Automotive Racing Products, Inc. \u2013 better known as simply \u201cARP\u201d \u2013 can trace its roots back to 1968 when company founder Gary Holzapfel, who was then employed by an aerospace fastener manufacturer, sought to help some of his drag racer friends, Don Prudhomme among them, overcome their fastener-related engine reliability issues. The demand for premium grade head studs, and other fasteners, fueled the fledgling company\u2019s growth, which has necessitated expanding from its original backyard garage operation to a current footprint with some 200,000 square feet under-roof in multiple facilities for R&D, manufacturing, QC, warehousing, and administrative operations.<\/p>\n

[Editor\u2019s Note: This story originally appeared in DI #191, t<\/em>he 30 Under 30 Issue<\/em>, in November \/ December of 2024.]<\/p>\n

ARP remains a family-owned and operated business, with three generations (founder Gary, his son, Mike \u2013 the company president \u2013 and grandson Ryan) involved. The company\u2019s goal is to make the best possible products and proudly does everything in-house at its Southern California facilities \u2013 from forging and heat-treating to precision machining, packaging, and distribution.<\/p>\n

As an interesting aside, Gary\u2019s dad was a chef and instilled a love of fine food in his family. With a scarcity of good places to eat in the area, the company built a restaurant at the hub of ARP\u2019s manufacturing operations in Santa Paula. It\u2019s called \u201cHozy\u2019s Grill\u201d (the nickname bestowed upon the chef) and it\u2019s open to the general public. It\u2019s decorated in a racing theme, staffed by classically trained chefs, imports the highest quality meats, poultry, fish, and vegetables, and even carries an impressive \u201c2 Glass\u201d rating from the prestigious Wine Spectator<\/em>. It\u2019s well worth checking out at www.HozysGrill.com.<\/p>\n

From a drag racing standpoint, the motto of the long-time NHRA major sponsor (and sponsor off the newly-announced \u201c6-Second Club\u201d for Factory X competitors) is \u201cWorking together, we win races.\u201d As such, the company has developed strong working relationships with many of the sport\u2019s leading competitors, crew chiefs, and engine builders. ARP\u2019s in-house testing capabilities (which rival that of major Detroit automakers) are employed to develop new fasteners to solve issues that racers are having.<\/p>\n

The company also provides free torque wrench testing services at NHRA national events. Over the years they have seen many competitors come with torque wrenches that were off by as much as 30-40% or more. Since the effectiveness of a fastener depends on it being properly preloaded, ARP urges racers to make sure their torque wrenches are properly calibrated.<\/p>\n

\"\"<\/figure>\n

Another potential problem lies in how the fastener is lubricated, as inconsistencies in the lubricant itself can lead to a condition known as \u201cpreload scatter.\u201d That\u2019s why the company invested considerable effort and resources to develop ARP Ultra-Torque Fastener Lubricant\"\u2122\". It\u2019s far superior to oil, moly, EPL, in consistency and laboratory-proven to deliver 95-100% of the desired preload on the first, and all subsequent pulls on the torque wrench.<\/p>\n

It\u2019s important to understand that the metal used in manufacturing fasteners comes in four grades: commercial, aircraft, CHQ, and SDF (seamless, defect free). ARP employs only the two best \u2013 which are far superior to \u201caircraft\u201d quality. Another metallurgical factor of importance is the alloy. For critical engine fasteners, like head and main studs\/bolts and connecting rod bolts, ARP uses five types of alloys (8740 chrome moly, ARP2000\"\u2122\", Custom Age 625+, L19, and ARP 3.5\"\u2122\") which range from a 200,000 psi nominal tensile strength to 280,000 psi. Accordingly, you can get fasteners suited for applications that range from a normally aspirated gas-burning engine to a supercharged nitro-guzzler.<\/p>\n

\"\"<\/figure>\n

There is also much to be said on how<\/em> a fastener is manufactured. ARP does its own heat-treating in-house, with studs placed in racks \u2013 not thrown into a bin \u2013 to assure accurate through-hardening. Threads are rolled (not cut) after<\/em> heat-treating to provide vastly superior fatigue strength and meet AS8879D specifications to ensure the best possible thread engagement. All operations are the best possible \u2013 not the cheapest.<\/p>\n

Over the years ARP has developed some 5,500-plus fastener kits that cover everything from an old flathead Ford to the latest Chevy LS\/LT, Ford Coyote and Godzilla, and Chrysler Gen III Hemi applications. The company manufactures a wide variety of accessory bolts and studs that are made from polished stainless steel or black oxide finished 8740 chrome moly. Both are nominally rated at 180,000 psi tensile strength \u2013 fully 20% stronger than Grade 8 hardware.<\/p>\n
