Description

Strange Street 12 Bolt Rear End With Heavy Duty Posi & Leaf Spring Mounts

This durable Chevy 12-bolt rear end package includes leaf spring mounts.

This Strange GM 12-bolt rear end is available with your choice of housing ends and custom widths.

The Strange 12 bolt casting is much stronger than the OEM 12 bolt, while still accepting the same components. The casting is poured from proprietary nodular iron which is substantially stronger than cast iron. The main caps are constructed from forged chrome moly, instead of cast iron like the originals. These improvements in materials, have allowed the casting to be made not only thinner and lighter, but also stronger. The casting has a torque arm mount cast as part of the case and a location for a Strange 3 channel sensor.
