I'm really new to Dodge/MOPAR stuff. Can you expand a bit on what you bought, what was needed to swap and how involved the install was? Thanks from a newbie.
No, this will only fit the 2015 and up cars. What you want is one with the limited slip (2 wheels spin instead of just one). It's most likely my next modGood info! Is that the rear end from the Mopar 11's?
Yes my understanding is that it’s ‘15 and up only. I had access to a lift, but we probably had it done in about an hour and a half.No, this will only fit the 2015 and up cars. What you want is one with the limited slip (2 wheels spin instead of just one). It's most likely my next mod
The NAG1 with a 3.90 rear axle ratio gives you an overall first gear ratio of 14.00:1. That is less torque multiplication than the 8 speed with the Scat Pack/SRT standard 3.09, which has a 14.55:1 overall first gear ratio. So the 3.90 swap seems reasonable to me for the NAG1. Had I driven a Scat Pack or SRT with a 3.09 while I still owned my 2012 R/T, I would have done the 3.90 swap myself. But my 2012 was totaled and I wound up getting a Scat Pack!I did some calculations and a 5 speed NAG1 automatic with a 3.59 1st gear and a 3.90 rear ratio would be equivalent in first gear to a classic Mopar muscle car with a 4 speed and a 5.28 rear end ratio. You will get no traction in first gear and it will shift into 2nd pretty quickly. Drag radials will be a must!
You can get the 3.07 with the super track pack option in the R/T Road and Track or R/T Plus but the STP option is not available with the R/T Max.Too bad Dodge doesn't offer the 3.09 with the 5.7L/8 speed that would have been a nice combination.
I was going to be kind of shocked if you didn't have to do something. It would be nice though.I have decided to go get the pcm calibrated to the correct ratio. I still have no lights, etc. There have been a couple occurrences of the car bouncing off the rev limiter before shifting and super hard/awkward/ill timed downshifts. I’ll update once I see how the calibration goes.
Initially, on the 2015 they did offer the 3.09 on the Road and Track package for the R/T, but at some point the 3.09 option disappeared. It is not even available on the Daytona 5.7 now.You can get the 3.07 with the super track pack option in the R/T Road and Track or R/T Plus but the STP option is not available with the R/T Max.
