Building or rebuilding a Ford 9-inch rear end? This Yukon Gear Trac Loc case is the solid foundation you need. This is a bare carrier case – meaning it doesn't come with the spider gears, clutches, or side gears inside; it's just the strong iron housing itself. It's precision machined to tight tolerances, ensuring everything fits together perfectly for smooth operation and long life. It's designed for use with a Trac Lok limited-slip differential setup (the clutch-type LSD). It's compatible with both 28-spline and 31-spline axle setups and works with either 2-pinion or 4-pinion differentials. It uses the 4-tab clutch packs. This is a critical component, and Yukon is a trusted name in drivetrain parts, known for high-quality, high-strength components. If you're upgrading your differential or replacing a worn-out case, this is a professional-grade part that will handle serious power and abuse. Make sure you know exactly what you need for your specific Ford 9-inch build before ordering, but if this is the right part number, you're getting a top-notch piece.
