KYB SM5485 Front Upper Spring Seat

KYB SM5485 is a front upper suspension coil spring seat for select Toyota and Lexus applications. It is built to replace worn vibration insulators and restore quieter, more controlled suspension operation on vehicles such as the Toyota Camry, Toyota Sienna, Lexus ES350, and Lexus RX350.

Key Features

Replacement spring seat for front upper suspension locations
Helps reduce squeaks, rattles, and vibration noise from aged insulators
Built to match or exceed original equipment design and quality
OE-style replacement for select Toyota and Lexus strut assemblies
KYB Mount Components product line for suspension service

Product Details

The KYB Mount Components line focuses on suspension mounting parts that restore proper fit and function where original rubber and support components have hardened or deteriorated. SM5485 is engineered as a direct replacement spring seat/insulator component for front upper suspension service, helping maintain the intended isolation between the coil spring and the strut mount area. This part cross-references Monroe Shocks & Struts (e.g., 904950) for the same application.

Compatible With select Toyota and Lexus models including 2011-2020 Toyota Sienna, 2012-2017 Toyota Camry, 2013-2018 Lexus ES350, 2013-2018 Lexus ES300h, 2013-2018 Toyota Avalon, 2010-2015 Lexus RX350, 2010-2015 Lexus RX450h, and additional listed applications. Use the exact vehicle fitment below to confirm front upper placement and notes before ordering. KYB SM5485 is also listed for earlier Toyota Avalon, Camry, Sienna, Highlander, Solara, and Lexus ES/RX applications.

What It Helps Fix

Squeaking from worn spring seat or insulator material
Rattling or clunking at the front upper suspension area
Vibration noise transferred through aged mount components
Loss of suspension isolation caused by hardened rubber parts
Poor OE-style fit from deteriorated original spring seat components

Installation Notes

Install at the front upper suspension position only. Verify the vehicle year, make, model, and any notes such as insulator or air-suspension exclusions before installation. Because this part is used in strut and spring service, inspect related mount components and surrounding suspension hardware for wear during disassembly.

Quality Assurance

KYB states that its spring seats and insulators are designed as OE-quality replacement components for each application, with construction intended to match or exceed original equipment standards. The brand positions this Mount Components part line around restoring suspension performance and reducing noise caused by aged vibration insulators.

This part fits 156 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
