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

Can’t beat arp

Well made product just like other ARP products.

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.

Highest quality fastener you can buy. Make sure you measure your header flange like I didnt. Got lucky and ordered right one this time.

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!

The bomb!!

excellent quality. works perfectly for my 351W rebuild.

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.

Top quality, nice washers to distribute the force, secured kooks headers to my cts-v. longer and overall better looking bolt than the cheap kit used previously. If I have to remove the headers in 10 years my hope is these back out nice and easy, and ARP is the name for that.

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.
