Product Details

The KYB Strut-Plus line combines a KYB OE-restoring strut with a matched coil spring assembly to address ride height, stability, and suspension control in one service part. For a Toyota Corolla rear left strut replacement, SR4274 is engineered around the vehicle’s original suspension geometry so the finished assembly supports consistent handling and proper alignment characteristics. This part number, SR4274, is also a direct reference point for shoppers comparing Toyota Corolla rear left strut and coil spring assembly options.

This part cross-references Monroe Shocks & Struts (e.g., 171373L) for the same application.

What It Helps Address

• Rear suspension sag or uneven ride height
• Excessive bounce, body motion, or reduced damping control
• Noisy or worn strut and spring assembly service needs
• Steering and stability concerns tied to worn suspension components
• Restoration of OE ride characteristics on a 2003-2008 Toyota Corolla

Installation Notes

Compatible with 2003-2008 Toyota Corolla, rear left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Because this is a side-specific assembly, confirm left-side placement before installation. SR4274 is pre-assembled, which helps streamline replacement compared with rebuilding the original unit.

KYB is an original equipment supplier, and the Strut-Plus line is engineered to restore handling and control using OE-focused components and application-specific damping. The design also considers electronic safety systems such as ESC and ABS, making it a strong match for modern suspension service on the Toyota Corolla.
