The pull to the side is something not adjusted right with your arms. If stock arms are used and it's pulling, I'm guessing it's because of a track bar misalignment. AEV suspension is designed with the track bar bracket on the axle end so this may be it.
I have the brackets on my rig, with Rockkrawler arms, RK track bar, and Poly track bar mount.
I have no pull. The brackets made it ride smoother, and helped a driveshaft vibration that I just couldn't cure with arm adjustments. I'm not entirely sure what the brackets did that cured the vibe, but it fixed a headache so I'm happy.
