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!

BFG all terrain T/As are not, have not, and will not be an offroad tire. They are not good in mud, rocks or other forms of off road terrain. Please take note of this before mentioning the BFG A/T and asking if they are a good offroad tire. If you want/need a good offroad tire get these.
Interco Tire Corp. Super Swamper Boggers.
This is an offroad tire.
