KYB Strut-Plus SR4556 Overview

The KYB Strut-Plus SR4556 is a complete front left suspension strut and coil spring assembly built for direct replacement on select Chrysler and Dodge vehicles.

Key Features

• Complete strut assembly from KYB, a trusted OE-quality shock and strut supplier
• Includes a KYB Excel-G strut, stronger steel outer shell, and precision-designed damping valves
• High-carbon steel coil spring helps restore ride height to OE specifications
• Pre-assembled for exact fitment and professional results
• Engineered to help vehicles with electronic safety systems such as ESC and ABS

Product Details

The KYB Strut-Plus line is built around OE-restoring suspension design. For the SR4556, KYB pairs its Excel-G strut with a vehicle-specific coil spring developed around corner weights and vehicle attributes, helping the suspension return to the intended stance and handling balance. This makes the SR4556 a practical choice for Chrysler 200, Dodge Avenger, and Chrysler Sebring front left suspension service where ride height, steering pivot function, and stability are important.

This part cross-references Monroe Shocks & Struts (e.g., 171131, 271131) for the same application. The KYB SR4556 is a direct-fit replacement for drivers looking for a front left strut and coil spring assembly that matches the original suspension layout.

What It Helps Address

• Front-end sag or reduced ride height
• Loose, unstable, or inconsistent handling
• Excessive bounce or poor damping response
• Steering feel changes caused by worn strut assembly components
• Suspension wear that can affect ESC, ABS, and related systems

Installation Notes

Install the KYB SR4556 on the front left side only for the listed applications. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions, and verify alignment after installation. Confirm vehicle fitment by year, make, model, and position before service.

Quality Assurance

KYB supplies original equipment and OE-style suspension components, and the Strut-Plus line is engineered to restore handling and control characteristics while maintaining application-specific fit and ride height targets.
