3.92 in 6speed???

[Welderwilly85]

Anyone ever see a 5.7 6speed with 3.92 gears? Maybe I’m missing something here???

There were plenty of 6 speeds with 3.92s

When I run my vin it always shows it being a 3.55 so it’s just weird

Everyday when I get in my truck.

Yep, had one in the ill-fated 2013 Laramie.

Explains my less than awesome interstate mpg

Pulls good though right? Most of us HD guys want 4.10 or lower.

I had 3.92’s in my 2011 CCSB 4X4 HEMI.

My 2012 had that combo.......

I have it now in my 2017 cc sxt. I've been hauling my 33 foot TT loaded to 8400 lbs. Tows well when properly loaded.

My 8 sp with 3.21 tows around 7500 to 8k every weekend no issues then when I'm not towing this happens. I'm actually very impressed with mileage even towing I'm at 11.8-12.5.

I get similar...21.4 mpg. Not bad for a crewcab 4x4.

My 2012 outdoorsman has that combination, interstate mileage is't great but it tows my camper very well.

I get about 18mpg on the highway. Could be better...but in fairness...could be much worse.

That’s about the best I get also!

I have a 2017 CC 4x4 SXT with the 5.7 Hemi, 6 speed and 3.92 rear end. Pulls great. Even got the factory air suspension installed. I get ~ 13.5L/100 (21MPG) Highway and 23L/100 or worse (12MPG and down) depending on when I'm towing. 31 foot TT, approx. 7500-8000lbs loaded.

Where would I find this tag? I would love to know my ratio!

 

[Rammer2109]

I just towed our 34 foot, 8500 pound TT from NS to Alberta, 6000kms. I got 24L to 30.5L in the mountains. But I myst say it hauls well at 90km/h.
