Product Details

KYB designs the Strut-Plus line as a complete suspension strut and coil spring assembly for drivers who need a direct-fit replacement that restores original ride height and handling balance. For the Scion tC, SR4580 combines a KYB OE-restoring strut with a high-carbon steel coil spring selected around vehicle-specific corner weights and ride characteristics. That approach helps return the suspension to OE specifications while maintaining the steering pivot and stability functions handled by the strut assembly. This part cross-references Monroe Shocks & Struts (e.g., 172390) for the same application. Search terms such as 2005-2010 Scion tC front right strut assembly, Scion tC suspension strut and coil spring replacement, and KYB SR4580 fitment all point to this application.

Common Issues This Part May Address

• Excessive front-end bounce or poor damping control
• Uneven ride height at the front right corner
• Loose or imprecise steering feel from worn strut components
• Reduced stability during braking, cornering, or lane changes
• Suspension noise caused by a worn strut and spring assembly

Installation Notes and Tips

Fits 2005-2010 Scion tC, front right. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Because this is a side-specific assembly, confirm front right placement before installation. After replacement, a wheel alignment is recommended to verify suspension geometry and steering wheel position.
