Lang/Kastar makes the rethreading kit
Irwin makes the bolt-out kits I believe.
I second the Irwin rebranding. I had the starter bolt out kit my mom got me for Christmas, probably a decade ago. I've used them here and there, but for trivial things that I could have completed with a vice-grip.
However, I had to drop my transmission this spring and if I wouldn't have had this kit, I would not have gotten the nuts off of my torque converter.
I wanted to get the completer kit to fill the case after that *** saving, and had to get an Irwin set to finish the set, because Craftsman had changed their set grouping.
Definitely recommend getting this kit.
