Does it fit my Avalon?

It is built for the rear left of 2006–2007 Toyota Avalon. Check your model year and corner before ordering, since the right side is a separate part.

Do I need a spring compressor?

No. The strut, coil spring and mount come pre-assembled, so the unit installs as one piece.

Should I replace both rear sides?

KYB sells each corner separately. Replacing both sides together keeps damping and ride height even across the rear axle.

Is this a performance upgrade?

No. It is an OE-style replacement that restores stock ride height and handling rather than lowering or stiffening the car.

One complete rear-left strut and coil spring assembly. Mounting hardware is not included unless stated.

About the KYB SR4407 Suspension Strut and Coil Spring Assembly - Rear Left

The KYB Strut-Plus SR4407 is a pre-assembled suspension strut and coil spring assembly for the rear left position on select Toyota Avalon models. It is an OE-style replacement designed to restore ride height, handling response and vehicle control. It is intended as a direct replacement for the rear left assembly.

The assembly includes a KYB Excel-G strut with application-specific damping valves and a high-carbon steel coil spring. The strut has a stronger steel outer shell for added structural support. The design is side-specific, with separate left and right parts, and it is engineered to work with electronic safety systems such as ESC and ABS.

It fits the 2007 Toyota Avalon rear left, and the 2006 Toyota Avalon rear left from 1/2006. Check the side, position and build date before installation, and follow the manufacturer's instructions for replacement. It is intended for professional installation.
