The KYB Gas-A-Just KG5507 is a high-performance rear monotube shock absorber designed to provide superior damping control compared to traditional twin-tube designs. Engineered for vehicles that require higher levels of stability, this shock instantly and automatically adjusts to road conditions, ensuring consistent tire-to-road contact. Its monotube construction utilizes a high-pressure nitrogen gas charge and a floating piston to completely separate the hydraulic fluid from the gas, preventing the aeration and performance fade common in standard shocks.

• Monotube design delivers up to 30% more damping performance than standard twin-tube shocks.
• High-pressure nitrogen gas charge provides instant response and prevents fluid foaming.
• Two-chamber design features a floating piston to maintain a comfortable ride during normal driving and added control on demand.
• Restores handling characteristics necessary for the proper operation of modern Electronic Safety Systems.
• Direct-fit application replaces worn OE rear shocks with no modification required.
• Manufacturer Part Number: KG5507.
