Product Details

KYB designs the Strut-Plus line as a complete suspension strut and coil spring assembly for drivers who need a direct OE-style replacement without rebuilding the unit separately. The SR4184 combines KYB’s Excel-G strut technology with a precision-valved damping setup and a vehicle-specific spring rate to help restore factory ride height and handling balance. For a Toyota Corolla front left strut replacement, this assembly supports consistent steering feel, body control, and suspension geometry.

This part cross-references Monroe Shocks & Struts (e.g., 472598, 482598) for the same application. The KYB SR4184 is a fitment-based replacement for 2009-2013 Toyota Corolla, front left, and is built around the original equipment layout for that corner of the vehicle.

Common Problems This Part Can Address

• Front-end bounce or excessive road shock
• Uneven or low ride height at the left front corner
• Loose steering response or reduced cornering control
• Noisy or worn suspension performance from an aging strut assembly
• Ride quality changes after the original strut and spring have weakened

Installation Notes

Fits 2009-2013 Toyota Corolla, front left. Verify side-specific placement before installation, since this assembly is engineered for the left front position only. Confirm that the vehicle matches the listed application and inspect related suspension components, alignment settings, and mounting points during replacement. Because this is a pre-assembled strut and spring unit, it is intended to simplify installation compared with rebuilding a strut from separate components.

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 inputs. The SR4184 is assembled in the USA and built with application-specific components selected for the 2009-2013 Toyota Corolla front left application.
