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

After the challenging task of removing the broken oem bolts, I replaced them with these. Perfect fit and they look nice. The exhaust is nice and quiet now. Dont forget to get new gaskets.

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.

Best there is. 100% satisfied

Exactly what I was looking for

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

Great bolts for header install on gen 4 ls engines

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

excellent quality. works perfectly for my 351W rebuild.
