Rear axle ratios

So somehow I missed the boat on the Ram -- I didn't realize the Hemi came standard with 3.21 gears on most trims. I had been looking at the Tradesman Crew Cab 6'4" box model, which according to build and price comes standard with 3.55 gears like the Ecodiesel (that configuration also comes standard with the Hemi unlike most). But so far I haven't been able to find a window sticker for one of those to verify; only diesels. I see that the 6-speed transmission comes with 3.55 gears, which is the standard on that configuration, and it doesn't even give the 3.21 option when you specify the 8-speed, but I wonder if that's an error. Ram window stickers stupidly do not list the wheelbase or bed length so you have no idea what it is.

At any rate, that puts the normal Hemi's net first gear ratio at 15.13, more in line with other brands, and the difference between standard gears and the upgraded ones a whopping 22%.
