S-Series Nodular Iron Third Member with Spool, 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, including our 40 spline D2000 spool. The pricing allows an individual to purchase a new upscale case at a price of a used and fatigued factory part.

Ford 9 inch Spool

The Strange Steel Spool is forged in the USA from premium 8620 steel.

Strange 1350 Series Yoke

The Strange S-Series Pinion Yoke is fully heat treated for maximum tensile strength. Made from top-tier nodular iron castings, this yoke is economical and strong. If you are building a street/strip car or a cruiser, certainly consider the Strange S-Series Yoke.
