It appears to be the SS/1LE aluminum case with different limited-slip internals and cooling. Not the cast iron ZL1 case.

"Power is distributed to the rear wheels via a limited-slip differential featuring a helical gear set, rather than traditional clutch packs. The new design enables the driver to apply more power and get through corners faster, by continuously adjusting the torque bias to maximize available traction."
