KYB SRM4473 Suspension Strut and Coil Spring Assembly - Front Left

KYB Truck-Plus Assembly for Tundra

The KYB Truck-Plus Performance Assembly SRM4473 is a front left suspension strut and coil spring assembly for 2007-2021 Toyota Tundra models. It is built for the front-left corner where ride height, steering response, and vehicle stability all depend on the strut assembly working as a matched unit.

For Toyota Tundra owners searching for a front left strut and coil spring assembly, SRM4473 provides a direct replacement solution from KYB’s Truck-Plus Performance Assembly line. This product line is focused on truck-specific suspension needs rather than a one-size-fits-all design.

Product Details

The SRM4473 is engineered as a complete suspension strut and coil spring assembly for the front left position on the Toyota Tundra. Because this corner of the suspension carries vehicle weight and helps determine ride height, the assembly plays a direct role in steering pivot behavior, stability, and the way the truck responds over uneven pavement. KYB designs the Truck-Plus line around vehicle-specific requirements, which matters on a full-size truck like the Tundra where suspension geometry and load handling are critical.

This part number, SRM4473, is listed for 2007-2021 Toyota Tundra front left applications and is also referenced for MonoMax and Maximum Monotube Performance Upgrade use cases in the fitment data. If you are replacing a worn front left strut assembly on a Toyota Tundra, SRM4473 is a direct-fit suspension service part for that position.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

• Front-end sag or uneven ride height
• Excessive bounce or poor damping response
• Steering instability from a worn strut assembly
• Noisy or tired suspension behavior at the front left corner
• Restoration of suspension geometry after strut wear

Installation Notes and Tips

Install SRM4473 only on the confirmed front left position for the listed Toyota Tundra applications. Verify year, model, and side before ordering, and compare the compressed length, extended length, and stroke length to the original assembly during inspection. Because this is a strut and coil spring assembly, proper suspension handling and alignment procedures are important after installation.

Quality Assurance

KYB builds the Truck-Plus Performance Assembly line as a vehicle-specific replacement solution for truck suspension service. The brand’s focus on application-specific engineering helps support consistent fitment and suspension function on the Toyota Tundra platform.
