KYB Shocks & Struts Gas-A-Just Rear INFINITI QX4 (2WD) 2001-03 INFINITI QX4 (4WD) 1999-03 NISSAN Pat

The KYB Gas-A-Just monotube shock absorber uses a unique design with two separate working chambers to give you the best of both worlds. One chamber has an air-free hydraulic piston and valve area that responds instantly to your driving needs, giving you better control. The second chamber holds high-pressure nitrogen gas with a floating piston, which makes for a comfortable ride during normal driving but adds performance when you need it, like during hard braking or cornering. This means you get a shock that never experiences fade due to aeration and helps keep your vehicle's electronic safety systems working as the manufacturer intended.

This shock absorber is a well-built monotube design, which is known for being more responsive than traditional twin-tube shocks. It's designed to automatically adjust to your driving conditions, providing a comfortable ride when you're cruising and improved control when you push the vehicle a little harder. This makes it a solid option for keeping your 1999-2004 Nissan Pathfinder or 1999-2003 Infiniti QX4 handling reliably.
