KYB New Shock Absorber
(Shock Absorber - New KYB Gas-a-just Series)
Low Inventory – Order Soon.

This is a New KYB Shock Absorber (Note: New KYB Gas-a-just Series). SKU number U8-13749-A4
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.
