Hey guys, I recently purchased a 2012 Wrangler and am in the process of identifying everything that’s been done to it. I was looking for a 2012+ Wrangler to build myself and ran across this one for what I think was a good price considering I could buy the parts alone for the price of it. Anyway, I’m wondering if anyone can help me identify the rear track bar/axle truss that’s on it. I’ve scoured the internet but am coming up short It appears to be a track bar and truss combination.. The bars come down from both sides of the frame and connect to an arm that pivots on the truss. The drivers side connects to the front, and the passenger side connects to the back. As the axle moves up and down, the bars work together by pivoting on the truss to keep the axle centered. The system seems to work great but has a lot of moving parts. The benefit is that the axle will move straight up and down regardless of lift and articulation but instead of having two joint like a typical track bar, this system has 5. Any help identifying this part would be appreciated. Here’s a photo for reference. Thanks for checking it out.

 

Looks like the Full-Traction CRC-Link, but the bolt pattern and diff skid doesn't match. Maybe updated/outdated model?

That seems like a lot of money to replace the rear TB with something designed around a bolt-on truss. It also doesn't seem like anything that improves articulation since you're still connected by the same four control arms. Maybe I'm just not "getting it" like I should be.

 

TRAUMAhead, I think your right on the money! I’ve been searching for weeks to figure this out. I even went to the local 4wd shop to see if he could identify it but he said he had never seen one before. I see what you mean about the bolt pattern and agree with you. It could be an outdated version since the lift appears to have been installed around 2015. The bearing in the center looks replaceable so that’s fantastic.
resharp001, I agree, it is an expensive way to do things but I think it should improve drive ability rather than articulation by keeping the axle centered regardless of how it travels up and down or articulates.
I’d be curious to compare ride quality to another JK with around 6” of lift. I do seem to remember looking for ways to lower my track bar bracket on my 98 ZJ with a 5.5” lift because the sideways movement was noticeable over large bumps but that was 20 years ago and unlike my memory, suspension components have improved. Thanks for the help.

 

I didn't realize the jeep had that much lift, and now that makes more sense. In the normal scenario you're wanting that rear TB as high and flat as possible so we all use a raised bracket on the axle side. When you're netting 5+ inches of lift the typical raised bracket just ain't enough. Also explains the bolt-on truss......which really isn't about axle strength as it is a method of getting that center mount raised so high.
