Anchor 300563 Engine Mount Kit

Engine Mount Kit for GM Trucks and Vans

Anchor 300563 is an engine mount kit for automatic-transmission Chevrolet and GMC applications from 1979-1991. It is built to support the engine, reduce vibration transfer, and help maintain stable drivetrain alignment in demanding truck and van use.

• Engine mount kit for Chevrolet and GMC full-size truck and van applications
• Fits automatic transmission vehicles listed in the fitment data
• Engine mounts are made in the USA
• OEM-standard design using CAD/CAM engineering methods
• Natural rubber and Styrene Butadiene rubber construction for abrasion resistance and aging stability
• Chemlock bonding agent used for a stronger rubber-to-metal bond
• Hardened steel fasteners with heat-treated Grade 5 bolts where included
• Rubber hardness is matched to vehicle application requirements
• Hydraulic mount design used where OE specifies it for higher vibration and torque control

Detailed Fitment and Application

This Anchor 300563 kit is built for classic Chevrolet C10, C20, C30, R10, R20, R30, P20, P30, and GMC C1500, C2500, C3500, R1500, R2500, R3500, P1500, P3500 applications. It is also listed for Chevrolet and GMC Suburban and R-series models with automatic transmissions, including 1979-1991 Chevrolet R2500 Suburban, 1987-1991 GMC R3500, and 1990 Chevrolet R1500 Suburban. Anchor 300563 is engineered to match OE-style mounting geometry and vibration control requirements for these vehicles.

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

What It Helps Address

• Excess engine movement under load
• Cab and floor vibration from worn mounts
• Drivetrain misalignment after mount wear
• Noise caused by deteriorated rubber isolation
• Harshness during acceleration and shifting

Installation Notes

Verify automatic-transmission fitment and compare the existing mount style before installation. Inspect surrounding brackets, crossmembers, and fastener threads for wear or damage, and replace any worn mounting points before final torque. Because this kit is application-specific, confirm the vehicle year, make, and model against the fitment list before ordering.

Quality Assurance

Anchor manufactures these mounts to OEM standards using controlled engineering and material specifications. The rubber compound, bonding process, and hardness ratings are selected to support consistent fit and vibration isolation across the listed Chevrolet and GMC applications.
