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

The bomb!!

Can’t beat arp

Great product

Worked great on my 2015 silverado 5.3

ARP is a great company, with great products!!

Starting to rust only 24 hours after installation. I used these when installing headers on my 2001 Corvette, I havent quite finished the install of the rest of the system so the car has not even been started, yet these bolts are already rusting. Other than that, they work as a bolt should. But not worth the (almost) $40 in my opinion.
