Detailed Description

On the Toyota Land Cruiser, this rear shock absorber helps return consistent damping, body control, and road feel after the original unit has worn. The design uses KYB’s OE manufacturing process and quality components to support predictable performance in everyday driving and load-carrying conditions.
