KYB Shocks & Struts Gas-A-Just Rear INFINITI QX4 (4WD) 1997-99 NISSAN Pathfinder (2WD) 1996-99 NISSA

This product is a single KYB Gas-A-Just rear shock absorber. It's designed to help your 1996-1999 2WD Nissan Pathfinder or 1997-1999 4WD Infiniti QX4 maintain its intended ride and handling characteristics. Modern vehicles rely on a properly functioning suspension to keep electronic safety systems, like stability control and ABS, working as the manufacturer intended, and this shock helps ensure that happens.

The Gas-a-just uses a monotube design, which means it has separate chambers for hydraulic fluid and high-pressure nitrogen gas. This setup allows the shock to automatically adjust its damping force based on driving conditions. During normal cruising, it offers a comfortable ride, but when you encounter rougher roads or need more control during cornering, it instantly stiffens up to provide better responsiveness. This design also prevents the aeration that can cause traditional twin-tube shocks to fade under heavy use.
