Product Details

Unity Automotive has more than 40 years of aftermarket suspension manufacturing experience, and the Gas Charged Shock Absorber line is built around OEM-style dimensions and application-specific fitment. This rear shock absorber is listed for 2003-2019 Toyota 4Runner rear applications excluding X-REAS Suspension and Kinetic Dynamic Suspension, 2020-2024 Toyota 4Runner rear applications excluding X-REAS Suspension and Kinetic Dynamic Suspension, and 2007-2014 Toyota FJ Cruiser rear applications.
