They say that to be successful; you must identify a need and satisfy it. Back in 1968 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 Mr. Holzapfel called upon his many years of fastener-making experience for a leading aerospace subcontractor and founded ARP Automotive Racing Products.
Since its founding years, ARP has grown from what was a backyard garage workshop into a highly diversified fastener manufacturer. Automotive Racing Products / ARP now runs five production facilities in Southern California with a combined area of more than 200,000 square feet. These include forging, machining, finishing, and packaging/warehousing facilities in Santa Paula and Ventura, California. ARP now manufactures thousands of part numbers that cover virtually every fastener found in an engine and driveline.
ARP offers the highest quality American Made fasteners with multiple strengths for use in OEM replacement parts to exotic specialty hardware.
Automotive Racing Products achieved the ISO 9001:2008 and AS9100 registration in 2009. Since that time ARP has maintained these certifications which represent ARP's unwavering dedication to the production of the highest quality fasteners available in the market today. ARP is continuously improving its internal processes to deliver the highest-quality high-performance fasteners available to its customers. You should also know that the entire line of ARP bolts and fasteners is superior to those from other manufacturers. Especially in the area of fatigue strength. Testing has shown that the ARP fasteners have up to ten times the fatigue strength of different fasteners and bolts. Make the most of your budget and rely on ARP bolts and fasteners to get the job done. You'll find the ARP name proudly stamped on each bolt as your assurance of quality. KLM Performance is proud to offer the ARP product line to our customers.
