54,000 dollar suspension question.

[hotrodrookie]

I built a parallel link setup for my truck but originally wanted to go with the triangular.

My truck being a second series has a narrower frame then yours, this steered me away from the triangulated system because I couldn’t make my upper bars long enough and give them enough angle to function the way I wanted.

For my design I basically went off of maximizing instant center adjustability with the bars. (more for drag racing) All this consists of is the angle at which the upper and lower bars are positioned and the location of their resulting imaginary intersection point. A triangulated system creates this same instantaneous center crossing of the upper and lower bars, as well as centering the axle between the frame. Being that you want to drop it with bags, just make sure the bars don’t bind through the vertical cycle of the suspension and I don't see why it shouldn’t be a problem.
All that said, my truck isn’t done so I don't know how it rides and I haven’t designed, built, or driven a car with a custom triangulated or parallel 4 link, so ya, my 2 pennies.
