I agree Dustin. Think there is more to it than meets the eye. However, in design, I think they are a true 'traction' bar, as the axle tries to wrap the caltrac can actually put additional downward force on the axle aiding in traction. Regular bars just prevent axle wrap, nothing more.
The Cal-Tracs made my lowly 450hp 2wd truck at least a little bit useful on the street. Without them it would just spin until you lifted, with them it would just chirp tires on the shifts, but then they'd plant and go. Money well spent.
I agree 100% I do think that a traditional traction bar still provides some downward movement just not in the same manner. I put on a set of traditional ones this last week and could actually tell a difference...again not the same tho
