After breaking a bolt on my intake manifold cover like a complete newb, I ordered these. 2005 Chevy Silverado 6.0. They're must cheaper than OEM. And they worked just fine with "2 day shipping" which rarely means 2 days anymore with Amazon lol. They came in 3 days.

I didn't end up using them as of now, however the bolt quality seems good so I may use in the future.

I bought these based off the reviews I read on here but these bolts ended up being about 1/2†too short for use with the replacement dorman intake manifold. I have a 2002 Lm7 5.3 truck engine. I kept these anyways for other intakes I may use in the future. These are no doubt good quality hard to find bolts so Ill save them for other projects. FYI, 6M X 1.0 90mm long bolts worked perfectly for my applications.

This will not work with a LS motor. The bolts are almost half too long. 🤦ðŸ½â€â™‚ï¸. The description is a lie and now I wasted money on this crap and I can’t even use them.
