The KYB rear replacement shock for Jeep Grand Cherokee (1999–2004) is offered to restore original ride control and stability. KYB's Gas-a-just monotube design, referenced in the product notes, uses an air-free hydraulic piston plus a high-pressure nitrogen chamber with a floating piston to resist aeration and prevent fade, providing comfortable everyday ride qualities and instant performance when demanded.
