    Question Differential Swap

    I was wondering what is required to swap my 2.65 differential for a 3.06? I've been doing a lot of research on various forums, I managed to get some info, but I am not mechanically inclined, so I'm kind of confused right now.

    My car is a 2010 Charger R/T Road & Track, donor car is a 2006 Chrysler 300 SRT8.

    Is it "plug and play" or do I need other parts?

    I have done install twice on pre eagle Hemi cars. You will feel the difference but in the end it is still an open Diff but for sure tougher. I know on the earlier cars you need to trim the parking brake tab slightly for the beefier shaft from the SRT. One question is are the 2010 hubs the same as the earlier 5.7, 6.1 cars if so you are ok there. You will also need the rear 4 prong driveshaft and coupler from that car as you likely have a three prong and does that piece mate ok with the 2010 front piece you have. I ran one until I could find a good deal on a Getrag setup which you may want to consider as your traction will be night and day. Danny

    You need the diff and the back half of the driveshaft, unless you want want to swap the 3 prong pinion from your diff to the old one.

    For cost saving vs capability a Getrag swap would be better. Then you don't need the driveshaft half (and has LSD). I initially put in a same year SRT rear, snapped axles. Found a deal on a Getrag and it's been awesome since.

    A Getrag would be great indeed but I'm on a pretty tight budget. In fact, I had no plans on swapping the diff but I found one for cheap so I just want to make sure that this cheap mod doesn't get expensive with all the extra parts that I need. I can get the diff, axles and drive shaft for $300.
