Challenger R/T Differential

[wephillips]

Hey everyone I am looking to change out the stock 3.06 gears in my chally, however, I cannot find anything to tell me wether I have the 210mm housing or the 215mm housing. Dodge cannot even tell me! HELP!!!!!!!

Thanks Willus

My 09 RT auto had a 215 mm. I just changed it to the Getrag 226mm. To my knowledge no challengers had the 210 mm rear.

You both have 09's and your stock set up is a 215mm 3.06? I'm getting ready to install a 3.73 LSD Getrag in an 08 Chally SRT8! Just wondering what are the options for factory rears.

Factory rear gear options are: 3.06, 3.73, 3.92. All auto's come with 3.06's.
