February 17, 2006im getting 37" tires and im going to run 3.73 until i can afford 4.56's and i got a 5.4 L Why do you need 4.88? Check the numbers 4.88 puts your at more like a 4.10 ratio.
I checked mine and 4.56 puts me a little over a 3.73 ratio... about 3.82 to be exact....
im getting the 4.56
if your going to get 4.88's then just do it and quit playing games.. you wont hurt anything.
The revs might be higher on the highway but if youre not doing 90 then it aint a problem
