KYB SM5972 Suspension Shock Absorber Mount - Rear Upper

KYB Rear Upper Strut Mount for Select GM Vehicles

KYB SM5972 is a rear upper suspension shock absorber mount built for select Buick, Cadillac, and Chevrolet applications. It replaces worn vibration insulators that can transmit noise and harshness into the cabin, while helping restore a quieter, more controlled ride.

Compatible with 2021-2025 Buick Envision, 2019-2025 Cadillac XT4, and 2016-2025 Chevrolet Malibu in the rear upper position, this KYB Mount Components part is made as an OE-quality replacement for the original mount assembly.

Key Features

• OE-quality replacement suspension shock absorber mount
• Helps reduce road vibration, noise, and harshness from worn mounts
• Supports suspension performance at the rear upper mounting point
• Built for select Buick, Cadillac, and Chevrolet fitments
• KYB Mount Components line for application-specific replacement parts

Product Details

KYB SM5972 is engineered for rear upper suspension use on vehicles such as the Buick Envision, Cadillac XT4, and Chevrolet Malibu. KYB designs its strut mounts to replace hardened insulators that no longer isolate vibration effectively, helping the suspension operate with the original mounting geometry and feel. Front bearing plates are critical steering pivots, but this rear upper mount is focused on isolating impact and reducing noise transfer at the rear suspension attachment point. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Address

• Clunking or knocking from a worn rear upper mount
• Excess vibration felt through the body or cabin
• Noise caused by hardened or deteriorated vibration insulators
• Harshness over bumps from reduced suspension isolation
• Uneven ride feel from aging mount components

Installation Notes and Tips

Verify the rear upper position and confirm vehicle fitment before installation. Inspect surrounding suspension components, fasteners, and related hardware for wear or damage during service. For best results, replace worn mount components when addressing suspension noise or vibration on the same axle.

Quality Assurance

KYB is known for OE-style replacement suspension components, and the SM5972 is built to match the application-specific requirements of select GM vehicles. It is intended to restore proper mount function and help maintain suspension performance on compatible Buick, Cadillac, and Chevrolet models.
