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

Great bolts for header install on gen 4 ls engines

Que puedo decir son arp

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

Worked great on my 2015 silverado 5.3

Bolts threaded in nicely. 10/10

The best thing I bought for my truck. Had an exhaust leak. Fixed it right up. Been holding strong for over 2 years. Great product.

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.

Bolts came open and missing 2 washers ..

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

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