kris, i'm sad to say this, but ttb's are the new hot setup for bling buggies ala k.o.h. rigs :shaking: don't ask me why, but companies are even coming out with high dollar bling axles for them and a few are trying to develop stronger bolt in centers from what i've read. it's like the damn twilight zone reading about it 
Ive seen that. The "cheap" sets start at just under 2k...without u-joints which are a little over $200 each.
Ive never debated the fact that they do handle bumps/hills/jumps well. What Ive said is they do not handle mud rocks and heavy trail use much beyond stock size tires and mild offroad conditions. Theres too much going on in the axle at any one time to hold up to much abuse.

I am actually impressed with it.......so much so that I am keeping it.......moding it to 8 lug and doing long arms and a small lift....swapping the rear to D60.

Twin I-beam TTB
while i don't have as much ttb hate as most, i still think they are junk. bad design and besides being more complicated, they tear up frames from the stupid amount of leverage they have when they are really being worked hard.

HUGE difference between TTB, and TIB.
I for one know a STOCK hight TIB pickup with 4 inch TTB springs on it will jump like there is no tommorrow. I wish I had some pictures, but my 74 F100 2 wheeler had more air time than a twin seat Cessna.

3 ujoints for one..... The joint at the diff and the slip joint there is a major weak spot. Usually the first to give out. The TTBs are press formed steel welded together, vs cast steel. Ive had TTB axle that was all cracked up and needed some extensive welding to keep it in service.

i had a TTB D-50 break in half on a truck that was never off road, street driven only.
and saw 5 or 6 others that broke in the same place, right at the driver side spring.
the dana TTB axle is a poor design. the axle tubes are thin box steel compared to the thick cast tube of a solid axle.

Pretty much sums up my feelings...
I wonder what ever happened to this guy?
Definition of Twin Traction Beam (TTB) Tee Tee Bee ~
A Twin Traction Beam (TTB) front axle is found in 83-96 Rangers/Explorers 80-96 F150s and 80-98 F250s. Its like a independent and solid axle had a late night drunken stupor sex-o-thon and had a basturd child. The only beneficial worthwile or nice thing I can say about them is they ride good on road while stock and absorb hard bumps offroad in like prerunner trucks. In all other applications they suck. It works very similar to the twin I beam suspensions of 2wd trucks. The axle is hinged on a crossmember that allows each tire to move independently of the other. They are expensive to lift even slightly over stock. The higher the lift the more stress it compounds on to the frame and TTB crossmember and it leads to stress cracks that drastically weakens the frame and is extremely dangerous. Common TTB sizes are D35 (rangers/explorers) D44 (F150s) and D50 (F250s). TTBs are much weaker than their solid axle counterparts. Anyone wanting tires larger than 35" and plan to wheel their truck with any amount of confidence MUST switch over to a solid front axle swap (SAS).
TTBs bring the suck!
