KYB SRX4547 Suspension Strut and Coil Spring Assembly - Front

KYB Truck-Plus Leveling Assembly for Silverado and Sierra

The KYB Truck-Plus Leveling Assembly is a front suspension strut and coil spring assembly for truck owners who need to restore ride height and front-end control. Part number SRX4547 is built for specific applications, including 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 models without electronic suspension, plus 2019 Silverado 1500 LD and Sierra 1500 Limited front applications with the listed exclusions.

Truck-Plus Product Line Details

KYB’s Truck-Plus Leveling Assembly line is engineered as a corner-specific replacement, rather than a universal fitment approach. That matters because the front strut assembly carries vehicle weight, sets ride height, serves as a steering pivot, and contributes to stability and electronic crash-avoidance system performance. SRX4547 follows that application-specific design for the Chevrolet Silverado 1500 and GMC Sierra 1500 platform.

Detailed Description

KYB SRX4547 is a Truck-Plus Leveling Assembly designed for front suspension service on select Chevrolet Silverado 1500 and GMC Sierra 1500 trucks. It is intended for drivers who need a direct-fit strut and coil spring assembly that addresses front ride height while maintaining the vehicle’s original suspension geometry for the listed applications. This part number is built for the front position and is not listed for electronic suspension-equipped models.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Front-end sag or uneven ride height
• Worn strut assembly performance on the front suspension
• Reduced steering response from a fatigued front strut
• Excessive nose-down stance on leveled truck applications
• Stability concerns tied to aging suspension components

Installation Notes and Tips

Install SRX4547 only on the listed front applications: 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 without electronic suspension, or 2019 Silverado 1500 LD and Sierra 1500 Limited with the stated exclusions. Verify the vehicle’s suspension equipment before ordering, since electronic suspension applications are excluded. Because this is a complete strut and coil spring assembly, it is used as a direct front suspension replacement rather than a component rebuild.

Quality Assurance

KYB manufactures application-specific replacement suspension components with corner-specific part numbers to help restore designed vehicle performance. SRX4547 follows that approach for the listed Silverado and Sierra front applications, supporting consistent fitment and suspension function.
