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

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

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.

ARP is a great company, with great products!!

ARP is worth the money. Will buy the ARP head bolts for my 2004 GTO when I put the stage 2.5 CNC ported 243’s on. Beats Torque-to-yield by miles.

Best there is. 100% satisfied

I Love theses bolts thank you

Got these for my 2007 Silverado when replacing the engine. Considering how often the factory bolts break, my mechanic thought this was a great idea.

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.

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

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
