Aluminum Ford 9in. Housing

The Winters Aluminum Ford 9-inch Housing is a precision center section designed for performance builders and drag racing applications. This aftermarket differential housing replaces the factory Ford 9-inch unit with a lightweight aluminum construction, making it an excellent choice for racers aiming to reduce unsprung mass while maintaining durability and strength. Whether you're building a dedicated competition vehicle or upgrading a street machine, this housing provides the rigid foundation your drivetrain demands.

Constructed from premium-grade aluminum, the Winters housing offers weight savings compared to traditional cast-iron designs while ensuring the strength required for high-horsepower applications. The aluminum construction also enhances heat dissipation, which helps keep differential fluid temperatures lower during extended track sessions. Each housing is precision-machined to exacting tolerances, ensuring proper bearing preload and accurate gear mesh for consistent performance.

This housing is ideal for drag racing, road racing, and high-performance street builds where every detail matters. It accepts standard Ford 9-inch gears, bearings, and internal components, allowing you to retain or upgrade your gear ratio as needed. With a weight of 22.3 pounds, this assembly contributes to measurable improvements in acceleration and weight transfer characteristics.
