ROCK KRAWLER 4-Link SA kit (Pics!)

Alright! So during a camping trip to Hollister last month I managed to snap off my rear track bar/upper control arm mount on the rear axle
(since this was early in the day it called for more beer and being a passenger for once!)


I got the Jeep towed home with the help of my buddy's AAA insurance!
Then I had to work on fixing it

I decided to go with the ROCK KRAWLER Short Arm 4-Link setup. So far it has much more travel flexin.. but I still have to chop my exhuast to ensure no rubbing on the trails.
The Pics:

This Truss is huge!


Adjustable lower Control Arms are needed for pinion angle. I went with the RE Super Flex.
The RK kit also comes with weld-on strenghtening plates for the frame side of the upper CAs.

And some flex shots!


Anyways.. that's it. It rides awesome and I can't wait to get it on some trails! Cheers everybody!

Nice man, I've really enjoyed mine. I'd recommend running the axle end joints on the two closest holes. More triangulation = stronger.

stronger? the angle the arms are run at i dont think it would matter at all, but if you know something i dont explain, i love learning. I am thinking that if you got to move them more than an inch or inch and a half a side then maybe, but they are already triangulated alot since they are so short.

The RK instructions tell you to use the inside holes on a TJ.

The outer holes are for a ZJ.

Is that a Sierra Nevada Pale Ale?

Looking good...A group of guys from the South West Regional Forum are running Hell Hole Resivior this weekend near Placerville if you want to test that thing out. And some Pale Ale sounds great about now as I sit at work and Web Wheel.

I think for now I'm going to keep them mounted where they are. Maybe I'll change it after I wheel it some.

Placerville is a little too far for me this weekend, and I won't get to chop my exhaust till Sunday (Gotta use my buddy's welder for the 'free-effect'). But I am definatly going to test drive it to this little spot in Martinez on Sunday after the chopping.

Sierra Nevada all the waaay!!!! Always required on camping trips

So I finally got the work done on my exhaust. Out of the way, and no more rubbing! Its got a much deeper sound to it now also.
I'm finally going to get some real wheelin in this weekend too
I will be running Deer Valley Trail (South to North) on saturday morning, then taking my first trip on the Rubicon! Pretty excited.... If anybody else is going to be out there, be sure to look for my TJ!

Some pics of the exhaust:

I am looking for more feedback on this setup. The only other thread I can find on them is Imped's. But I would like to hear more feedback about the set up.
  • Specifically thoughts/opinions on running these vs. Currie uppers?
  • I have seen a few people get a small stretch (1") out of Currie and Rokmen arms. I assume the RK does not allow for this?
  • How is maintenance with the those joints?


Thanks guys.

With standard uppers, you still have to run a track bar. The whole point of triangulated uppers is to ditch the track bar and the associated bind and lateral movement of the axle throughout the suspension cycle. I run Currie lowers and the RK upper setup. With the gas tank back there, you cannot "stretch".....with that said, my wheelbase is slightly longer than stock but I still wouldn't consider it stretched. With 4" of up travel, I've adjusted the arms to give me 1/8" between the Rokmen gas tank skid and diff cover at full bump....it takes trial and error with lower/upper length to get things that maxed out. Unless you're going to run a fuel cell, that will be of no concern with the RK setup. There's PLENTY of adjustment room on the arms. Where the axle is located now and given my pinion angle, the arms are almost as short as they can go. I could safely get another 3" out of them. The maintenance on the joints is virtually nilch. Keep them free of grease. Just wipe them down and lube with some 3 way oil every once in a while. They have remained silent. The rubber bushing on the other side is maintenance free and also silent.

Regarding the truss hitting the tub--I've got a pretty low rig and at full bump, there is still at least 2" between the truss and tub. Your gas tank and diff cover will be hitting completely before the tub and truss ever meet.

I've been running it for 3 years now and can't say I've had any real issues with it. I did have one bad joint that RK switched out but nothing since. Maintenance wise I could have been better also but as I said, no issues.

Knowing what I know now, I'd spend the Money and get the Currie. Although I haven't had any issues with the RK joints, I think the Currie setup uses an easier to replace joint (Johny) should it be needed.
