4-link question

[NPloysa]

How far apart between the upper and lower arms? My mock up is 8 inches on center. I can get a pic up tomorrow night... Should I make them further apart? Should the bars be parallel with respect to eachother AND the ground, if I had to pick one which should I choose? There is a good 4-link site here: http://www.afcoracing.com/tech_pages/4link.shtml that I am trying to go off of for some info.

I know there are several ways and many manufacturers do it different. Kelderman has different length arms and different angles. Our stock Dodges have two arms on the front axle, they are angled upwards to the frame, inwards toward the center of the truck, and not in plane, one is further in than the other. I'm just asking for opinions on the best way.



I will not offroad, there is minimal lift involved, and very little flexing, so I guess I should do it the easiest way possible.

From reading all my posts about this you also know it is taking forever! No need to rush something like this though!

I appreciate the enthusiasm but this is one of those cases where learning by doing could have very serious repurcussions. There are multiple trade-offs to be made when deciding on the link geometry and then you have the actual structural design issues to deal with.



Have you read "Chassis Engineering" by Herb Adams? It's a good coffee table reference book.
