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.

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

Replaced broken factory bolts on 2005 Silverado.

Perfect for my 5.7 LS1

Description misleading, my headers require 3/8 -16 thread, description describes 3/8 flange not thread size

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

These are great header bolts. And are really heavy.

Remember not to over torque and strip your heads threads.

Worked great on my 2015 silverado 5.3

Great price and product thanks
