Which rear end???
1 - 14 of 14 Posts
I researched* this quite a bit on f150forum looking for verification that all 9.75 rear ends are 3.73/1 and all 3.73/1 are 9.75 and I could not find a counter example for the gas engines. Each time I build a truck with a 3.0 on Ford.com I cannot chose 3.73 ratio; if the data for the gassers hold, then all diesel engines have an 8.8 inch rear end.
*by research I mean I solicited input from the forum crowd. I read the sales guides too, but couldn't find a black and white answer, thus all that I have is anecdotal.

I doubt the 3.0 comes with anything but the 9.75, but be sure to ask dealer!
Hello,
Slightly hijacking this thread I suppose, but it is a similar topic.
I'm trying to decide on a gear ratio, and since I won't be able to test drive each under various conditions (towing, highway cruising, etc.) I am wondering if there is a consensus on which one is best. The most I will pull is 7500 lbs. and I am fine with locking out 10th or 9th if I need to, or if the transmission moves around a bit under that kind of a load, however, when not pulling I would prefer the truck hold in 10th as much as possible on the highway. I rarely go faster than 70, but don't want to have the engine at faster than needed on the highway, either.
Basically would either ratio serve me fine, or if I were to err to one side or the other, which one should it be?
I am leaning towards the 3.55 but I am coming from V8s where the revs were more beneficial.
Thanks,

Get 3.55 hand down, no questions asked. I wish I did. I dont tow, but I want it sometimes on the freeway.
Thanks,
Are you saying that at highway speeds the transmission will shift down to 9th on inclines etc.? I am assuming (but don't know) that first is plenty low, especially for this motor, when starting from a stop, towing or not. But, again, no firsthand experience.

I have 3.31s and 35s and yes it does, even did it before I put bigger tires on. Its really not a big deal it down shifts as its still locked in OD, but its more the fact you are loosing speed to other drivers and have to give it a little pedal to kick down and go.
Dude you have ZERO to worry about from a stop, SOOOO much Torque. Its keeping it going thats the problem for this 3.0.
Get the 3.55s.
