Product Line Details

Unity Automotive’s pre-assembled complete strut assembly line is built for straightforward suspension replacement. This product line combines the strut, coil spring, and top mount into one ready-to-install unit, making it a practical choice for rear suspension service on vehicles such as the Dodge Caliber, Jeep Compass, and Jeep Patriot.

Detailed Description

Unity 15580 is engineered as a rear suspension strut and coil spring assembly for vehicles that use a complete strut design at the rear. It is listed for 2007-2017 Jeep Compass rear, 2007-2017 Jeep Patriot rear, and 2007-2012 Dodge Caliber rear, with exclusions for Offroad Package Compass and Patriot models and SRT-4 Caliber models. The assembly is fully assembled and ready to install, which supports faster replacement compared with rebuilding individual suspension components. Unity Automotive brings more than 40 years of aftermarket suspension manufacturing experience and offers broad coverage across thousands of suspension SKUs. This part cross-references Monroe Shocks & Struts (e.g., 172401, 182401) for the same application.

Common Problems This Part Can Address

• Rear ride height loss from a fatigued coil spring
• Excessive rear suspension noise from worn strut components
• Uneven rear damping response on high-mileage vehicles
• Rear-end instability over bumps and rough pavement
• Time-consuming suspension rebuilds when a complete assembly is preferred

Installation Notes and Tips

Verify rear fitment by year, make, model, and package before installation. This assembly is not for Compass or Patriot vehicles with the Offroad Package, and it does not apply to Dodge Caliber SRT-4 models. Confirm the existing rear suspension configuration and compare dimensions before final installation. Part number 15580 is intended for direct replacement on the listed rear applications.
