Product Details

KYB Steering Stabilizers are part of the KYB Steering Stabilizer line, focused on damping unwanted steering movement before it reaches the steering wheel. SS15489 is designed for front-end applications where vibration control and tire tracking matter, especially on Ford F-250 Super Duty, Ford F-350 Super Duty, and Ford Excursion models used for towing, hauling, or off-road driving. This part cross-references Monroe Shocks & Struts SC2961 for the same application.

Common Issues This Part Helps Address

• Steering wheel shimmy at highway speeds
• Front-end vibration transmitted through the steering system
• Reduced steering control on uneven roads or trails
• Premature tire wear caused by excessive shimmy
• Loose or unsettled steering feel on Ford Super Duty trucks

Installation Notes and Tips

Verify mount style, compressed length, and extended length before installation. SS15489 uses an S1 lower mount and E1 upper mount, so matching the existing steering stabilizer hardware and bracket configuration is important for proper fitment. Inspect related steering components, tires, and front-end alignment during replacement to confirm the source of vibration has been addressed.

Quality Assurance

KYB designs steering stabilizers to control vibration at the source and support consistent steering response in demanding truck applications. SS15489 is engineered as an OE replacement for the listed Ford fitments and follows KYB’s application-specific approach to steering control.
