    I have a 3.91 getrag rear diff. Was going to use it in my 300c but the gearing is too steep for the highway driving I do. Looking to sell or trade. I’m not even sure what these are worth anymore due to the popularity of swapping the 15+ cradles.

    I have been considering going from an open 3.06 to a Getrag 3.06 but am not sure its a necessity in my case as much as an obsession or for bragging rights.

  6. Transmissions Gears & Diffs
    Hello everybody! I've been learning a lot about the rear differentials in the the first gen LX cars. I see the more popular option to get a stronger differential with limited slip and better gearing is to swap to the 2009-2014 Getrag differentials. I didn't know until earlier today that they...

    Hi, looking to upgrade my 2006 300 SRT8 to a getrag rear. Will this handle 500 rwhp? Are upgrading axles a must or the stock ones hang in there? I know anything will break if pushed just looking for personal experiences of everybody. Thanks!

    Does anyone know the order of clutches and discs in the diff of the Getrag. The clutches came out with two steels back to back opposite Bellevue spring. I think the diff has never been apart. Waiting on Vette clutch pack to come in.

    I have a GETRAG 3.06 LSD that I would like to trade for a GETRAG 3.92 differential. Mine has around 80K miles on it. It is in very good shape other than the vent cap is a little out of shape. No biggie. I replaced both axle seals when I installed it in my 300C last fall. I no longer have to rely...

    About 6 months ago when I was searching the forums for my transmission problem I came across a post that had a master list of getrag cars. It included what cars came with what gear ratios. Which cars had the axles you need. All broken down by year, manual/auto, and model It was a VERY...

    looking to do a getrag swap in my 2006 300 srt8 with a used differential. I had been searching using the challenger srt8 2010, but have found more 2011-2014 challenger srt8 carriers.
