DriveShaft GM43 1000HP 300m Axle Kit W/108mm Bolt-On Inner Stubs 04-06 Pontiac GTO
Here is our newly redesigned 1000HP Axle / Inner Stub kit. This set of axles has the thicker Porsche style 108mm CV with full 4340 cage (not just chromoly ) internals that is significantly stronger than the factory design. These axles feature our new 1-1/8" OD 36 spline modified 300m bars (our 300m is made and certified to higher torsional standard than most 300m material).
Now you need to understand that our 300m skinny bar is smaller in diameter than the standard 28 spline that a 108mm CV would use. We have made this axle so its stronger than a regular 4340 bar, the real reason to doing this is its more torsional during shock loading, using this 300m skinny bar with the 300m stubs will allow a mid-Hp to high-HP car to have a great set of inexpensive axles that will torsionally twist at the axle more freely and save the Diff from being hurt. the stress created at the back of the spline it stronger due to the fact that the spline is rolled (material is compressed making it a forging) by not taking grain structure away e have found this to be the best combination for the stock diff with 28 splines.
