I'm going 4.88's in the next month or so. I'm leaning towards the 36 13.50 iroks

 

i wouldnt go up to a 4.88 with only 36's. stick with a 4.56

 

I do tow on occasion and it's generally around 5k that's why I was going up that high. Silver said he wished he had gone to 4.88's

 

Ya I would go with 4.88's

 

dont plan on going any faster than about 60-65.....and when your at those speeds....you'll be pulling 3 grand or a shade higher......and nevermind when OD kicks off.....

 

itll be that bad?

 

My truck has 36.5" tires and 4.56 gears. At 70mph in OD, it is running right at about 2,200 rpms. I am glad I didn't go with the 4.88's because it would be running even higher than that on the interstate.

Also, you can see from my sig-pic what 8" of total lift looks like with 36.5" tires. I thought I had a 6" susp lift with 3" body, but I found out it is really only 5" susp lift, so total is 8". I would almost rather delete the body lift and drop to a 35" tire, but it would be money spent that I don't have, so I'm leaving it this way for now. These tires are a little too skinny for the lift in my opinion. I would rather they be another inch or two wider for the look I was after when I bought them.

 

well unless your truck has something special that my truck doesnt, im running about 3 grand at highway speeds. its a love hate relationship though bc shes got a $hit ton of low end power and takeoff.....but the highway rpm's and gas mileage kill me. im lucky to get 11-12 mpg on a nice long highway trip. not that i care.... if i wanted mpg's i woulda bought a prius lol

 

The biggest I'll run will be 36 so y'all think I should stick to a 4.56? I'm not really worried about gas mileage but I really don't want 10 to the gallon but I'll deal with it if need be.

 

yeah stick with a 456 if you will only be running 36's
