Product Details

KYB Excel-G is engineered to restore the factory-tuned behavior of the suspension rather than alter it. For the Subaru Crosstrek, rear strut performance affects body control, braking stability, and how the vehicle responds during quick direction changes. The 3410090 rear suspension strut uses the same OE-quality construction standards found in KYB original equipment production, making it a practical replacement for worn rear struts on 2018-2019 Subaru Crosstrek models. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems This Part Can Address

• Excessive bouncing or oscillation after bumps
• Reduced rear-end stability during braking or cornering
• Uneven or unsettled ride quality from worn suspension damping
• Delayed response during lane changes or evasive maneuvers
• Noise or harshness associated with aging rear struts

Installation Notes and Tips

Verify rear fitment against the vehicle’s suspension configuration before installation. Compare the original strut dimensions, upper mount style, and lower mount type to confirm the correct replacement. After installation, a professional wheel alignment is recommended to help maintain proper handling and tire wear. For 2018-2019 Subaru Crosstrek rear suspension service, confirm that the replacement matches the original OE application before final assembly.
