Product Details

The ARP 100-1211 header bolt kit provides premium-quality fasteners specifically engineered for exhaust header installation. This complete kit includes 12 pieces of high-performance bolts featuring 12-point heads for superior wrench engagement and easy access in tight spaces near exhaust pipes.

Key Features:

  • 12-point head design allows for easier socket placement close to exhaust pipes
  • Chrome moly construction with black oxide finish for corrosion resistance
  • Rated at 170,000 psi tensile strength—substantially stronger than Grade 8 hardware
  • Complete kit includes premium-quality washers and hardware for installation
  • Manufactured to ARP's exacting standards for reliability and performance

ARP's header bolts are designed to withstand the extreme heat and vibration encountered in exhaust applications. The black oxide chrome moly material provides excellent durability while maintaining proper clamping force under demanding conditions. Each bolt is precision-manufactured to ensure consistent torque values and secure header mounting for both street and racing applications.

Fast sipper would recommend and buy from again

.

Tracking links do not work. When i click on them it just takes me to my phone ,as a phone #. That is the only thing i don't like.

Thanks Autoplicity you had the best prices I could find, fast shipping, and everything I ordered was exactly what I was looking for! Great Customer Service!

The Amazon checkout made the process very seamless. Thanks!

The price was right, and they were very helpful and told me all about the product I ordered, and had it shipped out to me quickly! <br><br>Thanks!

This was my second order with Autoplicity. The first order I had to call to get an update, but just happens the part was out for delivery the day I had called. This second order went without a hitch! In both cases, shipping was fast and the products delivered at great prices, not to mention some of the best prices on shipping. I will definitely look here for my future parts needs!!

It took a day or two for them to ship my order, but it arrived quickly once shipped. The price was by far the best available.
