ARP Chevy LS 3/8in Flange Hex Header Bolt Kit

APR bolts speak for themselves. They are there some of the best bolt on the market

seem to be quality.

Top quality, nice washers to distribute the force, secured kooks headers to my cts-v. longer and overall better looking bolt than the cheap kit used previously. If I have to remove the headers in 10 years my hope is these back out nice and easy, and ARP is the name for that.

These are great header bolts. And are really heavy.

Got these for my 2007 Silverado when replacing the engine. Considering how often the factory bolts break, my mechanic thought this was a great idea.

nice.

Great bolts, by a great company, wouldnt expect anything less.

Replaced broken factory bolts on 2005 Silverado.

Can’t beat arp

Installed on an 09 G8 GT, fit perfect, and of course stellar quality. Perfect for anyone doing headers or replacing factory manifold bolts on LS based blocks. It’s also a lot more convenient and easier to use a 10mm wrench in the spaces since the head is smaller on these. With them being smaller it even stopped the bolt from contacting the spark plug heat shield
