Mardarth engine motor mount set for 2007–2014 Tahoe, Silverado, Suburban, Sierra — heat-shielded

Mardarth 15854941 engine motor mounts are a pair of vibration-damping, heat-shielded mounts engineered to secure and isolate the engine in 2007–2014 GM full-size trucks and SUVs.

If your Tahoe, Silverado, Suburban, Sierra or Yukon is showing excess engine movement, noise or drivetrain feedback, replacing worn motor mounts with a matched set restores proper alignment and reduces vibration transferred to the chassis. This Mardarth set fits a range of GM models and includes heat shields and anti-freeze-lined rubber for improved longevity under heavy use.

Which vehicles and model years are compatible?

The Mardarth 15854941 mounts are compatible with many GM full-size trucks and SUVs from the 2007–2014 era. They fit both 1500-series and equivalent platforms where the OEM part numbers correspond.

• Cadillac Escalade 2007–2014

• Silverado 1500 and Sierra 1500 2007–2013

How do these motor mounts reduce vibration and noise?

Each mount uses a rubber lining treated for antifreeze resistance to damp engine movement and isolate road and engine vibrations from the frame. The integrated heat shield protects the mount from nearby exhaust or engine heat, extending service life.

• Anti-freeze–resistant rubber reduces deterioration from coolant exposure
• Heat shield deflects radiant heat and nearby hot components
• Sturdy bracket design keeps engine alignment steady under load
