Koni 86-1919 Special D Red Strut Insert Twin-Tube Internally Adjustable Non-Gas

The Koni 86-1919 is a Special D (Classic 86 Series) strut insert — a red-painted, internally adjustable, twin-tube non-gas charged strut cartridge designed to upgrade handling and ride quality over stock dampers. Built to drop into the OEM strut housing, this insert delivers improved road holding and a higher level of driving confidence at an accessible price point.

Rebound damping is fully adjustable, though adjustment requires removing the insert from the vehicle first. Damping force is changed by compressing and twisting the piston rod, allowing the driver to tune the suspension to their preferred driving style or road surface conditions.

Key Features:

• Twin-tube, non-gas charged hydraulic design for smooth, consistent damping
• Internally adjustable rebound damping — off-vehicle adjustment via piston rod compression and rotation
• Red finish with classic Koni wing logo
• Strut insert design — installs into existing OEM strut housing, no new strut assembly required
• Stock ride height maintained
• Broad application coverage across a wide range of vehicles
• Koni Lifetime Warranty included

Sold individually. A complete set requires the appropriate quantity for your application. Koni's 86 Series inserts have been a benchmark in the suspension industry, combining proven hydraulic technology with real-world adjustability for drivers who want more from their ride without sacrificing comfort.
