Product Details

The MasterPro MRC Mounts A5940 is engineered for the front right engine mount location on Cadillac STS and Cadillac SRX models. As a hydraulic mount, it is designed to help isolate engine movement and reduce vibration transfer through the chassis. The steel construction and OE replacement layout support a factory-style fit for service replacement work.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. It also cross-references Marmon Ride Control A5940 and Pioneer Automotive Industries 615455. Search terms such as Cadillac STS front right engine mount and Cadillac SRX hydraulic engine mount A5940 are commonly used for this application.

What This Part Helps Address

• Excessive engine vibration felt in the cabin
• Clunking or shifting during acceleration and deceleration
• Worn or collapsed front right engine support
• Noise caused by deteriorated hydraulic mount internals
• Loss of proper engine alignment at the mount point

Installation Notes

Install in the front right position only. Verify the existing mount configuration, bracket alignment, and vehicle application before replacement. Mounting hardware is not included, so reuse or source the required fasteners as needed. Because this is an OEM replacement hydraulic mount, careful support of the engine during service is recommended.
