Product Details

The ARP 420-1411 is a premium 14-piece header stud kit designed for secure, long-lasting exhaust header installation. This kit features hex head studs manufactured from Stainless 300 material, which provides exceptional resistance to corrosion and extreme heat while maintaining a nominal tensile strength of 170,000 psi—substantially stronger than Grade 8 hardware.

Key Features:

  • Stainless 300 material resists corrosion and extreme heat
  • 170,000 psi tensile strength for superior clamping force
  • Includes 14 studs with premium-quality washers and 12-point nuts
  • Compact 12-point nuts allow easy socket access near exhaust pipes
  • Unique nut-starter nose design helps prevent cross-threading during installation
  • Available in NASCAR drilled configuration for safety wire applications

Each ARP header stud kit includes precisely the number of components needed for your application, ensuring proper installation with professional-grade hardware. The stainless steel construction makes this kit ideal for high-performance and racing applications where durability and reliability are critical.

I purchased a complete set of EBC usr sport rotors for my car. No other companies can come close to their pricing. AAAA+++++

great prices only down side is not alot of detail on products shown.

They had the lowest price and great communication. Will order from them again thanks

Great seller, lowest price on web, super fast shipping order 25599, will buy from again without hesitation.

Found part in stock and not at competitors.

This site was just like shopping at a real store. It was easy to make my order and I was able to do it on the go on my smartphone which is important to me that a site is compatible with handheld. Bravo

Great prices for the parts I needed to replace on my SUV, a bit hard to reach customer service when I had a question about the order. When I finally did reach CS, question was answered without any issues, shipping costs seem a bit high.

The ordering process was simple and user friendly. The pricing was the lowest I could find for a brand new AMP Powerstep for my Ford F150. The tracking number was provided and the item is scheduled for FedEx ground delivery in 3-days.
