Product Details

The ARP 154-4104 head stud kit is engineered specifically for 1949-1953 Ford Flathead V8 engines equipped with Offenhauser aftermarket cylinder heads. This premium fastener kit delivers the superior clamping force and reliability that professional engine builders demand for high-performance and racing applications.

Premium Construction and Manufacturing:

  • Manufactured from premium grade 8740 chromoly alloy, rated far superior to standard aircraft quality materials
  • Each stud is precisely heat-treated to 200,000 psi tensile strength in vertical racks for complete and uniform heat penetration
  • Centerless ground to exacting tolerances for near-perfect concentricity, ensuring cylinder heads and gaskets align easily during installation
  • Thread rolled after heat treatment for approximately 1000% better fatigue strength compared to pre-heat-treat threading
  • Black oxide finish provides excellent corrosion and wear protection

Kit Includes:

  • Hardened parallel washers for uniform load distribution and accurate torque readings
  • Hex head nuts for secure installation

ARP has been the industry leader in high-performance engine fasteners since 1968, and this head stud kit represents the same engineering excellence trusted by top professional engine builders worldwide. The precision manufacturing process ensures your Flathead engine's cylinder heads remain securely fastened under extreme loads and temperatures.

quick

The product reviews given are not specific to the item I was interested in ordering. However, my order was processed the same day it was received. One of the two items shipped the same day and the other was shipped the following day. Both items were received within four days from the date ordered. Packaging was sufficient as neither item was damaged. Both items were exactly what was described on the website. Pricing, (including shipping) was better than any other retail or online price that I could find.

Easy

efficient.

A real pleasure doing business with you guys. I ordered over the phone and received great service and the correct product in a very timely matter. Very pleasant transaction with no hassles! Thank You so much. John W.

Best price I could find on the Internet can't go wrong with saving money

fast and easy.

Ordered Friday and received the shipment Tuesday. Excellent price. The product was exactly as ordered and arrived in good condition. The checkout process at autoplicity.com is incompatible with nonmainstream browsers. No joy even with java, javascript, referrer logging and cookies all enabled. Finally I placed the order over the phone. Ten minutes later I received acknowledgments for two identical orders, 8961 and 8965. I phoned and asked them to cancel one of the duplicate orders. Four hours later I receive an e-mail saying my order 8961 was canceled for one of four possible reasons, none of which was "We canceled your order that was accidentally duplicated." So I had to phone again (phone is more effective with autoplicity than e-mail or chat) to see whether they had canceled one or both orders. The excellent price was offset by the communication hassle. If you prefer not to use IE or Thunderbird or Chrome, then skip the checkout hassle by placing your order by phone.

I don't typically review online stores, but Autoplicity was awesome! Shipped ridiculously quickly and my H&R springs were at my house two days after I ordered. Awesome, and for a great price. Thanks guys
