Review: Saved my rear differential - excellent. I fixed my 2012 Jeep Patriot and stripped the housing in the rear differential. it worked perfectly and I was able to torque it to spec. only improvement to the kit would be a suitable drill at the size. be careful with drilling. move on slowly
Review: Great product - Did the stripped plug on my 04 Sportster and worked great. Just have to make sure you get the tang out of the cylinder if you break it off and it falls inside. I had a bore light and I could see that it had come out after I blew it out with compressed air. Had it at top dead center and made it easier to deal with. If you use some long needle nose that are slim you can just reach in and break off the tang.

### ⭐⭐⭐⭐⭐ Took 2 tries but now I am a pro at it
*by S***E on November 15, 2023*

I had to replace the Heli-Coils in my Wilwood calipers/brackets. These worked great. it took me 2 times until I got it right. But then it was easy as pie. I just wasn't pushing down hard enough when turning in the heli-Coil at the beginning. After that piece of cake.
