Dear Welder Series… 1969 F100 Four Link Install Question

Dear Welder Series…
I recently purchased a triangulated 4 link universal kit. I’m putting it in my 69 F100 swb. I have a couple ?s. If the horizontal angles on the upper and lower bars are the same will it have adverse effects if the sitting ride height angles are at 10 deg higher on the front? I’m thinking of raising the front frame mounts up to 10 deg so they won’t be so close to the ground. Also, is there an optimum angle for the triangle? As in looking down on it. I’m pretty close to the angle on the upper frame brackets but was wondering if any +/- is OK?

Dear Kevin…
Kevin, a 10 degree angle on the bars would put the front about 4-1/4″ higher than the rear. This would cause the rear end to “walk” as the truck leans in a corner. This “walking” will make the truck steer from the back end and could be dangerous. I’m o.k. with the front of the bar about 1″ higher than the rear. The angle of the upper bars relative to frame center line can be changed slightly. I don’t have a maximum spec to give you because we haven’t tried to see when it becomes unsafe. Thanks for these questions.
