Product Details

The KYB Excel-G brand line is built for drivers who want the truck to respond the way it was originally engineered to. KYB manufactures Excel-G on the same OE assembly lines used for original equipment production, using OE-quality components and application-specific valving. For Ford F-250 Super Duty and Ford F-350 Super Duty rear suspension service, part number 345070 is designed to restore control, stability, stopping consistency, lane-change response, and handling without changing the vehicle’s intended character.

This part cross-references Monroe Shocks & Struts 911267 for the same application.

What It Helps Address

• Excessive rear bounce or oscillation after bumps
• Reduced stability during towing, hauling, or uneven-road driving
• Slow body control during lane changes and cornering
• Uneven tire contact caused by worn damping performance
• Loss of original ride control on high-mileage Ford Super Duty trucks
