Description

Restore the designed ride control and handling of your heavy-duty Super Duty with the KYB Excel-G Gas Shock (MPN 3440177). This is the KYB-recommended OEM replacement rear shock absorber, and it drops in as a direct-fit replacement for the 2017-2022 Ford F-450 Super Duty and 2017-2022 Ford F-550 Super Duty — see the "Vehicles it fits" section for engine-level fitment. Excel-G is a nitrogen gas-charged, twin-tube design made on the same KYB OE assembly lines with the same OE-quality components, calibrated to restore original designed performance rather than change it — the classification KYB calls OEA (Original Equipment for the Aftermarket).

Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
Vehicle-specific damping valves: hand assembled in-house to manage tire contact, steering response and body movement.
Supports electronic safety systems: helps keep the suspension operating as the vehicle manufacturer intended so those systems perform as designed.

Designed to help restore stability, stopping, lane-change responsiveness and handling on heavy-duty trucks and commercial vehicles. Replacing rear shocks as a matched pair is recommended for balanced ride control.
