ARP Automotive Racing Products

ARP is the undisputed world leader in automotive fasteners. ARP offers a wide variety of bolts, studs, nuts, and fasteners specifically designed for high-performance machines. These range from quality OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR and NHRA drag racing and marine applications. Their engineers ensure that every piece will outperform any other fastener on the market today. That's why so many top engine builders rely on ARP racing products to hold their engines together.

It all started in the early 1970s, when racing enthusiast Gary Holzapfel saw that many of his friends’ broken engines were caused by fastener failure. At the time, there were no commercially available studs and bolts up to the challenge. So Holzapfel called upon his many years of fastener making experience for a leading aerospace subcontractor and founded ARP (Automotive Racing Products). In the ensuing years, they have grown from what was literally a backyard garage workshop into a highly diversified manufacturer with seven operational entities in Southern California with a combined area in excess of 200,000 square feet. These include facilities for forging, heat-treating, machining, thread rolling, shot-peening, metal finishing as well as packaging/warehousing in Santa Paula and Ventura, California.

There are several important elements in the production of specialty fasteners, not the least of which are materials, design, and manufacturing. Extensive backgrounds in mechanical engineering, metallurgy, and stress analysis complement the extraordinary steps taken to produce the very finest products on the market today. ARP's product line contains thousands of part numbers and has expanded to include virtually every fastener found in an engine and driveline. Today's critical diesel fasteners such as head studs, main studs, connecting rod bolts, and driveline hardware have been designed stronger than ever before to handle the extreme loads.

OE-head bolt stretching has been a problem for many diesel truck owners. This applies to both those who are into performance as well as owners of stock vehicles. ARP’s head stud kit for diesel truck applications provides the ideal solution to a common problem. Replacing the factory Torque-To-Yield (TTY) head bolts with upgraded ARP Head Studs is a popular upgrade for many Ford 6.0L & 6.4L Powerstroke owners. The Super Duty and Excursion are well known for stock head bolts that can stretch and head gasket failures. ARP studs can be an excellent investment for any high-performance Dodge/RAM Diesel, Chevy/GMC Diesel, and Ford Diesel. Head Studs are offered in a standard Diesel Head Stud Kit or Diesel Custom Aged 625+ Head Stud Kit. The Custom Aged 625+ studs are the ultimate head stud and are ideal for high-horsepower and competition applications.

No another company in the world is as focused on building superior quality fasteners for all forms of racing and non-racing applications as ARP. Upgrade your Ford F-250/350 Super Duty, Dodge Ram 2500/3500, or GM Silverado/Sierra 2500HD/3500HD with ARP fasteners from XDP!
