Welcome to the forum Patrick. What gear does your Charger currently have, and what are you hoping to accomplish with the change? Common upgrades from the oem 2.62 or 3.06 are 3.70 or 3.92. I am not aware of a 3.55 gear for the Chargers.
Good morning Patrick:
Being an '07, your Charger has the NAG1 5 speed trans. If you do much highway driving, going to 3.92 is going to put your highway rpms up there quite a bit more than you are used to. The change in acceleration though will be night and day from your stock gear. If your focus is mainly around town, stop light to stop light, etc, then the 3.92 would be a good. OTOH, if you spend time on the highway on a regular basis, then the 3.70 would be a better choice. The rpms on the highway won't be quite as high, but the improvement over stock will still be very worth it. In addition, I believe you will need a programmer to reset the computer to the new ratio so your speedometer reads correctly.
Why are you making multiple posts on the same topic? This is the 3rd separate post you have created now for the same questions. To do this is considered bad forum decorum.
I answered these same questions in your original posts.
You sir, are the DH! I have replied to your posts with helpful information, and you thank me with such comments. Keep it up, and you will find yourself banned from the forum.
I am done with your high school nonsense.
Not the best way to get people to help you with things you don't know, especially since I'd be willing to bet real money you only joined for this one question and we'll never see your fruity ass again lol (at this point not a big loss, but still lol).
Hey all! I have a 2011 charger pursuit v6. I have a goal of eventually being able to reach the end of the 260kmh speedometer. The hemi version has a listed top speed of pretty much that exactly. So I figure I should only need another 100hp or so. Is this plausible to do without nitro or...
I have a 2012 3.6vvt charger with a complete factory exhaust but I would love for it to sound like the 5.7 hemi with the mid muffler delete. Is this possible? If so how and if not, what can I do to get as close as possible?
Had semi performance mufflers on my 2014 Charger SRT and no resonators. Recently I had Powersticks installed and these are very close to straight through pipes. I'm now noticing that the MDS (switching to 4 cylinders) almost never comes on. The only time I'm noticing it turning on is when I'm...
I have an 09 dodge charger pursuitAnd I’m thinking about fitting 11 x 18 demon wheels I know everybody’s gonna look at me weird but i’m just curious if anybody has done it and what modifications would have to be done The square set up in My opinion looks really nice
