I installed the lift yesterday and am installing the antirock now. The arms have a lot of side to side play, even when fully tightened. Bar is even on both sides. Are they supposed to have play? On the same topic, instructions say sway bar links should be set to 10.5 inches center to center for this lift but that is WAY too long and I darn near have to shorten the to the shortest setting. Any advice on either of these items? Thanks!

I don't know what you're meaning with the side to side play, but for the length of the links you want it parallel with the ground at the middle of your travel. So for a shock that's 50/50 up/down it would be parallel at ride height. For a generic 4" lift your angle looks roughly correct.

Side to side meaning the arms where they mount to the bar that goes through the frame. Seems that once any tension is put on the front, things naturally snug up. With tension, I cam get side to side movement from this.

Are the arms moving at the splined connections? If so, tighten the bolts at the clamping ends.

Bar is definitely tight in the bushings. I don't think we can tighten it any more.

The tightness of the torsion bar at the bushings in the frame crossmember is not something that you control. What about the splined connections?
 
Where the black arms slide onto the splines is where I have the side to side play. Almost like it needs a spacer in there. I am going to reach out to Rock Jock today and see what they say.

After speaking with RockJock, the do offer a shim pack to address this.
The arms are also not parallel so I will need to compare them side to side and see if one of them is cast incorrectly or it is the bar. Sounds like they will be sending me some sort of replacement once I figure out which piece has the issue.
 
Yes mine did have some play even when tightened down. If you grab the other end it did wiggle a little bit but I never had any problems with it. I have since switched to the Sway-Loc just because I like the on road feeling better and not for any other reason
