I love my 4.10's. Wish I had done them sooner.

 

4.10 without a doubt.

 

I love my 4.10's on my '06 auto. My MPG is still the same, I get avg. 18.5 mixed driving. I love the feeling of the better delivery of torque and you just leave everyone else behind you at the stop light, and that's not even with aggressive driving. One of the best mods ever. Just make sure to get the FRPP "A" gear set and a good installer. Gear whine will just ruin your days to no end.
