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

used these to replace the broken bolts on my LS2

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.

Worked great.

Well made product just like other ARP products.

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.

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.

ARP is a great company, with great products!!

Replaced broken factory bolts on 2005 Silverado.

Perfect

Best there is. 100% satisfied
