Possible tow rig. Suggestions?

[Chadnutz]

Was 3.55 not a factory option?

Wouldn't that be the same difference from 4th to 5th gear?

Maybe it has power in 4th, but not so much turbo in 5th?

It screams in OD at 70 mph. Something like 2400 rpms. I didn't
check wat RPMs it was at in 4th at that speed.

3.73 was factory... 3.55's may have been but damn that's high... leave the 4.10's you'll like them when towing... Also your RPM's will come WAY down if you put some REAL tires on there.

I turn 2500 RPM's at about 80-85 (My speedo is off).


My turbo only starts working well around 2100-2200 RPM. and you'll need to maintain that RPM for at least 10 seconds to allow the turbo time to spool up.

It is mine.

welcome to Ford ownership. hope you've rebuilt that tool collection.

[Chadnutz]

I haven't, but I convinced my bosses to let me buy a 251 piece Craftsman set. Why should I buy tools when I can use work tools? $$

welcome to the wonderful world of ford. where no care is taken to segregate between standard and metric on any given part. and sometimes you even get to venture to the fantasy land of what ****ing size is this because the geniuses somehow managed to to create a bolt head that is neither standard or metric... I think it's called vise grip size. and the best part is all the extra nuts, bolts and washers they hide in various places so they secretly appear when you take something apart. that way in case you misplace one of the original pieces you have extras. at first I thought I was forgetting to put some of these things back on. I was later enlightened to the wise ways of ford manufacturers...

3.73 was NOT offered factory in that truck. If it screams (2400 rpm) at 70, you've got 4.10. 4th gear would be 3000 rpm. The only other ratio offered was 3.55.

Average mpg:

88 - 98 had options of 3.55 or 4.10 only

94 F-350 2wd CC 33s 4.10 - 14 mpg
94 F-350 2wd CC 33s 3.55 - 17 mpg
94 F-350 4wd CC 285s 4.10 - 16 mpg
same with 35s 16.5 mpg
97 F-250 4wd XC 285s 4.10 - 12 mpg

99 and up have options of 3.73 or 4.10 only, and higher overdrive

99 F-250 4wd CC 315s 3.73 - 16 mpg
99 F-250 4wd XC 315s 3.73 auto - 15 mpg
00 F-350 dually 4wd CC 255s 3.73 - 14 mpg
02 F-350 dually 4wd XC 235s 4.10 - 13 mpg
00 Excursion 2wd 265s 3.73 auto - 17 mpg

Dodge 2500 4wd XC 35s 3.55 auto - 17.3 mpg


35" tires will make your 4.10 gears the equivalent of 3.73 with stock tires. I think that's perfect for that truck. 37s are cheaper. Like Doug said, it needs to spin about 2200 rpm to make power.

You won't "need" a power chip untill you ride in a truck with one. Want to? You'll never beat my Dodge.

get ready for the oil pan gasket to start leaking.

...and rear main.

I don't want 35s.

[Krawler68]

no he's always been the guy who wants the smallest tires possible...secretly i've wondered why he didn't just join "Lowered Expectations" or some other low rider club... he drives a mazda and has parnelli Jones tires...I think he'd fit in...


That powerjokeneeds at least 35's and a set of 16.5x10" rims...
to clear that boat anchor front and rear axle combo and give it a more stable stance.

The only real input i have here is on the add a leaves. I have the type that arch, not the flat ones, and i hate them. The ride sucks worse than stock unless I have a REALLY heavy load in the bed. I just can't imagine having then in the front and riding rougher than it is already. If you are going with the flat ones then ignore all this.

I said that not knowing how tall the tires are that are on it right now. I guess they are about 33s and I said I wanted bigger than 33s, so hell, I guess that means 35s.

Anyone know how tall 265 R16s are?

[Seth]

you have to have the aspest ratio number as well to fig out the height -- so are they 75 or 85??
