Speedmaster 1-214-007 Ford 9 Inch 3.06 Heavy Duty Nodular Steel N Case Third Member Dropout

The Speedmaster 1-214-007 is a heavy-duty third member case designed for Ford 9-inch rear axle applications. Engineered for high-performance and racing builds, this dropout housing features a robust 3.06-inch register bore to accommodate large ring gears and heavy-duty differential assemblies.

Key Features:

• Constructed from premium nodular iron for superior strength and durability compared to standard cast iron
• Heat-treated and stress-relieved before CNC machining to minimize internal stresses and prevent warping
• 3.06-inch register bore supports large ring gear applications
• N-case design provides maximum load capacity for racing and heavy-duty street use
• Precision CNC-machined mounting surfaces ensure proper gear alignment and reduced noise
• Direct replacement for Ford 9-inch third member housings

This GT-HO spec third member case is ideal for drag racing, road racing, and extreme street applications where axle strength is critical. The nodular iron construction provides exceptional resistance to shock loads and flexing under hard acceleration and cornering forces.
