Key Features

• Complete strut and coil spring assembly for suspension service

• Internal rebound spring included for controlled suspension movement

Product Details

The KYB Strut-Plus line combines a strut and coil spring in one assembly to simplify suspension replacement while restoring the vehicle’s original ride characteristics. For the Toyota Avalon, this assembly is engineered to help return proper ride height and support the steering and stability functions that depend on a correctly operating strut. Part number SR4743 is specified for the rear right position and is built around OE-restoring KYB components.

As an original equipment supplier, KYB applies OE-focused design standards to this Strut-Plus assembly. The spring is developed using vehicle attributes and corner weights so the finished unit aligns with OE specifications as closely as possible. The included boot and internal rebound spring add functional support to the assembly’s overall design.

What It Helps Address

• Sagging ride height from worn suspension components
• Excessive body motion during braking, cornering, or uneven road travel
• Reduced steering and stability control from a worn strut assembly
• Noisy or inconsistent suspension operation caused by aging internal parts
• Loss of factory ride feel in the rear suspension

Installation Notes

Verify fitment by year, make, model, and rear right position before installation. Compare the removed assembly to the new unit and confirm the compressed length, extended length, and stroke length match the application requirements. Because this is a complete strut and spring assembly, it is intended to replace the worn suspension unit as a single service component.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus SR4743 is engineered with OE-restoring components and spring specifications to support factory-level ride height and control. Part number SR4743 is built for consistent fitment on the listed Toyota Avalon application.
