Koni 30-1090 Special Series Red 4-Position Adjustable Monotube Gas Shock Absorber

The Koni 30-1090 Special Series shock absorber is engineered for drivers seeking improved handling performance and enhanced road safety without sacrificing everyday drivability. Built as a monotube, high-pressure gas unit, this shock delivers consistent damping performance and superior heat dissipation compared to twin-tube designs — making it an ideal upgrade over worn factory shocks.

Finished in Koni's signature red exterior, the Special Series (also known as the "30 Series") features 4-position rebound adjustability, allowing fine-tuning of the damping characteristics to suit your driving style and road conditions. Adjustment is performed off the vehicle by compressing and twisting the piston rod — a straightforward process that gives you meaningful control over ride and handling behavior.

Key Features:

• Monotube, high-pressure gas design for improved performance and fade resistance
• 4-position rebound adjustment performed off the vehicle by compressing and rotating the piston rod
• Iconic red finish — Koni's hallmark Special Series identifier
• Broad vehicle application coverage — custom valved for individual makes and models
• Lifetime warranty — backed by Koni's industry-leading guarantee
• Sold individually — a complete rear installation requires 4 shocks

The Koni Special Series is the go-to choice for enthusiasts and everyday drivers alike who want a proven, adjustable performance shock with a legacy of quality engineering. Each unit is custom-designed and manufactured for the specific vehicle model, ensuring a precise fit and optimized damping response straight out of the box.
