Product Details

The ARP 400-1400 header stud kit provides professional-grade fastening solutions for exhaust header installation. This 14-piece kit features premium Stainless 300 material studs and 12-point nuts designed specifically for high-temperature exhaust applications.

Key Features:

  • Stainless 300 material resists corrosion and extreme heat without degradation
  • 12-point nuts allow easy socket access in tight spaces near exhaust pipes
  • 170,000 psi tensile strength—substantially stronger than Grade 8 hardware
  • Unique nut-starter nose on studs prevents cross-threading during installation
  • Complete kit includes studs, premium washers, and 12-point nuts
  • 14 pieces provide coverage for typical header applications

ARP's Stainless 300 studs deliver exceptional durability in demanding exhaust environments where conventional fasteners fail due to heat cycling and corrosion. The compact 12-point nut design provides superior grip and accessibility compared to standard hex nuts, making installation and removal easier even in confined engine bays.

I got the part I ordered and will be having someone install it soon looks just fine and I love the chat feature as well.. thinking about buying brake shoes now.. a lot of savings

I ordered a new battery for my Harley. I wanted a battery that would last and be of good quality. I bought a Odyssey PC545 battery it stats stat it will last up to 8 years and is military grade. My package arrived quick and in good shape. My order number is #5600. Thanks

Autoplicity created a great shopping experience. It was very easy to find the parts I needed for the vehicle I needed. I will definitely use Autoplicity again!

I'll admit to being skeptical at first, but the price was worth the risk. Turned out to be one of the best online transactions I've experienced. Received item 3 days after purchaseing and the best price I found. And I looked hard! A+

Have to say I made a mistake about these guys they get the stuff shipped out quick.

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!

great prices and customer service was very helpful.
