Product Details

The ARP 100-1412 is a premium header stud kit designed for small block engines, featuring 3/8" diameter studs with 1.670" length and a corrosion-resistant black oxide finish. These hex header studs are manufactured from heat-treated 8740 chrome moly steel, providing exceptional strength and reliability in high-temperature exhaust applications.

Key Features:

  • Heat-treated 8740 chrome moly steel construction rated at 170,000 psi tensile strength
  • Black oxide finish for corrosion resistance and durability
  • 3/8" diameter x 1.670" length studs optimized for small block applications
  • Hex head design for secure installation
  • Complete kit includes studs, premium-quality washers, and hex nuts
  • Engineered to withstand extreme exhaust temperatures and vibration
  • Significantly stronger than standard Grade 8 hardware

ARP header studs are the professional's choice for exhaust system installation, providing superior clamping force and resistance to thermal cycling. The precision-machined threads and high-quality materials ensure reliable performance in street, strip, and racing applications where header security is critical.

Best price I could find on Autolite HTO plugs highly recommended

Good

The price was good. The Web site is easy to navigate. It's an added bonus of free shipping.

Best price!

Very easy to place order

Prices are among the lowest around. Had a change with my order. Customer support team was quick to respond to emails and make corrections. Will order from Autoplicity again.

everything was good thanks

Great price, good e-mail communication and fast shipping. Positive experience with Autoplicity so far.

Thanks

Prices are great on this site. The layout and checkout process are easy to use; Google checkout is definitely a plus. Shipping could be a little faster, especially if they had drop ships from their supplies for items not currently in stock. Overall good service and no problems.

I bought this item for my fiance and he loves it! He was completely happy with the price we paid...

Good site easy to search for and find parts. The lowest prices on almost every part I have been able to find for my truck.
