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

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.

Exactly what I was looking for

I installed these bolts on a 6.0 LS with long tube headers and they fit spot on! I RECOMMEND!!

It fit my 05 Silverado 1500, great replacement for the oem broken exhaust manifold bolts

Best there is. 100% satisfied

Replaced broken factory bolts on 2005 Silverado.

Installed headers. Been riding on them for about a month now.

Used these to replace the broken header bolts on my 03 2500HD 6.0. Typical ARP quality, very nice finish and I have peace of mind that these bolts wont fail as easily as the OEM bolts did.

Perfect for my 5.7 LS1

excellent quality. works perfectly for my 351W rebuild.
