I have an 8.8 rear end and I am wanting to beef it up and I need to know the ratio the ID tag says: s808d 3 55 88 8m22: so does that mean it has a 3.55 ratio?

I know mines a 3.08... Wish I had 3.55

1996 Redneck F150

I NEED 3.73s, but my 3.55s do damn good

i need a set of gears, i've got 3.55 limited slip in mine, but the spider gears are goin out or something and it doesn't work at all. i'm not sure what gears i need to go with, 4.88s or 4.56's

When you start making that big of a jump - you might need to check to see if you can still run the same housing with those ratios.

If you are going to be driving mostly under 55 mph those gear will get you there pretty quick, but not much more for extended periods of time. A 4.88 ratio with a 30 inch tire and 1:1 gear ratio would have the engine turning at 3800 rpms at 70 mph...Exxon would love you.
