Gabriel G57790 Ultra ReadyMount Rear Left Strut Assembly - Fast

Our review of the Gabriel G57790 Ultra ReadyMount rear left complete strut assembly focuses on drivers of 2011-2013 Toyota Highlander FWD who want a quick, reliable repair without special tools. The biggest reason to buy is that this is a fully preassembled unit that replaces the entire strut assembly so installation is faster and safer than compressing a spring on the job; the review finds it especially useful for DIYers and independent shops that need a direct-fit replacement with minimal fuss. The ReadyMount approach reduces installation time and handles the common fit and ride concerns for this vehicle application.

Key Features

• Preassembled ReadyMount: Arrives with upper mount, boot, bumper, coil spring and Ultra strut already assembled to save time and avoid spring compression risks.
• Vehicle Fitment: Designed specifically for 11-13 Toyota Highlander FWD so buyers get a factory-style fit without modification.
• Durable construction: Built as a complete OE-style replacement intended for long-term use and consistent ride performance.
• Clear interchange numbers: Uses interchange part numbers such as G57790 and SR4453 so you can confirm compatibility with existing parts lists.
• Concrete dimensions: Measured stroke and lengths (stroke 8.15 in, extended 26.34 in, collapsed 18.19 in) give installers confidence the geometry matches the vehicle.

Who It's For

This ReadyMount unit is best for DIY mechanics, independent repair shops, and Highlander owners who need a direct-fit rear left strut replacement for 2011-2013 FWD models and want to avoid spring compressors.
