Product Details

KYB Strut-Plus SR4412 is part of KYB’s Strut-Plus product line, which combines a restoring strut with a matched coil spring for a complete suspension strut and coil spring assembly. For a Toyota Avalon rear left strut replacement, this design helps return the suspension to factory-style geometry and ride characteristics while reducing the need to source separate spring and strut components. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear suspension sag or uneven ride height

• Excessive bounce, float, or reduced damping control

• Noisy or worn rear strut assembly operation
