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

nice.

Do it right the first time with these Bolts! Best around in fit, finish, quality! Spend the money on the right part for your application!

used these to replace the broken bolts on my LS2

Bolts threaded in nicely. 10/10

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

Great bolts for header install on gen 4 ls engines

Best there is. 100% satisfied

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.

seem to be quality.
