regear from 3.73 to 4.10?

hey guys I have a 2002 3.0 edge with 3.73 7.5 and 33" tires, I am wondering if I should buy 4.10 gears or 4.56 gears and if so would they fit in my stock axle?


note:I am not that interested in getting an 8.8 because I do not plan on going offroading, also most driving is in the city

Just buy an 8.8 from a junkyard with 4.10's in it. assuming your truck's a 2wd it should be relatively cheap

IMO...get yourself a 4.10 axle instead of getting new gears and getting them installed. You'd spend about $200 for a junkyard axle and you'd maybe be upgrading to an 8.8" rear end compared to a smaller weaker 7.5" rear.....plus you might be getting a limited slip if you're open right now. IF you decided to get 4.11 Yukons, it'd run you about $200-250 for just the gears and approx $200-500 for install. Add alot more if you are 4x4. I'm assuming you're a 2wd. In my opinion, 4.56 is too low of a ratio for 33's and the 3.0L...unless you plan on upgrading to a larger size down the road. BUT i will also say, a lower ratio = better in city mpg and funner to drive...but rpms are pretty high when on the freeway, resulting in more fuel consumption.

I would look into just swapping in a junk yard axle that has 4.10 gears. Much cheaper and it will bolt right in. You can get an 8.8 28 spline, they are behind 4.0 rangers.


Jesus I am slow. EVERYONE beat me to it

I got 4.56 on my 2.3l with 32s, and it almost feels like it is at stock again, tad bit higher RPM but perfect feeling (and again, very close feeling to stock just a tad more pep which is great since I live in a hilly area). I average 25-26 mpg (max 28 mpg) 50/50 mixed highway/city. FWIW!

I was wondering on the weight smarty pants. If its a 10.50 he might be able to get away fine with 4.10.

Weight will be negligible, like 1 pound or so, not enough to justify going from a 4.10 to 4.56, smarty pants

It's tire diameter that matters there smarty smart pants.

Do you really want me to pull out the math equasions?

Im not saying it doesnt matter I know it matters. Just a wider tire weights more. Its science. Pull them out if you'd like ive never sat down and done the math how much lighter they are.

I would go with the 4.56's. If not 4.88's just incase you ever want to do a little bit taller tire.

EXCUSE ME....TIRE DIAMETER is what you use in order to determine proper gear ratio. Tire width has NOTHING to do with it whatsoever. Say he's going from a (assuming he's a 4x4 edge) 245/75r16(30.5") to a 33" tire, that's 10% difference in diameter. 3.73 x 1.10 = 4.103....he's fine with 4.10s for a stock like feel.

If you're considering unsprung weight in this, assuming the added width of a 12.50 tire makes a differnce, how come you havn't asked if he's running steel wheels or alloys???

You are all wrong and right. A wider tire will weigh more, and weight is a factor in gearing as the more it weighs the harder it is to start to turn it. Now the weight difference between a 10.5 and 12.5 tire is negligable. There is not enough difference to factor it in so in turn the diameter is the only dimension we worry about. so you were both right.

It was just a pun on an Animal Farm line.

I see this thread has been 'cleaned up'. Disappointed indeed.
