CRC vs Triangulated 4 Link...

Just thinking about this the other day and was wondering what others thoughts might be on this. Purely from an academic standpoint I am comparing:

Full traction CRC rear suspension set up which replaces the single track bar with 2 opposing track bars mounted on a swivel above the center of the axle

Custom Triangulated 4 Link like what we typically see on the custom builds on this site

I'm guessing you can't get as much vertical travel with the CRC swivel thing?

It would be interesting if Jeep did something along these lines for the new JL wrangler. Thats what got me thinking about it I was wondering if they would advance the suspension set up in some way.

I believe pinion angle and travel are the issues with the CRC link. Great where tons of travel are not needed.

If you have enough triangulation in your custom 4 link, you don't need a track bar or this watts link. Also, with this watts setup your roll center height is where the pivot on the diff is. Which looks from the pictures to be even with or slightly lower than stock.

The watts link has been around almost as long as the track bar. They do exactly the same thing. One keeps the RC height static, one lets it move up and down with the vehicle. I don't think there is an advantage to having it static on a Jeep. I do think there are disadvantages to having a more complicated system with more parts on a Jeep.
