Dorman 03133 Exhaust Stud Kit - M10-1.5 x 62mm Compatible with Select Models

I bought these to replace the worn and stripped factory studs and nuts, on my GM LS V8 engine’s OEM exhaust manifolds/headers. They were a tad longer, which wasn’t a huge issue at all, since I needed to use a deep metric hex socket anyways.These are stainless steel, so they don’t rust fairly easily at all, which is a great plus. I made sure to re-tighten them after they heat-cycled for the first time and broke in. They’ve stayed tight ever since, and I have no complains and would gladly buy them again in the future!

Thank you

Used it on 2017 Tahoe. Dealership was selling these nuts for a ridiculous high price.

Product worked die intended use.

Great

Ordered new cats and ordered these because I wanted high quality studs for the new cats. Touched them with some copper antisieze. Very tough compared to what came with the cats.

good product

On the OEM part, there is a hex head at the end of the bolts. This allows you to both remove and install the bolts into the flange. These bolts lack that feature, and if you’ve ever worked on an old exhaust, it’s likely all rusty and corroded. So, without a way to tighten these into the flange (except with your fingers) and—looking ahead—without a way to remove them if I ever had another exhaust leak...I chose to use the nuts but not the bolts. And I could’ve bought the nuts at the hardware store for a fraction of the price.
