Ksport CSU090-ASO Airtech Air Struts Only Air Suspension Kit Adjustable Damping - with 36-Way

The Ksport CSU090-ASO Airtech Air Struts Only kit delivers premium air suspension performance with near-infinite ride height adjustability — ideal for enthusiasts who want to integrate high-quality Ksport air struts into an existing air management setup or replace worn struts without purchasing a full system.

These air struts are built around high-pressure air bags engineered and matched specifically to the vehicle application. Depending on OEM suspension configuration, sleeve-type or double-bellows air bags are available. Air pressure directly controls ride stiffness — higher PSI yields a firmer feel, while lower PSI softens the ride for daily comfort.

The monotube shock absorbers share the same proven design found in Ksport's best-selling Kontrol Pro coilover kits, featuring internal valving tuned specifically to accommodate air pressure changes. Steel shock bodies are zinc electroplated for corrosion resistance, while spring perches, collars, and lower mounts are machined from 6061 billet aluminum for lightweight durability.

Key Features:

• 36-Way Adjustable Damping — dial in compression and rebound simultaneously using the included damping knob; turn counterclockwise for a softer setting or clockwise for increased stiffness
• Adjustable Lower Mounts — fine-tune ride height at virtually any PSI without sacrificing suspension travel, a common limitation in standard coilover systems
• Wide Height Adjustability — 0 to 120/200mm of lowering range depending on vehicle application
• High-Pressure Air Bags — engineered to withstand daily driving stress and track use; sleeve and double-bellows configurations available based on OEM suspension type
• Monotube Shock Design — separates oil and gas within the cylinder for faster, more even heat dissipation and reduced aeration/cavitation compared to twin-tube designs
• Zinc Electroplated Shock Bodies — resists rust and protects against road contaminants and harsh environments
• 6061 Billet Aluminum Components — lightweight, strong, and rust-resistant mounts, collars, and perches
• Bolt-On Installation — no modifications to OEM shock absorbers or OEM top mounts required; note that vehicle may require modification for air line routing
• Compatible with Most Air Management Systems — works with a wide range of aftermarket air management setups on the market
• 12-Month Limited Warranty — covers manufacturer defects from original date of purchase
