This durable Chevy 12-bolt rear end package includes leaf spring mounts.
 
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. 
 
This rear comes with Wilwood disc brakes and axles installed on the housing.
