No engine tuners for the 2011's

 

If you're going to stay with 35s and not go bigger go with the 4.88

People will say go with 5.13 just becasue its a higher ratio but it could also hurt your motor...

If you dont drive it daily , get the 5.13 . if you do drive daily, go with 4.88

 

have the same 2dr auto 35" setup and I did it this way, its my daily driver.


the 5.13 pinion for the d30 is really small and you can find many posts with broken dent histories, i went with strength over power so... no front blocker for me ever !

 

I've got 5.13 in mine and its a daily driver. Works great. No problems on road or off. 3.8 auto with 35's and 3.5" lift. Look at the gearing sheets WoL has posted in one of the stickies. It will answer all of your questions. It's a big spread sheet that shows optimal gearing for varying other factors.

 

5.13 on Auto. 4.88 on 6 speed

 

What if you want to run 37's with 6 speed ?

 

Again, read the Sticky entitled "Modified Tech FAQ: Questions Every Newbie Has." It gives great charts for you to look at for yourself.

 

If you drive on hwy alot 5.13 will kill you on revs LOL very high

I have 4.88 6speed and 35s kills me on HWY wish i done 4.56 just a lil lower than 4.88
