Koni 8705 1330 FSD Red Series Frequency Selective Damping Full Strut

The Koni 8705 1330 is a premium FSD (Frequency Selective Damping) full strut from Koni's 8705 Red Series, featuring active ride control technology engineered to eliminate the traditional compromise between ride comfort and handling performance. Finished in Koni's signature red paint, this full strut delivers an automatically adaptive damping experience without any electronic components.

Koni's patented Frequency Selective Damping (FSD) technology uses a specialized internal valve that automatically adjusts damping force based on road input frequency. At low frequencies — such as body roll, cornering, and braking — the strut generates firm damping forces for maximum control. At high frequencies — such as expansion joints, rough pavement, and road vibrations — it softens to absorb impacts and deliver a smooth, comfortable ride.

Key Features:

• Frequency Selective Damping (FSD) — automatically adapts to road conditions with no driver input required
• Twin-tube internal design — proven construction for durability and consistent performance
• Red-painted full strut — complete, ready-to-install unit in Koni's iconic red finish
• Stock ride height — direct OEM replacement fitment
• Non-electronic active damping — delivers performance of an electronic system in a fully mechanical, integrated package
• Firm when it counts — controls body roll, bounce, and brake dive under dynamic driving conditions
• Smooth over rough roads — reduces vibration from expansion joints and uneven surfaces
• Sold individually

The Koni 8705 1330 FSD strut is an ideal upgrade for drivers seeking improved suspension performance and ride quality. Its patented technology has been proven across more than 10 million factory-equipped vehicles worldwide, making it one of the most trusted names in performance damping.
