Rancho RS551784 Suspension Strut and Coil Spring Assembly - Front

Rancho RS5000X Loaded Front Strut Assembly

The Rancho RS551784 is a front suspension strut and coil spring assembly built for late-model trucks and SUVs that need factory ride height restoration with more controlled handling. It combines the strut, spring, and related components into one assembly to simplify service on Chevrolet Tahoe, Silverado 1500, and GMC Yukon applications.

• Loaded front strut assembly for suspension service and ride-height restoration
• Cross Tuned technology for balanced on-road and off-road response
• Gas charged design for consistent damping performance
• Performance-grade construction for daily driving and demanding use
• Mounting hardware included for a more complete installation
• Fits front applications on 2007-2020 Chevrolet Tahoe, 2007-2020 GMC Yukon, and related GM trucks and SUVs

Fitment and Application Details

Compatible with front suspension applications on 2007-2020 Chevrolet Tahoe, 2007-2020 GMC Yukon, 2015-2020 GMC Yukon XL, 2019 Chevrolet Silverado 1500 LD, 2019 GMC Sierra 1500 Limited, 2007-2018 Chevrolet Silverado 1500, 2007-2018 GMC Sierra 1500, 2007-2014 Chevrolet Suburban 1500, and 2007-2014 GMC Yukon XL 1500. The Rancho RS551784 is engineered as a direct front replacement for these vehicles and is built to restore factory ride height while improving control.

This part cross-references Monroe Shocks & Struts (e.g., 139104, 139105) for the same application.

What It Helps Address

• Front-end sag from worn original struts and springs
• Loose or inconsistent ride control over bumps and pavement transitions
• Reduced stability during braking, cornering, or towing-related load changes
• Noise and harshness caused by aging suspension components
• Time-consuming assembly work when replacing separate strut parts

Installation Notes and Tips

RS551784 is a front suspension strut and coil spring assembly with gas-charged construction and a 3.81-inch travel length. Its compressed length is 13.91 inches, extended length is 17.72 inches, and body length is 11.29 inches. Verify front suspension configuration and match the vehicle application before installation. Because this is a complete assembly, it can reduce the need to transfer individual spring and strut components during service.

Quality Assurance

Rancho states that the RS5000X Loaded assembly is ride tested on and off road and engineered to strict durability requirements. The RS551784 is part of Rancho’s performance suspension lineup and is built for consistent service in truck and SUV front suspension applications.
