Used these on a 1998 Ford F150 4.6L to repair rusted off studs on left exhaust manifold. Great product at a fair price. A breeze to install. Hardest part was cutting off the old studs but a 3″ cut off wheel made short work of them. These should work great on any manifold that has a “stud ear” on it.

Works great. Saved me at least a $1000 shop bill. I would recommend this to anyone with an older F150.

Great Solution! Compared to the dealer wanting to replace the exhaust manifold.. and being worried the studs on that may be a problem.. or trying to retap the manifold. this is the ONLY solution. WAY better than C-Clamp solution!

Worked great. Installed it in ten minutes. Garage had quoted $500 to fix it. Said the manifold had to be replaced. Fixed it myself for about $20.

The exhaust studs broke on my Expedition and I knew I had an expensive fix ahead of me. I was looking for new studs and came across this product on Amazon. I decided to give it a try. The product arrived exactly on time. The product is straightforward and instructions were simple. I am not the most mechanical guy but was able to install these in about 30 minutes. Most of the time was spent grinding down the broken original rusty studs a bit which I did with a dremel tool. The product worked perfect and after a month it is still perfect. Would DEFINITELY buy again.

Great product nice to see made in USA. Great guys to deal with Thanks.

Excellent seller, excellent product, works great! Great communication AWESOME!

This product was easy to install and did exactly what it is supposed to do. I did have to grind off the original (rusty) manifold studs with my dremel tool but then the installation was a breeze. This saved me a ton of money. Great Product !!
