Strange Engineering Nodular Iron 9" Center Section 3.250" Bearings

9'' Aluminum Case
For applications where weight is crucial and gear set life is not an issue, Strange offers the lightweight high-tensile aluminum alloy Ford 9'' case. This case, with forged 2014T-6 aluminum bearing caps, is a full 20 pounds lighter than the Strange nodular iron unit yet has greater tensile strength than a standard Ford 9" case.

9'' Iron Case
Chromemoly bearing caps retained by socket head cap screws that exceed aircraft Grade 8 specifications. Adjuster nuts are steel, and the pinion pilot bearing has been reinforced with superior D-4512 nodular and additional material. Bearing bores and reinforcing ribs are cast with additional D-4512 in critical areas; ribs were also carefully designed to further enhance rigidity. Machined by the same company that SVO Ford chose to manufacture all its 9'' cases: Strange Engineering. Nodular cases are nearly indestructible so they're recommended for any vehicle that accepts a 9'' housing and 9'' gear set.
