KYB For Chevy Silverado 1500 HD 2001-2006 Shocks & Struts Gas-A-Just Rear | KG54342

The KYB Gas-a-just monotube truck shock absorber has additional performance advantages over the 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. High gas pressure design provides instant, extra control. Factory Sealed - Brand new in box
