About the Strut-Plus Line

KYB Strut-Plus assemblies combine a KYB OE-restoring strut with a matched coil spring and side-specific components. The line is built for vehicles that need a direct suspension replacement with factory-style geometry, including Jeep Compass and Jeep Patriot front left applications such as SR4508.

Detailed Description

KYB designs the SR4508 as a suspension strut and coil spring assembly that addresses the functions a front strut performs: supporting vehicle weight, setting ride height, acting as a steering pivot, and helping maintain stability. For 2011-2016 Jeep Compass front left and 2011-2017 Jeep Patriot front left applications, this assembly is built to restore handling characteristics and maintain the original suspension position. The KYB SR4508 uses an OE-restoring KYB strut, a precision damping valve setup, and a high-carbon steel spring chosen around vehicle-specific corner weights. This part cross-references Monroe Shocks & Struts (e.g., 272951) for the same application.

What It Helps Address

• Front-end sag or reduced ride height on the left side
• Loose or inconsistent steering feel
• Excessive body movement over bumps and dips
• Worn strut performance that affects stability
• Suspension replacement needs on Jeep Compass and Jeep Patriot front left positions

Installation Notes and Tips

Fits 2017 Jeep Compass, front left. Fits 2011-2017 Jeep Patriot, front left. Fits 2011-2016 Jeep Compass, front left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify side, year, and body code before installation, especially on 2017 Jeep Compass applications with MK body code. Professional installation is recommended because the assembly affects ride height, steering geometry, and electronic safety system performance.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered to meet OE-style fitment and performance expectations for the listed Jeep applications. The SR4508 is assembled in the USA and built with side-specific components to match the vehicle’s original suspension design.
