KYB SM5762 Suspension Coil Spring Seat - Rear Upper

KYB Rear Upper Spring Seat for Expedition and Navigator

KYB SM5762 is a suspension coil spring seat and insulator built for rear upper applications on select Ford Expedition and Lincoln Navigator models. It replaces worn vibration insulators that can create noise and harshness in the suspension, while restoring OE-style fit and function.

For Ford Expedition and Lincoln Navigator owners searching for a rear upper spring insulator replacement, KYB Mount Components deliver application-specific coverage and suspension-focused design.

Key Features

• High-quality replacement spring insulator for rear upper suspension use
• Reduces squeaks, rattles, and vibration noise from hardened insulators
• Built to match or exceed original equipment design and quality
• Application-specific fitment for select Ford Expedition and Lincoln Navigator models
• KYB Mount Components line for suspension mounting and isolation parts

Product Details

KYB SM5762 is engineered as an OE-quality suspension coil spring seat for vehicles that use a rear upper insulator. The part is designed to isolate the spring from the body or suspension contact points, helping maintain quieter operation and more consistent suspension performance. KYB spring seats and insulators are known for replacing aged, hardened components that no longer absorb vibration effectively.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Compatible With 2007-2017 Lincoln Navigator, rear upper with insulator; except self leveling, and 2007-2016 Ford Expedition, rear upper with insulator; except air suspension. It also fits 2017 Ford Expedition, rear upper; except air suspension. Search terms such as KYB SM5762 rear upper spring seat, Ford Expedition rear upper spring insulator, and Lincoln Navigator suspension coil spring seat apply to this part.

What It Helps Address

• Squeaks from worn spring insulators
• Rattles caused by hardened suspension mounting material
• Vibration noise transmitted through the rear suspension
• Loss of isolation at the spring seat contact point
• Fitment issues from deteriorated OE-style insulators

Installation Notes

Verify rear upper position and suspension configuration before installation. This part is listed for Expedition models except air suspension and Navigator models except self leveling, so confirm the vehicle’s suspension setup against the fitment notes. Inspect the surrounding spring and mounting surfaces for wear before reassembly.

Quality Assurance

KYB Mount Components are built with design and quality intended to match or exceed original equipment standards for the listed applications. SM5762 is part of KYB’s suspension-focused replacement line, developed to restore proper isolation and reduce unwanted noise in the rear upper spring area.
