Rear axle pair with 300M bolt-on inner stubs for the 2004-2006 Pontiac GTO, rated to 1400HP. Thicker 108mm Porsche-style CV joints with 4340 cages replace the factory joint design, and the 1-1/4 in OD 30-spline bars are a modified 300M with rolled rather than cut splines, which keeps the grain structure intact for higher torsional strength.
