Is this the leveling kit company that everyone on here recommends. I heard they only sell on eBay but found this site and wanted to make sure it's the same company everyone suggested.

Yep, that's them. Not sure about these leveling kits anymore, but back when I got mine, they were the only spacer that were offset so the upper control arm did not make contact with the coil. They also make double-pin rear blocks in custom sizes. Good guys to work with.
