new to WJs. 6" lift.. no uca?

Hi guys, names devin, new to the forum and to WJs. I just picked up a 2001 WJ with a 6" rock krawler LA lift for $1500! Cant really beat that huh? All it needs to drive is a new cv axle.. so I thought... I was under looking around and noticed that I have no passenger side UCA.. had anybody ever seen this? Normal? Im totally new to wjs and lifts (I also have a 03 kj so im not totally new to jeeps) thanks for the help in advance

i believe at one point, rock krawler made a true 3-link for the WJ. I may be wrong. but its probably just like the IRO set up. Its a radius arm on thew driver side and a single lower control arm on the pass side.....so yes, its fine

I have a RK lift. It is a true 3 link. No radius arm. Passenger side only has a LCA.

Consider yourself lucky. The 3 link (assuming RK designed it properly) is far superior to the radius design. Too bad no one fabs a 3 link for the wj anymore.... for now.

I have the RK there link up front. It flexes like crazy, great setup. The joints are loud though, I am running Johnny joints now.

As already said yes Rock Krawler does not use the upper on the passenger side, i believe that's the same lift a member on here has (85Irocz-28) . He has some awesome flex pics in his build thread over in general discussion if you want to see what to expect.

edit...He beat me to it

I'm really interested in the upper link where it mounts to the body. im considering doing a real 3 link rather than a radius setup. ive been reading some stuff about suspension design over on pirate.

EDIT: Mine are different that the one above, two piece instead of one piece. That design above is better IMO. The RK kit when through a few generations on the design.

I took some pics for a friend a few years back. Just look at the arms direction to orient yourself. The lower arm bolts to the bottom of the unibody frame rail, the upper control arm bolts to the inside of the unibody frame rail, inside the frame and above the location of the lower arm, at the same distance from the axle:





Distance it is from the unibody rail:


The RK upper link uses a heim on the body side, here is a closeup:

This one shows the plate on the outside of the unibody...the plates sandwich the body to hold the uca.

EDIT- Forgot to add the last pic, here it is:
