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

Perfect for my 5.7 LS1

After the challenging task of removing the broken oem bolts, I replaced them with these. Perfect fit and they look nice. The exhaust is nice and quiet now. Dont forget to get new gaskets.

These are great header bolts. And are really heavy.

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.

ARP is a great company, with great products!!

used these to replace the broken bolts on my LS2

Chevy 2500 6.0 worked as they should haven’t had any issues so far

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.

Worked great.

excellent quality. works perfectly for my 351W rebuild.
