The performance of this p. U. W 3:92 axle is almost unbelievable. Ride is very gd and the truck is quieter than the ram I traded. This is my 6th ram and everyone was excellent. No Major problems with any. 2009 is the best yet. A friend has a hemi w/vvt etc. And claims 19 mpg to and from work. Wld rec. This pick-up to any and all. Don't forget lifetime drivetrain warranty.
