Restore the factory ride height and handling at one corner with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly (SR4406), a complete corner unit that drops in as a rear right replacement for the 2006-2012 Toyota Avalon. As an original equipment supplier, KYB engineered this pre-assembled Strut-Plus so a professional installer can bolt in a ready-to-go strut, mount and spring without compressing springs on the bench.
- Complete corner unit: combines a KYB Excel-G strut, mount and coil spring in one pre-assembled unit for exact fitment and professional results.
- High carbon steel coil spring: an application-engineered KYB spring developed around vehicle attributes and corner weights to help restore ride height within OE specifications and maintain it longer.
- Excel-G strut build: features a stronger steel outer shell and KYB's application-specific precision-designed damping valves.
- Side-specific design: left and right part numbers with side-specific components as the vehicle manufacturer intended, and engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.
The strut assembly supports vehicle weight, sets ride height, acts as the steering pivot and helps control stability. Winner of the 2018 Best Overall Import Aftermarket Product and KYB's #1 recommended OE replacement choice for Asian vehicles.
