The KYB Gas-a-just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The Gas-a-just is available as an OE monotube replacement and as an OE twin-tube performance upgrade. The KYB Gas-a-just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.This Part Fits: Year Make Model Submodel 1999-2003 Infiniti QX4 Base 1999-2004 Nissan Pathfinder LE 1999-2004 Nissan Pathfinder SE 1999-2001 Nissan Pathfinder XE
