance for improved comfort. This automatic adaptation happens mechanically without the need for electronic sensors, cables, or control modules.

Key Features:

• Patented Frequency Selective Damping technology proven on over 10 million factory-equipped vehicles
• Twin-tube hydraulic design with low-pressure gas charge
• Automatically adjusts to changing road conditions and driving styles
• Delivers performance handling on smooth surfaces and comfort on rough roads
• No electronic components required—purely mechanical operation
• Improves safety through enhanced road holding and tire contact
• Developed from OE-proven suspension engineering used by major vehicle manufacturers

The Special Active series represents Koni's commitment to providing technology that rivals expensive electronic damping systems while maintaining the reliability and simplicity of purely mechanical operation. Whether navigating spirited driving on smooth pavement or absorbing expansion joints and uneven surfaces during daily commutes, this shock absorber delivers consistent, predictable performance.
