Product Details

KYB Strut-Plus SR4648 is built as a complete rear strut and spring assembly for Subaru Impreza applications. As an original equipment supplier, KYB uses OE-based engineering to restore handling, ride height, and stability. The spring rate and strut are matched to the vehicle’s rear suspension requirements, helping maintain the intended stance and steering/suspension response. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With 2008-2011 Subaru Impreza, rear. The SR4648 is a direct-fit style replacement for rear suspension service on these model years and is listed as a recommended OEM replacement.

Common Problems This Part Can Address

• Rear ride height that has dropped from worn springs
• Excessive bounce or poor rear damping control
• Reduced stability over bumps and uneven pavement
• Suspension noise from worn strut components
• Uneven rear stance caused by aging suspension parts

Installation Notes and Tips

Install the SR4648 on the rear of 2008-2011 Subaru Impreza models only. Verify side-to-side condition before replacement and inspect related rear suspension components, mounts, and fasteners during service. Because this is a strut and coil spring assembly, proper suspension handling procedures and alignment checks after installation are recommended.
