Detailed Description

Anchor 300550 is an engine mount kit for GM full-size trucks and Suburban models with automatic transmission. The kit is specified for 1987-1991 Chevrolet and GMC applications listed in the fitment data, including front left, front right, and rear transmission mount positions referenced by the included application notes. Built to OEM standards, the mounts use durable rubber compounds, heat-treated Grade 5 fasteners where supplied, and bonded construction to maintain engine location while reducing vibration transfer through the chassis.

This part number 300550 is a direct-fit service option for owners replacing worn mounts on Chevrolet C1500, C2500, C3500, and GMC C1500, C2500, C3500 trucks, along with compatible Suburban and V-series applications shown below.

What It Helps Address

• Excess engine vibration felt in the cab
• Clunking or movement from deteriorated mounts
• Engine misalignment caused by collapsed rubber
• Noise transfer during acceleration and shifting
• Wear related to aging transmission and engine support points

Installation Notes and Tips

Verify automatic transmission fitment before installation. Match the vehicle year, make, model, and the notes shown for each application, especially the 1st design listing for 1988 Chevrolet V30 and 1988 GMC V3500. Inspect adjacent brackets and mounting surfaces for wear, corrosion, or damage before installing the new mounts. Confirm the engine is properly supported during removal and replacement.

Quality Assurance

Anchor designs these mounts to OEM standards using controlled rubber hardness, bonded construction, and application-specific engineering. The use of natural and Styrene Butadiene rubber, along with Chemlock bonding and hydraulic mount design where required, supports consistent vibration control and long service life. Part number 300550 is built for the listed Chevrolet and GMC applications.
