    How do I go about switching to a 4 link suspension system? What would be the benefits of switching to 4 link?

    I'm pretty sure it has a 5 link stock. Why would you want to change?

    Pretty much jeeps already come with a 4 link these days. Upper lower control arms. 1of each on each side of both axles. You could improve the jeeps system by switching to coil overs, and further improve by installing a triangulated system. The whole idea is to get more flex (articulation) of the axle while still keeping the cab stable. There are many coil over kits out there that do a great job.

    The Trac bar is the 5th link......kinda sounds like a movie.

    This is an example of a 5 link system:

    compared to a 4 link:

    a 5 link generally give more lateral strength at the expense of extra weight.

    Will the 4 link in the front prevent death wobble? Is that enough side strength, or are you still having to run a track bar in addition to the 4 link in order to prevent death wobble.

    I will have to ask my friend that owns Moab 4x4.

    Yeah, I'm not sure about that. I would imagine the 4 link would be just as prone. From what I have found, Jeep only used a 3 link system in the front. A 4 link is mostly for rear suspension set ups.

    In all the link systems I see online for the front end of a Jeep they do not count the track bar as a link.

    I honestly would not want to change what I have, a friend of mine is trying to sell me his 6" skyjacker lift so he can "switch to a 4 link", those were his words so I was just kinda confused about it. I'm not brand new to the jeep world just haven't actually built my own yet I have previously bought something already built but I've definitely learned my lesson.

    I agree with Bryant for the most part. I think the JKs were pretty well designed.

    Mine is actually the longer version TJ but still it's cool overs all around and from the diagrams everybody shared it would seem that it's technically already got a 4-5 link suspension

    Yep. I have watched people do custom 4 links and they don't change much from OEM. I've often thought while researching that it wouldn't be worth the effort unless you made a double triangulation 4 link. As soon as I learn to weld without splattering everywhere I'm going to try something like this.
