Product Details

The ARP 100-1111 is a premium 12-piece header bolt kit featuring hex head bolts designed for secure exhaust header installation. These high-performance fasteners are engineered to withstand the extreme heat and vibration inherent in exhaust applications.

Key Features:

  • Stainless 300 material construction for superior corrosion and heat resistance
  • 170,000 psi tensile strength rating, significantly stronger than Grade 8 hardware
  • Hex head design for reliable installation with standard sockets
  • 12-piece complete kit includes premium-quality washers
  • Black oxide or stainless steel finish options available
  • Ideal for high-temperature exhaust system applications

ARP manufactures these header bolts to exacting standards, ensuring reliable performance in demanding motorsports and street applications. The Stainless 300 material maintains its integrity even under extreme exhaust manifold temperatures, while the superior tensile strength prevents stretching and failure under thermal cycling. Each kit contains the precise number of fasteners needed for your header installation, along with matched washers for proper load distribution.

Great value and fast delivery. The tire arrived slightly crushed from weight which possibly occurred during shipping. The out-of-round quickly went away after approximately 20 miles of driving. I'm very impressed with the great price and delivery time. Thanks again.

Great priced and quick delivery. AWESOME!!!!

It was easy but wanted to talk to some one don't see a customer service number that would be helpful

Super easy , great price !

Fast shipping, great product.

Bought a Husky gearbox for my Silverado, great price and a great product. Install was simple and the fit was perfect. Gone are the days of opening the rear door and all the items under the seat sliding out. Great for my hitch, tow straps, jumper cables and other miscellaneous must haves in a truck. Great seller the price was the best on the net even with shipping. Item arrived quick and in perfect shape. Thanks!!

Great prices, filled and shipped immediately. Best deal around!

They have the best unbelievable prices and availability on all kinds of automotive products on the market and like I said the prices are great i will buy from here in the future

I pieced a roof rack setup from all over the internet, and Autoplicity consistently beat every other vendor on price and shipping, even most auctions on eBay!<br>I found the site confusing when searching for items directly (why was the "Roof Racks & Cargo Carriers" dropdown empty, when Google showed their ads for tons of these products?). Since they always came up at the top of a Google Shopping search for products, using their website's internal navigation wasn't ever necessary.<br>Customer service guy was a little snippy, but I could have just been interrupting his lunch.

great price but the shipping a bit high
