Monroe Quick-Strut 139104 Suspension Strut and Coil Spring Assembly

Our review of the Monroe Quick-Strut 139104 finds it best suited for owners of full-size Chevrolet and GMC SUVs who need a direct, reliable replacement for a worn front strut assembly. The single biggest reason to buy is convenience: this is a fully assembled unit that eliminates the need for a spring compressor and delivers an application-specific coil spring and mount designed to restore original ride height. For anyone who wants a like-for-like repair with straightforward installation and OE-style fit, this Quick-Strut is a practical choice.

Key Features

• Fully assembled unit: Includes strut, coil spring and upper mount so installation is quicker, safer and does not require a spring compressor.
• Vehicle-specific design: The coil spring and mount are tailored to the application to preserve handling and ride characteristics unique to the vehicle.
• Restores ride height: Springs are calibrated to meet the original equipment design and support the vehicle's weight to return proper ride height.
• OE-style quality: Preassembled parts follow OE design for seamless fit, form and function during a straight swap.
• Durable construction: Built from quality steel with superior tube and weld design to provide structural integrity and long service life.
• Rust protection: Protective coating and salt spray trial reduce corrosion and improve long-term resistance to the elements.

Who It's For

The Monroe Quick-Strut 139104 is aimed at DIY mechanics and professional installers working on compatible Chevrolet Suburban, Tahoe, Avalanche and GMC Yukon models who want a ready-to-install replacement that restores ride height and steering feel. It is especially useful for those replacing damaged or worn front struts and who value ease of installation and OE-style performance.

Those who should look elsewhere include owners needing a performance-tuned or adjustable suspension option, or anyone whose vehicle is not listed in the fitment notes; always confirm fitment with the vehicle details before purchasing. Also consider other products if corrosion resistance beyond standard protective coating is a priority in extreme coastal environments.
