I'm pretty sure that the rims have a +42 offset and the 20 is 9" wide. The 17 may be only 8 but it's likely 9. If you take off a wheel it should show all of the dimensional Info cast inside the rim
But the updated oil is followed by a ECM&TCM flash to keep everything functioning to mopar spec but the flash is only available for the 2016 model year as of now. The 14&15 do not have flashes available yet
If you check out the link I have in the air suspension lift thread they also offer lowering adjustable links so if you've got factory air suspension it'd be very easy as long as you stay within alignments capabilities.
22x14's and 36's are going to need more than your traditional lift kit. And with air suspension no less? Idk how it's going to work out.. need some seriously offset rims. A 6" lift that they don't make for the air suspension and then the rest of the factory suspension isn't going to be able to...
You want to go from the factory 9" wide wheel to a 14" wheel? I guess it'd all depend on offset. But that's a lot of meat to be turning.
And I've got no idea what size tire you plan on running...
And the wifes been out of work for a while pregnant. And now will be for 2 or 3 more months. And is going back to school.
The list goes on and on.
Not entirely decided yet but I'm considering it more than I'd like to admit
Some are just kinda bad apples from what I can tell. Mechanically mine has been flawless for 32,000 miles. Only had a water leak from a pinched sunroof drain and that's it.
Aside from the black exterior and 6.5' box I could've sold you mine and it'd be loaded to match your hemi (maybe a little more). ;) air suspension, sunroof, HID lights, cattle tan leather.
Yeah it's something new. Both Def and diesel to fill up there but you always have to prepay. Except there's one very small truck stop in erskine Mn (middle of nowhere) that has Def on tap that you can just pump away then go in and pay.
