Prothane 7-509-BL Polyurethane Engine Mount Insert Set GM Early Truck 1963-1972

The Prothane 7-509-BL is a polyurethane engine mount insert set engineered specifically for 1963–1972 GM early trucks. Unlike factory rubber mounts that deteriorate over time and allow excessive engine movement, these Prothane inserts are molded from high-quality black polyurethane for dramatically improved durability and performance.

Polyurethane engine mounts reduce unwanted engine torque movement under acceleration, helping deliver more power to the wheels and reducing the stress that excessive motor travel places on drivetrain components such as exhaust systems, motor brackets, and CV joints. This application-specific design ensures a proper fit with no modification required.

Key Features:

• Molded from durable black polyurethane for long-lasting performance
• Limits engine torque movement under hard acceleration
• Reduces chance of component breakage caused by excessive motor travel
• Improves power transfer efficiency to the drivetrain
• Application-specific engineering for a precise, no-modification fit
• Sold as a complete pair (2 mounts)
• Color: Black

Prothane is a leading manufacturer of polyurethane suspension and drivetrain components, trusted by performance enthusiasts and resto-mod builders alike. The 7-509-BL is an ideal upgrade for anyone restoring or building a classic GM truck who wants tighter, more responsive drivetrain performance.
