Anchor 3647 Engine Mount - Front Left

Engine Mount for Front Left Applications

Anchor 3647 is a front left engine mount built for OE-style replacement on select Chevrolet and GMC trucks and SUVs. It supports the engine, helps isolate vibration, and is engineered for consistent fit and function in demanding daily driving conditions.

• Front left engine mount for select Silverado, Sierra, Tahoe, and Yukon applications
• Hydraulic design helps reduce noise and vibration at the mount point
• Stamped steel construction with painted black housing and semi-gloss finish
• Rubber bushing material for vibration control and abrasion resistance
• Heat shield included for added protection in high-heat areas
• Engineered to OEM standards using CAD/CAM-based design processes
• Uses natural and Styrene Butadiene rubber for aging stability and service life
• Chemlock bonding agent helps create a durable rubber-to-metal bond

Fitment Details

Compatible with front left applications on 2007-2013 Chevrolet Silverado 1500, 2008-2013 Chevrolet Silverado 2500, 2007-2013 GMC Sierra 1500, 2007-2009 Chevrolet Tahoe, 2007-2009 GMC Yukon, 2007 Chevrolet Silverado 1500 Classic, and 2007 GMC Sierra 1500 Classic. Anchor 3647 is a direct-fit option for these vehicle platforms when replacing a worn hydraulic engine mount.

This part cross-references Pioneer Automotive Industries 605440 and SKP SKM3232 for the same application.

What This Part Helps Address

• Excess engine movement under load
• Cabin vibration felt at idle or during acceleration
• Clunking or shifting caused by a deteriorated mount
• Rubber separation or fluid loss in a worn hydraulic mount
• Heat-related wear in the front left mount location

Installation Notes

Install Anchor 3647 in the front left position only and verify mounting hole alignment before tightening fasteners. Inspect the surrounding bracket, frame contact points, and nearby heat sources during replacement. Because this is a hydraulic mount, confirm the replacement matches the original mount style and orientation for the Silverado, Sierra, Tahoe, or Yukon application.

Quality Assurance

Anchor designs this mount to OEM standards with application-specific rubber hardness, steel hardware specifications where supplied, and bonded rubber-to-metal construction for consistent performance. The hydraulic design is used where OE applications require additional damping for vibration and torque control.
