Product Details

KYB MonoMax is the brand’s heavy-duty shock line for trucks that work harder than a typical daily driver. The MonoMax series focuses on stability, fade resistance, and durability, making it a practical upgrade for a Ford F-150 used for hauling, towing, off-road driving, or carrying heavier loads. Part number 5650006 is a rear suspension shock absorber for select 2009-2025 Ford F-150 applications, including models with standard or off-road packages and specific exclusions for electronic suspension and heavy duty payload package configurations.
