How much can a TTB take? - Pirate4x4.Com : 4x4 and Off-Road Forum

How much abuse can a twin traction beam in a 1993 F250 handle? What are the practical limits on tire sizes? The truck in question has a 5.8 and a 5 speed.

Although mine's an F-150, the axles are similar except for the whole leaf-coil difference. I managed to break the stock bracket for the driver's side axle beam in two places. After replacing that bracket with a 6" lift bracket, the frame around that bracket's mounting points cracked, which I eventually fixed.

I've got 35" tires on it now, and haven't had any problems as far as shafts or u-joints go, but of course, I don't exactly thrash it off road.

From what i've seen, 35's are a practical limit depending on wheelin habits.

The TTB axle itself is quite strong. The shafts/joints are the same size as other Dana stuff.

Problems with TTB usually stem from cheapo liftkits (unfortunately, thats a majority of them). The Skyjacker Class II stuff is one of only a couple standouts.
The leafsprings aren't going to let it flex much, though.

Your F250 probably has a D50 axle. This axle has somewhat larger joints than a D44, but not as big as D60 parts. Ring dia. is 9", with 30 spline shafts.
Check the bottom of the pig for a big 44 or [b]50]/b] on it.

I would agree with the 35" tire recommendation if its locked. A 50 with open diff or L/S, it could live ok with 37s or so.

ahhjaws · 12-29-2003, 11:14 PM

Yeah, I would say 35's too, not more than 37's though.

FearMe · 12-30-2003, 09:26 AM

If your actually thinking of wheeling it hard don't go over 33's. If you just want the look 44's will work great.

check your hubs to tell what front axle you have, or the GVWR tag. The dana 50 uses the same hubs as a 60, it is obvious which front axle you have.
I've been beating my f-150 for years, with a mildly built 351, grany 4 speed, and 35's nothing has ever broken. A 50 should handle 37's just fine open, locked it may get sketcky,

It has manual hubs on it. Does that tell you anything?

I can get the truck cheap. I was thinking about building a hybrid out of it....take the body off and put a ranger cab and hood back on it....weld up a cage, bolt on 44's (no lift) and give it hell.

Should I pass on this one and wait for a one ton?

TurdBronco · 12-30-2003, 12:00 PM

to use 44's?
Yes.

Paul Gagnon · 12-30-2003, 04:13 PM

If the truck is an F250 it should have a Dana 44, if it is an F250 HD it should have a Dana 44HD if regular cab and Dana 50 if Super Cab.

82F100SWB · 12-30-2003, 05:24 PM

Also, any F250 with the Sno-Fighter package got a D50, even the LD's.
But, the only F250 that's guranteed to have a D50 is an extended cab with a 460 or diesel.
For 85 and 86, EX. cab F250's only came as HD's, later, I'd assume was the same.

Also, the 5 speed behind that 351 is a ZF, if the truck is fairly cheap, I'd grab it, and find a D60 to swap in later, unless you can find a better deal on a F350.

Its on Ebay right now for $665. I think I'm gonna pass on it.

Too many other things going on right now.
