Koni 26-1089 Special D Red 3-Position Adjustable Mono-Tube High Pressure Gas Shock Absorber

The Koni 26-1089 Special D (Red) is a 3-position adjustable, mono-tube high-pressure gas shock absorber engineered to deliver a meaningful upgrade in ride quality, road holding, and overall driving safety. Part of Koni's iconic Special Series — the original Koni damper line — this shock is custom-designed and individually tuned for specific vehicle models, ensuring precise damping characteristics rather than a one-size-fits-all approach.

The 26-1089 uses a mono-tube high-pressure gas construction, which provides superior heat dissipation and more consistent damping performance compared to traditional twin-tube designs. The result is a shock absorber that delivers sharper handling response and improved stability under demanding driving conditions.

Rebound Adjustment: The Special Series features off-vehicle rebound adjustment. By removing the shock, compressing, and rotating the piston rod, drivers can select from three distinct damping settings — from a softer, comfort-oriented tune to a firmer, performance-focused setup — allowing the suspension to be tailored to personal driving preferences.

Key Features:

• 3-Position off-vehicle rebound adjustment via piston rod compression and rotation
• Mono-tube high-pressure gas design for consistent, fade-free damping performance
• Custom-tuned per vehicle model for optimized handling and safety
• Signature red finish with classic Koni wing logo
• Broad application coverage across a wide range of passenger vehicles
• Lifetime warranty to the original purchaser
