• Stamped steel construction with painted finish
• Rubber bushing material for controlled movement and isolation
• Black housing and black bushing color
• Heat shield included for added thermal protection
• Engineered to OEM standards using CAD/CAM processes
• Natural and Styrene Butadiene rubber for abrasion resistance and aging stability
• Chemlock bonding agent for a durable rubber-to-metal bond
• Standard replacement design with 7 mounting holes

Detailed Description

Anchor 3649 is a front left engine mount designed for heavy-duty Chevrolet Silverado and GMC Sierra trucks that need stable engine support and vibration control. The hydraulic construction uses special fluid to dampen excess noise and vibration, while the steel bracket and stamped housing provide the structure needed for demanding truck applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Anchor 3649 is a direct-fit replacement choice for drivers servicing the engine mount on 2001-2010 Chevrolet Silverado 2500 HD, 2007-2010 Chevrolet Silverado 3500 HD, 2001-2010 GMC Sierra 2500 HD, and 2007-2010 GMC Sierra 3500 HD models, along with the 2007 Classic and 2001-2006 3500 applications listed in the fitment data.

What It Helps Fix

• Excess engine vibration felt in the cab
• Clunking or shifting during acceleration and load changes
• Engine movement caused by worn rubber or hydraulic mount components
• Noise transfer from the engine to the chassis
• Mount deterioration from age, heat, and road exposure

Installation Notes and Tips

Verify front left position before installation and compare the mount to the original part for bracket shape, hole count, and mounting geometry. Inspect surrounding brackets, fasteners, and heat shielding for wear or damage before reassembly. Because this is a hydraulic mount, handle it carefully and avoid damaging the housing or rubber bond during installation. Anchor 3649 is commonly searched as an engine mount for Chevrolet Silverado 2500 HD front left and GMC Sierra 3500 front left service work.

Quality Assurance

Anchor designs this mount to OEM standards and uses controlled rubber hardness, heat-treated Grade 5 fasteners where applicable, and a bonded rubber-to-metal construction to support consistent fit and durability. Part number 3649 is built for the specified GM truck applications and engineered for long-term vibration control.
