Anchor 300573 Engine Mount Kit

Engine Mount Kit for GM Trucks

Anchor 300573 is an engine mount kit built for select Chevrolet and GMC truck applications from 1978-1981. It supports the engine, helps control vibration, and is engineered to OEM standards for consistent fit and performance.

Key Features

• Engine mount kit for select Chevrolet C10, C10 Suburban, and C30 applications, plus GMC C1500 and C1500 Suburban models
• Made in USA engine mounts
• Uses natural rubber and Styrene Butadiene rubber for abrasion resistance and aging stability
• CAD/CAM-engineered to OEM standards for consistent quality
• Chemlock bonding agent helps create a durable rubber-to-metal bond
• Rubber hardness is matched to vehicle application requirements
• Hydraulic mount design is used where OE specifications call for added vibration and torque control

Detailed Description

Anchor 300573 is a direct-fit engine mount kit for classic GM truck platforms, including 1978-1981 Chevrolet C10, 1978-1980 Chevrolet C10 Suburban, 1978-1981 GMC C1500, 1979-1981 GMC C1500 Suburban, 1980 GMC C2500 Suburban, and 1978 Chevrolet C30. This part number is also referenced as Anchor 300573 for buyers searching by catalog number. The kit is designed to isolate engine movement and reduce vibration transfer through the chassis, helping maintain smoother operation in older truck drivetrains.

Construction details focus on durability and application-specific performance. Rubber compounds are selected for abrasion resistance and aging stability, while hardened steel fasteners and heat-treated Grade 5 bolts are used where included by the manufacturer. The mount design follows OEM-style engineering practices, and hydraulic mount construction is used on applications that require additional damping under load. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excess engine vibration felt in the cab or through the frame
• Engine movement during acceleration, braking, or shifting
• Noise caused by worn or collapsed engine mounts
• Drivetrain harshness in older Chevrolet C10 and GMC C1500 trucks
• Mount deterioration from age, heat, and road exposure

Installation Notes and Tips

Verify engine and transmission mount locations before installation, especially on vehicles with prior drivetrain repairs or modified components. Inspect surrounding brackets, crossmembers, and mounting surfaces for wear, cracks, or corrosion before replacing the mounts. For best results, compare the existing mount style to the replacement part before final assembly.

Quality Assurance

Anchor designs this mount kit to OEM standards using CAD/CAM engineering processes and application-specific rubber hardness targets. The use of natural and Styrene Butadiene rubber, along with Chemlock bonding, supports consistent rubber-to-metal adhesion and long-term service performance.
