KYB Strut-Plus SR4584 Front Right

KYB Strut-Plus SR4584 is a pre-assembled suspension strut and coil spring assembly for the front right position on the 2008-2014 Scion xD. It is built to restore ride height, steering response, and stability with OE-style fitment for a direct replacement on this application.

• Includes a KYB Excel-G strut, a stronger steel outer shell, and application-specific damping valves
• Pre-assembled for exact fitment and professional results
• Side-specific design with left and right part numbers as the vehicle manufacturer intended
• Engineered to help vehicles with electronic safety systems such as ESC and ABS
• Recipient of a 2018 industry award in the import aftermarket category

Product Line Details

KYB Strut-Plus combines a KYB OE-restoring strut with a high-carbon steel coil spring selected around vehicle attributes and corner weights. That approach helps return the suspension to OE ride height and supports consistent handling on the Scion xD front right corner. The SR4584 is part of KYB’s Strut-Plus line for buyers who want a direct-fit suspension strut and coil spring assembly rather than building the unit from separate components.

What It Helps Address

• Front-end sag or uneven ride height on the passenger side
• Excessive bounce, nose dive, or reduced damping control
• Loose steering feel or unstable handling over bumps
• Noise or wear associated with a tired strut assembly
• Suspension performance changes that can affect ESC and ABS behavior

Installation Notes

Fits 2008-2014 Scion xD, front right. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. This part cross-references Monroe Shocks & Struts (e.g., 172441) for the same application. Verify side, position, and vehicle details before installation, and confirm alignment after replacement.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus design follows OE-style engineering for this application. The SR4584 is built to restore handling and control characteristics while maintaining the vehicle’s intended suspension geometry and ride height.
