KYB Suspension Shock Absorber P/N:KG4613A
Get controlled, comfortable damping from the KYB shock absorber Gas-a-just KG54317, a high-pressure monotube gas unit that installs as a rear shock on the 1996-2002 Toyota 4Runner. Its components and valving were designed specifically for the Toyota 4Runner, making it a direct-fit rear replacement for the listed applications.
The Gas-a-just is offered as an OE monotube replacement to help restore your vehicle's original capabilities. It uses two separate working chambers: an air-free hydraulic piston and valve area for responsiveness and control, and a high-pressure nitrogen gas area with a floating piston for a comfortable ride during normal driving with added performance on demand.
Shocks work as a pair — replace both rear units together for balanced, even damping.
