DriveShaft GM9R-4 9'' Independent Rear Conversion Kit 04-06 Pontiac GTO

This kit is fully built to withstand the most punishing setups and keep going without a whimper. In addition to the 9” housing, brackets and hardware, we are also including our signature 1400HP Pro-Level axles with the uber-strong 30 spline center bars. These axles are without a doubt the strongest on the market, with 300M Races and full billet 4340 CV cages. The billet axle stubs going into the differential are also included and are 31 spline to fit many of the popular center sections. We have been asked why we don’t use a larger spline into the differential, and to be quite honest, anything larger than the axle center bar is not going to make it any stronger (we use a 30 spline center bar, unlike the standard 28 spline that most 108mm CV’s use). This design is the same as can be found on Lingenfelter’s 2010 Camaro 6 speed manual running 8.99′s at 4200lbs along with Mark Carlyle's ZO6 vetter (8.15) it is a testament to how strong they really are (not to mention Travis/Tbones killer GTO running 8.90’s with a trans brake).

The kit will come with a choice of a 4″ Aluminum shaft or, for a nominal upgrade fee, the new 3-3/4” Carbon Fiber shaft (using our new bonding technology). The shaft will also have a Strange billet transmission yoke of your choice and solid 1350 series u-joints. It will be balanced on our new true to speed 9500RPM balancer.
