Koni 86-1942 Special/Classic 86 Series Internally Adjustable Non-Gas Strut Insert

The Koni 86-1942 is a Special/Classic 86 Series strut insert designed for drivers seeking improved handling and road safety without sacrificing everyday driveability. This is a red-painted, twin-tube, non-gas-charged strut cartridge with internally adjustable rebound damping — purpose-built for classic and performance street applications.

Each insert is custom-engineered for its specific application and manufactured to Koni's exacting tolerances. Every damper is 100% dyno-tested at the end of the production line to ensure consistent, optimum performance right out of the box.

Rebound Adjustment: Unlike Koni's Sport range, which is adjustable on the vehicle, the Special/Classic 86 Series requires removal from the car to change damping settings. Rebound force is adjusted by compressing and rotating the piston rod — giving you precise, repeatable control over ride quality and handling balance.

Key Features:

• Twin-tube, non-gas design — smooth, progressive damping for street and classic car use
• Internally adjustable rebound — tunable off-vehicle by compressing and twisting the piston rod
• Red finish — iconic Koni Special Series identifier
• 100% dyno-tested — every unit verified at the factory before shipment
• Broad application coverage — engineered specifically for individual vehicle models
• Lifetime warranty — backed by Koni's industry-leading guarantee

Sold individually. A complete set requires four units. Koni Special/Classic strut inserts are the ideal upgrade for enthusiasts restoring or improving classic vehicles who want genuine adjustability and long-term reliability from a brand with over 90 years of damper manufacturing heritage.
