HD Pro Aluminium 9" Center Section Fully Assembled with 3.89 Ratio
Aluminium Case & Pinion Support, 35-Spline Eaton TrueTrac, 1350 Chrome Moly Yoke

The Strange HD Pro Ford 9 inch Aluminium Third Member with differential is designed for drag race applications and for the most abusive Hi-Performance street/strip applications. As with all Strange aluminium cases, it is crafted from 206-T4 heat treated aluminium. This premium aluminium has a 12% higher yield strength and a 32% higher tensile strength compared to commonly used 356-T6 aluminium.

The billet aluminium pinion support has a unique oil channel that is machined 360° into the support to maximize oil flow to the pinion bearings as well as a large slot in the front to further boost oil circulation. The support is in contact with the bore of the case in two locations as opposed to one as found in normal cases. This additional contact area holds the pinion shaft much more securely resulting in better bearing and gear life. The tail bearing is oversized to handle more load and greater RPM than a stock tail bearing. Billet aluminium main caps encapsulate chrome-moly studs, provide the utmost support for the carrier bearings and significantly reduce ring gear deflection.
