For buyers searching for an engine mount kit for a 1975-1981 Chevrolet C20 or a 1979-1981 GMC C2500, Anchor 300556 provides an OE-style replacement built around application-specific fitment and vibration control.

Key Features

• Engine mount kit for automatic transmission applications
• Supports the engine and helps dampen vibration
• Engineered to OEM standards using CAD/CAM-based design processes
• Uses natural rubber and styrene butadiene rubber for abrasion resistance and aging stability
• Rubber hardness is matched to vehicle application requirements
• Chemlock bonding agent is used for a stronger rubber-to-metal bond
• Hydraulic mount design is used where OE application calls for higher vibration and torque control
• Made in USA engine mounts

Detailed Description

Anchor 300556 is designed for classic GM rear-wheel-drive platforms where engine movement and drivetrain vibration need to be controlled under load. The mount construction follows OEM-style engineering practices and uses rubber compounds selected for durability, consistent hardness, and long service life. Where the original application uses hydraulic-style isolation, the design addresses higher vibration and torque demands with fluid-filled damping.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Excess engine vibration felt through the chassis
• Engine movement during acceleration or shifting
• Noise caused by worn or collapsed mounts
• Misalignment between engine and transmission mounting points
• Rubber deterioration from age, heat, and road exposure

Installation Notes and Tips

Verify automatic transmission fitment before ordering, since the listed applications are specific to that configuration. Confirm the mount locations against the vehicle’s existing hardware and compare the old mounts to the new parts before installation. On vehicles with worn drivetrain components, inspect adjacent mounts and brackets so the new engine mount kit can seat correctly and maintain proper alignment.

Quality Assurance

Anchor builds this mount kit to OEM standards using controlled rubber hardness, hardened steel fasteners where supplied, and a bonded rubber-to-metal construction method for consistent performance. The product is made in the USA for the engine mount applications listed.
