Infiniti QX4 2003, Gas-a-Just™ Rear Monotube Shock Absorber by KYB®. Quantity: 1 per Pack. 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 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.

A lot of us use our vehicle for more than just daily commuting. Many of us pull trailers or transport heavy items, so we need more ride control and performance than usual. KYB has a sound solution for all of these driving needs – the Gas-a-Just monotube shock absorber! The name of the shock stands for gas automatic adjust. The Gas-a-Just will outperform the average twin-tube design; it never experiences shock fade and has a unique ability to automatically add performance when it's needed. The Gas-a-Just has two possible purposes. For those vehicles that are already equipped with a high performance monotube design, the Gas-a-Just will serve as a direct replacement to restore the vehicle's originally designed performance. But the Gas-a-Just can also be a great performance upgrade for the vehicles that are equipped with standard twin-tube shocks.
The Gas-a-Just features a larger single working cylinder, so the hydraulic fluid doesn't have to travel far. It's all kept in the upper cylinder so the valving can respond faster. There is also a Nitrogen gas high pressure chamber in the lower section (it is separated from the fluid area by a floating piston and seal). On light vehicle movement, the gas pressure cushions the ride, but when you need performance and there's more aggressive movement, the floating piston is pushed further into the gas chamber which increases gas pressure quickly and provides additional damping force. The Gas-a-Just is a great choice when you want something more than the original design. Whether you just want more responsive handling or perhaps you carry heavier loads than usually, or tow a trailer, the Gas-Just provides more stability and less body roll. So, install a pair of Gas-a-Just Shocks and Struts and experience a firmer ride and additional control.
