I have Shrockworks full kit. They're ok, I probably wouldn't get them again because of poor customer service from my experience. The nice thing with them is they form a nice flat belly because they all attach to each other.

If you want a gas tank skid, consider lil skips also.

Rear diff is overkill in my opinion unless you are getting really crazy. What do you mean by front lower control arm skids? The ones that actually mount to the arms and move with the suspension? Also probably overkill. The arms are pretty stout. Last I saw all those required drilling through the lower control arm which I didn't like so I sold the set I bought without u stalling them.

One of the most important skids on a 2rd gen is the real control arm mount skids. They protect the rear control arm mounts where they are welded to the frame. They bend easily when playing in rocks. Lotus I believe is the brand most use. Super easy install.
