The 2010 DP are all 6.1. Same car as 2009. I think you get a boat trailer rear axle to go with the boat trailer tires. So you don't have to throw away the piece that came with the 09's. You want one, all you have to do is call. My completed car weights 3040 without the slightly overweight driver. I used a Mopar 8 3/4 axle, the Dana 60 is heavier. The Hemi motors are a little heavier (I think) than what I used. Email
