Pulled this out of my 2010 Laramie (at 4K miles), and added a 3.92 since I tow quite a bit. With the 3.21, I got excellent gas mileage - going from Atlanta to Orlando on one tank (511 miles, 23.1 gallons) and averaged 22.7 mpg on the way back doing 69-72 mph.

When I dont tow, I miss these gears. A lot. Selling for $200 shipped.

 

i think its very expensive . can you give it for $160

 

Where are you located?
