All v6 carriers are 198mm. Have them check the sticker, which is on the topside of the diff. If its not out of the car use an inspection mirror. Looks at the pics on page 1 and you will see where it says 3.64. When I picked up my dads the one they tore out had 2.87 so I told them to check with the mirror first and they found a 3.64

That sucks because those are the only two close by.

as PRPLHAZE said, all V6 models use the 198mm ('05-'10).
all 3.5L 4 speed have the 3.64.
3.5L 4 speed was available in 2005, early production 2006 and all 2008-2010.

that being said, if the 2008 is a 3.5L, then the rear diff is 3.64.

Yep all 3.5 cars with a 4spd transmission had the 3.64. I'm glad to see something about my car is desirable. I just wish I had the 5spd. My 1st gear is too high and too much difference between 1st and 2nd cus once it shifts if you get over 30mph it wont down shift at WOT and it feels like it's pulling another car behind at 35 till it gets to maybe 3500 rpm. The 5spd is much closer ratio between gears and makes better use of the power the 3.5 can develope.


(Wishing for a 5spd.)

I think i just screwed myself guys i just picked up the carrier..i havent had it installed yet but the problem is my predator whatever crom it is doesnt have 3.64s as an option. I contacted johan he doesnt know when he would be able to get to it. I dont know what the hell to do now. I feel like i could have waited if I cannot use it no time soon :(

[dejuan71]

What crom did you guys use??? Johan still has the croms

[nyxis]

Is there another ratio that is close to 3.64 in your predator?

Anybody had luck finding a 290.00

So ur saying I have this in my magnum already? Or I need to get this to improve my torque? I have a 2.7L 08 magnum. I wanna get off the line quicker and be able to chirp tires.

your 2.7L is equipped with 3.90:1 gears. not sure if any higher ratios are available for the 198mm axle.

[dejuan71]

I updated to the latest crom with my tune saved to my computer so everything is working good now.

So are u saying I need bigger axles?

i don't think there are any aftermarket gear sets offered for the 198mm axle. if you want higher ratio, you'll need to go to a different axle or shorter tires. even so, i don't think there is tuning available to adjust for the different gearing. at least not for the 2.7L.
