Description
Part #: KG4505
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.
MIA's Description
Each unit features a monotube design that provides responsive road feedback. The shock includes necessary washers, bushings, and nuts, while requiring the reuse of factory shock mounting bolts for installation.
