I have a 93 F250 Extendcab xlt 4x4 7.3 non-turbo diesel e4od auto. I am planning on turboing it and adding a fifth wheel for towing, also a tranny cooler and some other mods.

I want to know what this truck can tow and payload weight cause Ican't find anything online.


Also is there anything I can do to the truck to inscrease my towing capacity on a fifth wheel trailer? Stronger axles, etc?

 

This is right from the Ford Recreational vehicle and trailer towing guide 1992-3....

The GCWR of the Fseries trucks towing a frame hitched trailer.

F series with 7.3 and automatic is:
355....12000lbs
410....17000lbs


F series with 7.3 and manual is:
355....12000lbs
410....14000lbs

whoa whoa whoa....theres a wheight limit besides when the tires blow or or the frame bends?....i would have liked to know this sooner...although i probly wont pay attention to it anyways -yes i have blown out a tire from overloading it before...its not my fault! that wood didn't seem that heavy!

 

The axles are just fine, thats one thing that needs nothing but good gear oil.

Think about putting a shift kit in the transmission, the extra torque will make it hard for the E4OD tranny to hold a shift without slipping. A electronic line pressure riser could also work if you don't want to drop the valve body, but a shift kit is best.

 

And watch out backing the trailer with a load. The reverse ciruit in the E4OD is woafully in adaquate for heavy use.

 

Wow this truck can tow that? I was thinking only 10k at most. I was thinking of spending an extra grand just to get a high performance tranny but I think getting a rebuilt stocker with a trans cooler and something like the banks transcommand? Does the Banks Transcommand still give me a reason to get a shift kit? Or would a shift kit with the transcommand be even better?

 

Before you get tooo excited, realize that these trucks empty, will full fuel tanks weigh around 7000 lbs, maybe more with the extenda cab!

 

GCWR = gloss COMBINED weight rating. Combined includes everything the engine is moving, truck, fuel, occupants, splattered bugs, you get the idea...

 

oh snap, I missed the gcwr, was going off of the maximum loaded trailer weight in my head. But thats not bad, back down to 10k.

To get an aftermarked E4OD thats built for heavy service, you will spend a lot more than a grand. You can seldom get a low budget reman for that little. The shift kit is the better option in by opinion, especially if you are going to turbocharge the truck. But it depends on how much trouble you want to go through.

If I understand the trans command system correctly, it allows the operator to modify the line pressure in the run. This would also help, since the E4OD was built for smooth shifting, not good for towing. What does the trans commant cost anyway? shift kits start at $40, but you have to romeve the valve body.

A big cooler is always a good idea, but you should also consider a trans temp gauge.

 

I mean a grand more than a regular stocker. The transcommand can be had for $150-200. I definately would get a trans and engine temp gauge.

 

you don't want a shift kit AND a Transcommand. Get either/or. Banks says too much pressure on the tranny

 

That's a good point, I'm going to look further into each one. Anyone recommend any shift kits?

I was also thinking of new axles to go with a 4.10. I see some with Dana 60s and others Dana 80s. Ideally from what I've seen and read I think I'll probably be getting a 7ton dump trailer. I wont be maxing it out all the time but usually around 3-4 tons. Where can I go to ask about the Dana f/r ends?

 

The 10.25" Sterling rear axle in your truck is just fine.

I have had over 9700 pounds in my dump bed, no axle problems at all.
And yes that bed is on my truck, not a trailer.

Dana 60 front axles, like what they put under the F350 is the one everyone wants.
The TTB front axle is a bit weak.
Your truck with an extended cab should have a Dana 50 TTB, which is the better of the two.

P.S. Ford calls it a TTB (Twin Traction Beam) and Dana calls it IFS (Independant Front Suspension)

 

I've been over 10K LBs with my 250. It would have taken more, but the front end was a little light!

The Air Bags work great, and I'd recomend them to anyone who regularly hauls heavy.
