KYB 565011 Shock Absorber - Rear

KYB MonoMax Rear Shock for Ford Ranger and Jeep

The KYB MonoMax 565011 is a heavy-duty rear suspension shock absorber built for trucks and SUVs that work harder than a standard shock can handle. It is a monotube design with a large bore for added control, stable damping, and consistent response under load.

For Ford Ranger rear shock replacement and select Jeep rear applications, this KYB MonoMax shock is aimed at towing, hauling, and off-road use where suspension control matters. The 565011 also supports vehicles with electronic safety systems such as ESC and ABS.
