KYB SRX4545 Suspension Strut and Coil Spring Assembly - Front

KYB Truck-Plus Leveling Assembly for Front Suspension

The KYB Truck-Plus Leveling Assembly SRX4545 is a front suspension strut and coil spring assembly for select Chevrolet and GMC trucks and SUVs. It is built to raise the front ride height while restoring the handling, steering response, and stability expected from the original suspension design.

For applications such as the Chevrolet Tahoe, GMC Yukon, GMC Yukon XL, Chevrolet Silverado 1500, and GMC Sierra 1500, this assembly is engineered as a corner-specific replacement rather than a one-size-fits-all unit. The KYB Truck-Plus Leveling Assembly line focuses on restoring vehicle-specific performance where front ride height and suspension geometry matter.

• Part number SRX4545 for select Chevrolet and GMC front suspension fitments
• Compressed length: 14.17 in.
• Extended length: 17.52 in.
• Stroke length: 3.35 in.
• Boot included
• Corner-specific design for vehicle-specific suspension tuning

Detailed Description

The KYB Truck-Plus Leveling Assembly SRX4545 is designed for drivers who need a front-end leveling solution without compromising the suspension’s role in ride control and steering precision. A strut assembly carries vehicle weight, helps establish ride height, serves as a steering pivot, and contributes to stability and electronic crash-avoidance system performance. This makes correct application and geometry especially important on trucks and SUVs.

Compatible With 2015-2020 Chevrolet Tahoe, front, except electronic suspension and without police package; 2015-2020 GMC Yukon, front, except electronic suspension and without police package; 2015-2020 GMC Yukon XL, front, except electronic suspension; 2014-2018 Chevrolet Silverado 1500, front, without electronic suspension; and 2014-2018 GMC Sierra 1500, front, without electronic suspension. 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
• Worn strut assembly performance on leveling applications
• Reduced steering response from tired suspension components
• Excessive body motion or instability over uneven roads
• Suspension replacement needs on select Tahoe, Yukon, Silverado 1500, and Sierra 1500 models

Installation Notes and Tips

Verify electronic suspension, police package, and model-year fitment before installation. This assembly is for front position applications only and should be matched to the exact vehicle configuration listed above. Because strut assemblies affect ride height and steering geometry, professional installation and a post-installation alignment are recommended.

Quality Assurance

KYB designs the Truck-Plus Leveling Assembly with corner-specific part numbers to better match the intended vehicle application. The SRX4545 is built as a direct-fit suspension replacement for the listed Chevrolet and GMC front suspension applications.
