Detailed Description

KYB SR4204 is engineered for drivers who need a direct replacement suspension strut and coil spring assembly for the rear right side of a Toyota Corolla. The Strut-Plus line is designed around OE-restoring performance, using a KYB strut and a vehicle-specific coil spring selected to match corner weight and suspension geometry. That helps bring the Corolla back to proper ride height and consistent handling after wear from the original suspension components.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Compatible with 2009 Toyota Corolla, rear right, and 2010 Toyota Corolla, rear right, this KYB Strut-Plus assembly is a fitment-based replacement for the rear suspension on those vehicles. Part number SR4204 is also commonly searched as KYB SR4204 for Toyota Corolla rear right strut and spring assembly replacement.

What It Helps Address

• Sagging rear ride height
• Loose or unstable rear suspension feel
• Excessive bounce or poor damping control
• Uneven handling after strut and spring wear
• Suspension replacement needs on a Toyota Corolla rear right corner

Installation Notes and Tips

Install SR4204 on the rear right position only, following the vehicle manufacturer’s service procedure. Because this is a pre-assembled strut and coil spring assembly, it reduces the need to transfer spring components during replacement. Verify the vehicle build date and rear-right application before ordering, especially for 2010 Toyota Corolla models produced up to December 2010.

For best results, inspect related suspension components such as mounts, bushings, and tires during installation. After replacement, a wheel alignment is recommended to confirm proper suspension geometry and steering response.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered to restore handling and control characteristics using OE-focused design and application-specific damping. Part number SR4204 is built to support the suspension performance expected from the Toyota Corolla rear right application.
