Product Details

KYB’s Truck-Plus Leveling Assembly line is focused on truck applications that need front-end leveling without using a one-size-fits-all strut. SR4473K is built for the Toyota Tundra front left position and is matched to the application rather than shared across multiple vehicles. Because the strut assembly carries vehicle weight, sets ride height, acts as a steering pivot, and influences stability systems, application-specific fitment matters. This part number is also referenced as KYB SR4473K for buyers comparing Toyota Tundra front left strut assembly options.

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

What It Helps Address

• Front-end sag or uneven ride height on a Toyota Tundra
• Worn strut assembly performance at the front left corner
• Reduced steering precision from a tired suspension strut
• Excessive body motion or instability over bumps
• Suspension noise or degraded ride quality from aging components

Installation Notes and Tips

Install SR4473K only on the confirmed front left position for 2007-2021 Toyota Tundra models with the TRD Package. Verify spring orientation, mounting points, and suspension condition before installation. Because this is a complete strut and coil spring assembly, it is important to confirm that the vehicle’s other front suspension components are in serviceable condition before final alignment.

Quality Assurance

KYB manufactures the Truck-Plus Leveling Assembly with corner-specific part numbers to match the intended vehicle application and restore designed suspension performance. The included boot adds protection for the strut shaft area, and the assembly is engineered around the demands of truck front suspension service.
