Gabriel G57091 Ultra ReadyMount Rear Right Strut Assembly

In this review of the Gabriel G57091 Ultra ReadyMount rear right complete strut assembly, the bottom line is simple: this is for DIYers and independent shops that want a safe, time-saving replacement that fits 00-05 Hyundai Sonata and 01-06 Kia Magentis/Optima models. The preassembled unit eliminates spring compression and reduces installation time, so the single biggest reason to buy is the combination of ease of installation and a factory-style fit that restores ride quality without special tools.

Key Features

• Preassembled ReadyMount: Ships as a complete strut assembly so the installer does not need a spring compressor, speeding up the job and reducing risk.
• OE-style Ultra strut: The included Ultra strut is designed to deliver consistent damping and improved ride quality over worn originals.
• Complete hardware included: Upper mount, bumper, boot, coil spring and spring seat are all fitted, meaning no extra parts are required at installation.
• Direct vehicle fitment: Specifically made to fit 00-05 Hyundai Sonata and 01-06 Kia Magentis and Optima, ensuring correct alignment and geometry for those models.
• Durability focus: The preassembled design and quality components target long-term function and safe operation under normal driving conditions.

Who It's For

This strut assembly is best for owners of the listed Hyundai and Kia sedans who prefer a straightforward, do-it-yourself replacement or a fast swap by an independent mechanic. The ReadyMount format suits anyone who wants to avoid spring compression and save shop time, particularly when replacing a single corner.

It is less appropriate for vehicles outside the specified model years, for those needing a performance-tuned suspension upgrade, or for buyers who require an OEM-branded part number match beyond the interchange list; check compatibility by model year and side before ordering.
