The Air Lift Performance Rear Air Suspension Kit is designed for Infiniti Q50 and Q60 applications, providing adjustable ride height with performance-oriented handling and damping. The system combines progressive-rate double-bellows air springs with high-performance monotube shocks for a balance of aggressive styling, ride quality, and suspension control.

With up to a 4-inch (101.6mm) drop from stock ride height and 32 levels of damping adjustment, the rear suspension can be fine-tuned for different driving conditions and preferences. Threaded adjustable lower mounts provide additional setup flexibility, while vehicle-specific air spring brackets ensure proper installation. :contentReference[oaicite:0]{index=0}
