Mastodon Ford 9" Rear End Housing Kit with Axles, 31 Spline, w/o Brackets 57" (1448mm)

Complete Ford 9" rear end housing kit with 31-spline axles. Supplied without mounting brackets — designed for high-performance builds where strength and reliability matter more than convenience. The 9" centre-section is the strongest production rear-end design ever offered, the standard upgrade for muscle-car restorations, pro-touring builds, and any application where the factory rear isn't going to survive what's in front of it.

Specifications:

• Width: 57" (1448 mm) flange-to-flange
• Axles: 31-spline (heavier-duty than common 28-spline)
• Brackets: Not supplied — order to suit your chassis
• Suits: Muscle-car conversions, pro-touring, drag, hot-rod, off-road builds

Confirm housing width against your chassis before ordering. Pair with appropriate trailing arms or 4-link kit for the build.
