Fits select 2006-2013 Lexus IS250 and IS350 models (Base and C trims).

The KYB Gas-a-just (551132) is a high-pressure monotube shock absorber designed to restore your vehicle's original handling and control. Unlike standard twin-tube shocks, the Gas-a-just design eliminates performance fade by separating the fluid and gas chambers. It features a hydraulic piston and valve area for immediate responsiveness, combined with a second high-pressure nitrogen gas chamber containing a floating piston. This configuration ensures a comfortable ride during normal cruising while providing instant damping performance on demand.

  • Monotube design provides increased damping performance and faster response times over OE twin-tube units
  • Separate floating piston prevents aeration and foaming to maintain consistent control
  • Essential for maintaining the calibration and performance of factory electronic safety systems
  • Sealed high-pressure nitrogen gas charge reduces fluid cavitation
  • Direct replacement for the factory rear shock absorber
  • Manufacturer Part Number: 551132
