Unless you did them yourself(and even so) that's ******* retarded....I bet you probably spent about $500 getting those. All for about 1 mpg difference between 3.73's and 4.10's. Even if you have a 2 mpg difference and got 15 highway you'd only be saving about $9 every tank of gas. That means you're gonna have to drive about 25k miles JUST TO BREAK EVEN.

That's stupid man.

I would say get a soft tonneau to save 1 mpg.... much cheaper, or even a plywood one for less than $20 lol

Does it really feel like you've lost a bunch of power? I was actually looking to do the same thing, but not if it's going to feel like **** leaving each stop sign/street light.

I also sit at roughly 2500 @ 80... and before I was at 2100 @ 80

That's impossible. You must of accidently set the 3.73s you took out next to the 4.10s and put the 73s back in.... straight up
