Product Details

KYB Strut-Plus SR4728 is built for the front left corner of the Subaru Legacy and is engineered to restore the vehicle’s original ride height and suspension control characteristics. As an original equipment supplier, KYB applies OE-based design targets to the strut assembly, while the coil spring is developed to match vehicle-specific weight distribution and corner loading. This helps maintain proper stance, steering pivot function, and overall stability in the suspension system. The SR4728 is a practical choice for a 2013-2014 Subaru Legacy front left strut and spring replacement when the goal is to return the vehicle to factory-style suspension geometry.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Replacement Reasons

• Front-end noise from a worn strut assembly
• Sagging ride height on the front left corner
• Excessive bounce, body movement, or reduced damping control
• Uneven steering feel or unstable road manners
• Need for a complete Subaru Legacy front left suspension strut and coil spring assembly

Installation Notes

Install SR4728 on the front left position only for the listed Subaru Legacy applications. Verify compressed length, extended length, and stroke length against the original assembly before installation. Because this is a suspension strut and coil spring assembly, alignment should be checked after replacement to confirm proper ride height and steering geometry.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered to restore handling and control using OE-based strut design and vehicle-matched spring rates. The included boot helps protect the strut shaft from road debris and contamination.
