KYB SM5546 Front Upper Spring Seat

KYB SM5546 is a suspension coil spring seat for the front upper position on select Jeep, Ram, Dodge, and Mitsubishi applications. It is built as an OE-quality replacement to restore proper spring support and help reduce vibration-related noise at the suspension mount.

For drivers searching for a front upper spring seat for a 2013-2024 Ram 1500, 2005-2007 Dodge Dakota, or 2023-2025 Jeep Grand Cherokee L, this part number provides a direct-fit service replacement for the listed applications.

Key Features

• OE-quality replacement spring seat for the front upper suspension position
• Helps reduce squeaks, rattles, and vibration noise from aged insulators
• Built to match or exceed original equipment design and quality
• Part of KYB Mount Components for suspension service work
• Cross-reference: Monroe Shocks & Struts 907931 for the same application

Detailed Description

The KYB SM5546 spring seat is designed to support the coil spring at the front upper mount while helping isolate noise and vibration from worn suspension components. As rubber and related mount materials age, they can harden and lose their ability to dampen movement, which often leads to clunks, squeaks, and rattles. Replacing the seat with a properly matched OE-style component helps restore the suspension’s original feel and function.

This KYB spring seat is listed for applications including 2013-2024 Ram 1500, 2019-2024 Ram 1500 Classic, 2006-2010 Dodge Ram 1500, 2005-2007 Dodge Dakota, and select Jeep Grand Cherokee L, Grand Wagoneer, Wagoneer, and Wagoneer L models with front upper mounting and without air suspension where noted. The KYB SM5546 is also referenced by Dodge 55366975AA.

What It Helps Address

• Front suspension squeaks caused by worn spring seats or insulators
• Rattles and vibration noise from hardened mount components
• Loss of proper coil spring support at the upper mount
• Noise complaints after suspension service on Ram 1500 and Dodge Dakota platforms
• Wear-related ride harshness at the front upper spring location

Installation Notes and Tips

Verify the vehicle’s suspension configuration before ordering, especially on Jeep Grand Cherokee L, Grand Wagoneer, Wagoneer, Wagoneer L, and Ram 1500 models with air suspension exclusions. Confirm the front upper position and compare the original part to the replacement before installation. This part is intended for the listed applications only, so match year, make, model, and suspension setup carefully.

Quality Assurance

KYB is known for OE-quality suspension replacement components, and the Mount Components line is engineered for application-specific fit and performance. The SM5546 is built to provide the same type of support and noise isolation expected from a properly matched original-style spring seat.
