Another part of the discussion...

Posted by: jimh
Do the manual trans Challengers have stronger half shafts than we have now? Since it's pretty much a shortened LX will the Challenger half shafts fit on a Charger, or does the new rear change too much?
Thanks guys

Posted By: Team SRT

The whole rear end got an upgrade for 2009 to handle the increased torque requirements of the manual trans. The halfshafts went from 28 to 32 splines. The axle got bigger (and got a real LSD). The driveshaft coupling got beefed up too. These upgrades are on all Challengers, 300s and Chargers starting in 2009 model year.
So when we break do we just need to upgrade to the 2009 LSD..??
(realizing it is clearly not just that simple...)

And you should be under warranty anyway ... i'm sure this isn't a known problem because if a lot of people have the same issue i'm sure dodge would do something...

Do you have a preadator or any other mods ? Or are you completley stock?
I have the Mopar CAI, 40 series Flowmasters, and had the predator. Out of curiosity, I restored my original backup from the tuner several weeks ago to see if my gas mileage was any different without it. MPG was higher with the predator and the 93 ocatane CAI canned tune.

I will be pressing them to upgrade mine to the 09 rear end. The more I think about this, the madder I get.

Why would the manual need a beefier rear than an automatic?

Parasitic loss through the torque converter of the stock transmission delivers about 10% less HP/Torque to the rear wheels than it"s manual counterpart...

right Andre...??
