KYB SRM4545 Suspension Strut and Coil Spring Assembly - Front

KYB Truck-Plus Front Strut Assembly

The KYB Truck-Plus Performance Assembly is a front suspension strut and coil spring assembly built for truck and SUV applications that need precise ride height control, stable handling, and consistent steering response. This SRM4545 assembly is engineered for specific vehicle fitment rather than a one-size-fits-all design.

Compatible with 2014-2018 Chevrolet Silverado 1500 front and 2015-2020 Chevrolet Tahoe front, as well as 2014-2018 GMC Sierra 1500 front, 2015-2020 GMC Yukon front, and 2015-2020 GMC Yukon XL front, this part number SRM4545 is a direct-fit suspension service option for selected vehicles without electronic suspension.

Product Details

KYB designs the Truck-Plus line for truck applications where the strut assembly affects vehicle weight support, ride height, steering pivot action, stability, and electronic crash avoidance system performance. The SRM4545 is built for the front suspension on select Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Sierra 1500, GMC Yukon, and GMC Yukon XL models, with fitment exclusions for electronic suspension and, on certain applications, police package equipment. If you are replacing a worn front strut assembly on a 2015-2020 GMC Yukon front suspension or a 2014-2018 Chevrolet Silverado 1500 front suspension, this KYB assembly provides a vehicle-specific replacement path.

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

What It Helps Address

• Front-end sag or uneven ride height
• Noisy or worn strut assembly operation
• Excessive body movement over bumps and dips
• Loose or inconsistent steering feel from a worn front strut
• Ride quality decline on high-mileage truck and SUV suspensions

Installation Notes

Install only on the listed front applications and verify that the vehicle does not have electronic suspension where excluded. Confirm model year, trim, and package details before ordering, especially for Tahoe and Yukon applications with police package or electronic suspension differences. Because this is a complete strut and coil spring assembly, it is suited for replacing the front suspension unit as a matched assembly rather than rebuilding individual components.

Quality Assurance

KYB builds the Truck-Plus line with application-specific engineering for truck suspension demands, avoiding generic multi-vehicle fitment. The SRM4545 is designed around the listed dimensions and vehicle coverage to support consistent front suspension performance on the specified Chevrolet and GMC platforms.
