Mardarth Engine Motor Mount 15854941 for 2007–2014 Chevrolet/GMC/Cadillac — Heat Shield, Rubber Isolator

Mardarth 15854941 is a replacement engine motor mount with heat shield and rubber lining engineered to secure the engine while minimizing vibration for select 2007–2014 GM full-size trucks and SUVs.

This motor mount is built to restore factory-like engine support in vehicles such as the Chevrolet Tahoe, Suburban, Silverado 1500, GMC Sierra 1500, Yukon and Cadillac Escalade and Avalanche where the original mount shows wear. It combines a stamped heat shield and anti-freeze-rated rubber isolator to reduce transfer of engine movement to the chassis, improve drivability, and protect nearby components from excessive motion. The part cross-references common OEM numbers so you can confirm fitment before purchase.

Which vehicles and model years does this mount fit?

This motor mount suits a range of GM full-size trucks and SUVs from the late 2000s to mid-2010s. Confirm compatibility using your vehicle make, model, and year against the listed applications and cross-reference numbers.

• Chevrolet Silverado 1500: 2007–2013
• Chevrolet Tahoe and Suburban 1500: 2007–2014
• GMC Sierra 1500 and Yukon/Yukon XL 1500: 2007–2014
• Cadillac Escalade 2007–2014 and Avalanche 2007–2013

How does the design reduce noise, vibration, and harshness (NVH)?

The mount uses an anti-freeze-rated rubber lining bonded to a metal housing with a heat shield to absorb and dissipate engine motion. That combination dampens vibration before it transfers to the frame, reducing audible rattles and harshness during idle and acceleration.

• Rubber isolator tailored for temperature resilience
• Stamped heat shield protects surrounding components
• Rigid metal housing keeps alignment under load
