Hello,
I am checking in from CT. I have a Ram 2011 1500 4x4 Laramie with a 3.55 axel and no LSD. I want to convert to a 3.92 w/LSD. Does anyone know a good Differential Mechanic in CT?
Thank you.

It's going to be very expensive to do both sets of gears, I would just put an LSD in the back and call it good unless you want to lift it and run bigger tires. BUT....Laramie owners usually have a little more money than the rest of us
I reccommend the Detroit TrueTrac for the rear LSD

AND....welcome to the site! Great to have you!!!

Thanks for the info. Laramie is 2011 with 25000 miles. I got a great deal, so I may have less money than the rest of you.
I probably will go with the LSD only.

916Timmy,
Do you know whuch TrueTrac for the 2011 Ram 1500?

Not sure if they make one for the 2011 axle....I forgot you were a 2011. I think there is some extra work your axle needs to fit. I'll check!

Doesn't look like they make one for the new ZF axle you have, I know there was someone on here that did a gear swap and a new LSD, but it involved some machine work. The OEM LSD might be the best option for you.

I am going to check out more on the ZF rear ends too

On old AAM 9.25 differentials, you could just unbolt the ring gear from the carrier, easiest done when everything was taken from the center pumpkin, then you took out the pinion gear & changed it out, then put the carrier with the new ring gear back in, slid the axles back in & button everything up.

With the ZF 9.25 differential, the ring gear fastens to the carrier a different way, making the changing of the ring gear much harder.
It seems to me that buying a new carrier with the preferred ring already attached with LSD would be the simplest way to go. then sell the old carrier & ring gear, instead of paying for machining


Putting a locker in a chrysler product, very similar to our 9.25 AAM differentials
