More About ATI Performance Products

ATI Performance Products is a company founded on innovation, precision and service. ATI and Jim Beattie are synonymous in the field of drag racing. It is common to find ATI equipped vehicles winning races throughout the United States. However, this tremendous success didn't happen overnight. ATI Performance Products is the creation of over 40 years of transmission and performance component manufacturing and racing experience. In the early 1960's, Jim Beattie, ATI's president and owner, left the Navy and opened a general transmission rebuilding shop that has grown into one of the largest suppliers of quality high performance transmissions, torque converters and driveline components in the industry. Jim further enhanced his new company's image by competing as a Sportsman drag racer in the '60's and as the owner and sponsor of the immensely popular original Black Magic Fuel Funny Car, a crowd favorite in the mid-70s. Today, ATI manufactures a multitude of high performance parts including Competition Transmissions, Treemaster Converters, Torsional Super Dampers, Compu-Flow Valve Bodies, Flexplates, and Adapter Kits as well as a wide variety of performance enhancing internal components. ATI's commitment to racing has allowed the company to maintain a prominent position on the cutting edge of high performance component design and manufacturing. ATI features one of the most advanced machine shops in the industry with a plant equipped with some of the finest CNC lathes, milling machines and machining centers available. ATI has maintained a close relationship with racers and racetracks, no matter what the class, bracket or size of the track. As a major sponsor of the NHRA, IHRA and ARCA, Jim and the entire ATI staff have made a strong commitment to the sport of racing and the tradition of providing the finest performance parts in the industry. We feature ATI Super Dampers and ATI Timing Pointers at low everyday prices!
