Saw a 3.21 guy leaving the tire shop the other day pimping his new wheels and tires.

With these tires, the final drive should be 12433 to 1!

Ah, so this would almost make a 3.21 a real truck?

Way better than any 3.92 for sure.

Imagine 3.92 with tiniest tires, could tow a church, 2mpg!! 0-60 never!

Plus 10 gallons to the mile!

Was thinking of 105/ 75 r12 with a 3" spacer, anyone else? Any rub at full turn? although it is still better than 'the Carolina squat'

Well it has been a while. I guess the 3.21 crowd had conceded that thier choice of an inferior gear ratio was a mistake and have gone back to hiding. I haven't heard about the incredible milage of an extra 1mpg over a truck geared for the torque and power of a 5.7 Hemi motor.

Go.

I’m still here! Avg mpg 42.7

I got ya. Just hauling air in the bed, corn squeezins might be a bit heavy. I guess as long as you stick to the flat lands those 3.21 gears will eventually move you on down the road!

I just got back here. The 3.21 gives me much better mileage, but it does take a bit longer to get from A to B, since it's so slow off the start.

But the other issue? My 3.21 gives me so much better mileage, it's making me fuel. Seriously, I only fill to halfway. Then, when I get home, the tank is almost full. I've got to be careful in the turns not to slosh it out.

3.92
Just another great idea

Leave it to a 3.21 'guy' to be thinking about my junk. Gross dude

Lol, you've missed a lot of the 3.92 guys comments then. 3.92 makes me a man instead of those girly 3.21 gears (insert tim allen arr arr arr).
Lol, 3.92 medium guys

I’m running up and down hills, hollows or “hollars“ when pronounced correctly. And haul *** down the interstate quite often. She doesn’t have issues. BTW, I’m good for a jug.

3.92s are good for overcompensating for small manhood

That's one of the best 3.21 tales yet! Beats the heck out of Prius milage!

Why does this seem like it needs a "well your mom's tonsils..." reply.
