UMI Performance 90074 Engine Mount Clamshell Set for 1973-1981 GM F-Body Small Block Chevy

UMI Performance 90074 Heavy Duty Engine Mount Clamshells

The UMI Performance 90074 engine mount clamshell set is engineered specifically for 1973-1981 GM F-Body vehicles equipped with Small Block Chevy engines. These heavy-duty mounts replace the factory clamshell design while maintaining the engine in its exact factory position, ensuring proper fitment and alignment.

Heavy-Duty Construction

Built to withstand high-horsepower applications, these engine mount clamshells are fabricated from tough 3/16-inch laser-cut steel brackets and include Grade 8 hardware for maximum strength and durability. The precision laser-cutting process ensures consistent fitment and reliability under demanding conditions.

Versatile Mounting Options

The 90074 clamshell mounts are designed to work with either UMI's solid motor mounts (P/N 90051) or factory rubber mounts, giving you the flexibility to choose the mounting style that best suits your application. When paired with solid engine mounts, these clamshells improve throttle response and reduce engine movement, making them ideal for high-performance builds with large header primaries or turbocharger installations where tight packaging is critical.

Professional Finish and Quality

Each engine mount clamshell set features a durable gloss black powder coat finish that resists corrosion and provides a clean, professional appearance in the engine bay. Proudly manufactured, tested, and raced in Philipsburg, Pennsylvania, USA, these mounts meet UMI Performance's exacting standards for quality and performance.

Applications

• 1973-1981 Chevrolet Camaro (2nd Gen F-Body)
• 1973-1981 Pontiac Firebird/Trans Am (2nd Gen F-Body)
• Small Block Chevy (SBC) engines

Note: When using solid engine mounts, increased noise, vibration, and harshness (NVH) is expected. Solid mounts are recommended primarily for racing applications.
