CUSTOM LINK SUSPENSION SCIENCE
Q I’m working on building a custom three-link front suspension for my very custom ’48 Willys CJ-2A. The tub is stretched and it’s on a custom frame. I mainly use it for trail riding and rockcrawling, but I do drive it to and from the trails so road manners are important. The tires are 39s but I may go bigger. My axles are Dana 60s and I will be using 12-inch-travel shocks. Are there any hard and fast rules to follow when considering link suspension geometry? I’ve done a ton of reading on the subject, but it’s honestly all a little overwhelming.

There is a ton of good information on the Internet about link suspensions, but it is hard to wade through. Experience counts, and books have been written on this subject. Still, some of the info out there isn’t that great and some is good but hard to understand. Much of the online geometry talk is aimed at road cars that have independent suspensions with very little travel (compared to off-road rigs) and need to
