Strange 12 Bolt Rear End with Pro Race Axles, Spool & 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 manufactured using chrome moly material 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.

Pro Race Hy-Tuf axles

Strange also offer high horse power drag race applications with Hy-Tuf axles that are forged from Hy-Tuf steel that was originally developed for highly stressed landing gear in military aircraft. The material is in the class of Ultra Strength alloys and contains low carbon, high manganese, high nickel, and high molybdenum steel. Pro racing axles are thru-hardened allowing for a Drag Racing shaft with an exceptionally high, 240,000 PSI, tensile strength while retaining ductility.
