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

Great product

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.

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

Did the job!

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.

The best thing I bought for my truck. Had an exhaust leak. Fixed it right up. Been holding strong for over 2 years. Great product.

Great bolts for header install on gen 4 ls engines

Replaced broken factory bolts on 2005 Silverado.

APR bolts speak for themselves. They are there some of the best bolt on the market

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