has anybody put on a different gear ratio? I have a 3.55:1 on my truck, my brother just put on a 4.10:1 on his new GT, and another bro has a corvette with like a 2.30 something in it. has anybody put something else on their truck? how does it do?

I have Yukon 4.56's on my truck. I went with the new gears because when I lifted my truck and added the larger tires I lost some power. The custom tuning helped somewhat, but not enough so I added the new gears. Now my truck has all the power back and then some. Very happy with the gears.

4.56:1? that's a low gear man. did that KILL your gas consumption? also you must be running 3500-4000rpms on the highway right? my brother has a 4.10 on his mustang GT and said it cut his gas at least 3 mpg different

he has 35 inch tires, he needs the gear.

my 'bird has 3.73s, 3.55s are staying in my truck.

i know this. i'm just saying it must be a bitch to have that fuel economy. did it help your 0-60? or did the tires even it up?
