DriveShaft CH9R-4 Automatic 9'' Rear Conversion Kit 09-11 Dodge LC Challenger SRT-8

The Driveshaft Shop SRT8 9" Rear Conversion is now a reality. We borrowed our good friend George Kooks' 300C SRT8 for the prototype and we're happy to say the kit is now ready!!!!

The kit will come complete with 9" rear housing (bare housing), front mount, rear weld in mount, custom 1400HP rated 31 spline diff stubs and true 1400HP axles that do not use any “Factory”or "used parts". The outer CV is a Extreme built Billet CV with fully REM polished internals along with a Porsche style 930 inner CV. We have custom made the internals of these CV's to use the larger center bar that is the strongest tested part on the market today.

This, along with our full 3" 1350 series 2-piece drive shaft (not the smaller 1330 that is offered by a competition rear conversion), balanced on our new 9500RPM balancer. A quick word about balancing; we have recently taken delivery of our new custom made balancer. Most balancing machines can only spin a shaft from 400RPM-3000RPM, although these are good machines, they do not see the unique problems that the modern muscle car presents. These newer cars are uni-body and have most of the components bolted directly to the floor, so a real high speed balance is needed. We guarantee that this shaft will not vibrate at any speed.

The installation of the kit will require a slight modification to the back of the rear cradle, a template will included to put on the frame to show where alterations need to be done (it is not a difficult modification, but it should be done by a professional, see pictures for this job). We have decided not to supply the kit with the center section, due to the large variety of gears and differential choices, we have decided to let you pick exactly what will work best for your needs. The rear bolts right on and it will be the last rear you will ever need for the car (unless you want different gears for different tracks).

Note: CH9R-4 - 09-11 LC Auto does not includes hubs.
