Gate post

Trinity

Ive installed some vinyl fencing with a gate in the center of a 10' section. Gate is also vinyl approx. 3' . I mounted 4x4 post to concrete for the gate post, but they are a little unsteady. I need to strengthen these up with kickers, L brackets, etc... any good ideas?

Define, "unsteady".
It sounds like you skimped on the amount of concrete around the post and/or didn't dig it deep enough.
Pull it out and do it correctly. There is no after thought compensation that will work.

Well I guess I was a little blunt on how I said mounted 4x4's. I mounted them directly to the concrete with brackets, this is probally temp. so I did'nt want to cut, dig, $ pour the existing concrete. Just Anchor Holes only.

You already know this is not the way to do it. You cannot hang a dynamic load like that.
You dig the hole down at least 36" or below the frostline. You dig the hole at least 3x wider then the post. You fill the bottom of the hole with gravel so it drains away from the post bottom. Depending on the weight of the gate, you can concrete the post in or you can fill the space around the post with an angular gravel, tamping every 6" or so. This keeps the water away from the post and will keep the post anchored. If you're uncertain about the weight, dig the hole 4x the post and fill with gravel. I've hung 3'x5' cedar gates from this without an issue.
