KYB SRG4456 Suspension Strut and Coil Spring Assembly - Front

KYB Truck-Plus Front Strut Assembly

The KYB Truck-Plus Performance Assembly SRG4456 is a front suspension strut and coil spring assembly built for truck and SUV applications that need precise ride height control and stable handling. It is engineered around the demands of the suspension system, where the strut assembly carries vehicle weight, sets ride height, serves as a steering pivot, and influences stability systems.

• Front suspension strut and coil spring assembly
• Compressed length: 16.36 in.
• Extended length: 20.69 in.
• Stroke length: 4.33 in.
• Boot included
• Application-specific design for the listed vehicles

Truck-Plus Performance Assembly Details

KYB’s Truck-Plus Performance Assembly line focuses on direct-fit replacement parts for truck and SUV suspension service, with attention to the exact geometry required by the vehicle. Part number SRG4456 is built for the front suspension on 2014-2017 Ford Expedition, 2015-2017 Lincoln Navigator, 2014 Ford F-150 without the Heavy Duty Payload Package, and 2014 Lincoln Navigator without self-leveling suspension. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Symptoms

• Front-end ride height that has dropped or become uneven

• Loose or unstable steering feel at the front suspension
• Noisy or worn strut assembly during suspension travel
• Handling changes after suspension wear on Expedition, Navigator, or F-150 models

Installation Notes

Verify the vehicle’s suspension equipment before ordering, especially Electronic and Load Leveling Suspension or self-leveling configurations. Confirm front application, compare compressed and extended length measurements, and inspect related suspension components during replacement. Because this is a complete strut and coil spring assembly, it is suited to replacing the front unit as an assembly rather than rebuilding individual components.

Quality Assurance

KYB designs the Truck-Plus line with vehicle-specific suspension geometry in mind, rather than a one-size-fits-all approach. The SRG4456 is built to match the listed fitments and the functional demands of the front suspension on Ford Expedition, Lincoln Navigator, and Ford F-150 applications.
