Detailed Description

Built as an all-in-one front suspension strut and coil spring assembly, the Rancho RS551830 simplifies replacement on 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 models, plus 2019 Chevrolet Silverado 1500 LD and 2019 GMC Sierra 1500 Limited front applications. It is engineered to restore OE ride height while delivering more controlled handling for daily driving and light off-road use. This part number, RS551830, is a direct-fit suspension service option for front-end repair on Silverado 1500 and Sierra 1500 trucks.

This part cross-references Monroe Shocks & Struts (e.g., 153026, 239112) for the same application.

What It Helps Fix

• Front-end sag or reduced ride height
• Loose or unsettled handling over bumps
• Worn strut assembly noise and ride degradation
• Reduced control during braking and cornering
• Time-consuming assembly of separate suspension components

Installation Notes and Tips

Fits 2014-2018 Chevrolet Silverado 1500, front. Fits 2014-2018 GMC Sierra 1500, front. Fits 2019 Chevrolet Silverado 1500 LD, front. Fits 2019 GMC Sierra 1500 Limited, front. Verify front suspension configuration and compare compressed and extended lengths before installation. Because this is a loaded assembly, it is suited to complete front strut replacement rather than component-level rebuilds.
