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

Worked great on my 2015 silverado 5.3

Best Bolts. ShortyHeaders install 4.8 v8 07 Silverado 1500 z71 (new body style) torque to 11lb.ft start it, let it get hot, then torque to 18lb.ft. Good to go, have not came loose yet.

seem to be quality.

Replaced broken factory bolts on 2005 Silverado.

Perfect for my 5.7 LS1

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.

Worked great.

had to replace the header gaskets so decided to go with new bolts while theyre off. I have always used ARP in all my cars. No problem whatsoever and like always a perfect fit. 2010 Camaro SS LS3

These are great header bolts. And are really heavy.
