S-Series Nodular Iron Third Member with Differential, and 1350 Series Yoke.

Strange’s radial rib design significantly increases the rigidity of the case Strange Engineering’s own blend of nodular iron contains more bonding additive which increases material strength by 8-10%. Coupled with strategical reinforcements to the pinion support area, tail bearing pocket, and main caps, it exceeds the strength of the factory nodular case.

The 3.062” bore case will fit all differentials and spools from 28 to 33 spline. The 3.250” will fit 35 spline differentials and spools, and 40 spline spools requiring a 3.250” bore case. The pricing allows an individual to purchase a new upscale case at a price of a used and fatigued factory part.
