Product Details

The ARP 100-1207 header bolt kit provides a premium fastening solution for exhaust header installation. This complete kit includes 12 pieces of high-strength bolts featuring 12-point heads for easy access in tight spaces around exhaust pipes.

Key Features:

  • 12-point head design allows socket placement close to exhaust pipes
  • Constructed from Stainless 300 material for superior corrosion and heat resistance
  • 170,000 psi tensile strength—significantly stronger than Grade 8 hardware
  • Complete kit with 12 bolts plus premium-quality washers and nuts
  • Ideal for high-temperature exhaust applications
  • Black oxide or stainless finish options available in ARP lineup

ARP manufactures these header bolts to withstand extreme heat and corrosive environments that exhaust systems endure. The stainless material maintains its strength and integrity even under the most demanding conditions. Each component is precision-manufactured to ensure proper fit and reliable clamping force for secure header installation.

Note: ARP also offers NASCAR-spec drilled models for safety wire installation, providing additional security for racing applications where vibration and loosening are concerns.

The best price I could find and it arrived in 2 days! I'll be doing business again.

thank you

They have the best prices and fast shipping too.

Excellent low price, super fast shipping, and great communication. Top notch seller. Recommend highly!!

Ordered the Auto Ventshade Ventvisor Deflector 4 pc. (Model 94856) for my 2000 Toyota Camry XLE. Was easy to install with no tools, just use the included strong double sided adhesive tape. Instructions that came with it could've been more detailed on where exactly to install the ventshade as I had to remove them tediously, realizing I had to put them a little higher. Also, there seems to be an unsightly gap between the front and back windows. Works as designed. Satisfied with product. Fast shipping by Autoplicity.

Best price found quick shipping couldn't be easier will buy again.

Unbeliveable customer service and super fast shipping. I had a question about my order and I was able to use the online chat function to instantly connect with a customer service agent that was quick to answer all my questions regarding my order. I am very pleased with the level of service I received not to mention the great price they offered on the item I purchased. I will be sure to continue doing business with Autoplicity for my automotive needs. Thanks so much. A+
