Product Details

KYB designed the Strut-Plus line to restore the handling and control characteristics of the original suspension setup. The SR4450 combines an OE-restoring KYB strut with a high-carbon steel coil spring selected around vehicle attributes and corner weights to help return ride height to OE specifications. For 2010 Toyota Highlander front right service, as well as 2008-2009 Toyota Highlander front right replacement, this assembly supports consistent suspension geometry and predictable steering feel. This part cross-references Monroe Shocks & Struts (e.g., 172483) for the same application.

Common Problems This Part Addresses

• Excessive bouncing or reduced damping control
• Uneven ride height from a fatigued coil spring
• Noisy or worn front suspension components
• Loose steering feel or reduced cornering stability
• Suspension performance issues after strut wear on the front right side

Installation Notes and Tips

Install according to the vehicle manufacturer’s instructions and verify side-specific placement before service. This assembly is pre-assembled for professional results, which can reduce the need to transfer spring components during replacement. After installation, confirm alignment and inspect related suspension parts for wear.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered to restore OE-level ride height, handling, and control characteristics. The SR4450 is built with application-specific damping and a high-carbon steel spring to match the vehicle’s suspension requirements.
