Product Details

The ARP 400-1208 Header Bolt Kit provides professional-grade fasteners engineered specifically for exhaust header installation. This comprehensive 16-piece kit features 12-point head bolts manufactured from premium black oxide chrome moly steel, delivering exceptional strength and durability for demanding engine applications.

Key Features:

  • 16-piece complete bolt kit with premium washers included
  • 12-point head design allows easy socket access in tight spaces near exhaust pipes
  • Black oxide chrome moly construction rated at 170,000 psi tensile strength
  • Substantially stronger than standard Grade 8 hardware
  • Precision-manufactured threads to prevent cross-threading during installation
  • Heat and corrosion resistant for long-lasting performance

ARP's advanced metallurgy and manufacturing processes ensure these header bolts deliver superior clamping force and reliability compared to OEM fasteners. The 12-point head configuration provides multiple engagement points for added security while allowing the socket to fit closer to exhaust components in confined engine bays. Perfect for street performance, racing, and heavy-duty applications where header fastener failure is not an option.

Great price and good company to buy from!

I ordered CV axles from Autoplicity and had them in less than a week! Definitely the best prices for quality product on this item. Will be a return customer for sure!

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Easy to find the part I was looking for. Looks like the shipping will be quick. Thanks!

Sweetest price on this K&N Filter anywhere! Shipped within 24hrs too. I'm coming back to shop for my car next.
