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

Bolts came open and missing 2 washers ..

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

nice.

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.

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

Can’t beat arp

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.

I Love theses bolts thank you

Works good for headers I put on my 2015 camaro ss.

Did the job!
