04-07 CTS-V Partial 8.8 Kit is offered for the do-it-yourselfer that wants to supply the differential center section on their own.
NO modifications to frame but you will need to change to 31 spline carrier, ring and pinion and pinion flange.
Kit includes:
- Powder Coated mounting brackets to mount the Ford 8.8 housing to the original mounting locations of the factory differential with hardware.
- Bushings and 8.8 bushing block
- 8.8 adapter (use your OEM drive shaft or DSS replacement shaft)
- DSS axles – 31 spline inner stubs to mate to an 8.8 rear differential equipped with a 31 spline carrier. Rated at 1000hp (ask for a quote on higher HP rating if needed)
Be aware that modifications to the 8.8 rear cover will be required to fit our brackets, which will include the grinding and welding of aluminum.
Paul –
Very nicely made parts. I did the partial axles, my own back cover and stock driveshaft adapter. Make sure you cut the mounting tab on the back cover low enough before getting a plate welded on. Don’t ask me how I know. The CV joints were a little tough for me to get back together (first time rebuilding one). I had to massage the subframe on the drivers side to get the axle to slide in as the inner CV joint hit it. But once in place there was plenty of clearance. You’ll also have to massage the drivers side exhaust and/or grind down a tab on the diff for clearance. But what a difference. No more whine or clunking.
