Advanced Adapters, located in the Southern California city of Paso Robles, started in 1971 by producing a single adapter which mated a Muncie car 4-speed to a Jeep Dana 18 transfer case. The company has expanded since then to include headers, motor mounts, overdrives and linkage brackets. In 1995, Advanced Adapters expanded their product line once again to include ultra-low transfer cases. Advanced Adapters does all of its product design and manufacturing in Paso Robles, California. The U.S. made design and production is for Advanced Adapters' full line of replacement parts, not just the adapter line.The humble beginning of Advance Adapters started in 1971. Located in an alley off Woodruff Boulevard in Downey, CA., the business started with a single adapter mating a Muncie car 4-speed to a Jeep Dana 18 transfer case. The popularity of this kit grew, and Advance Adapters soon found itself venturing into a variety of vehicles and adapters. As the product line grew, so did the facility. We soon found ourselves occupying a store front located directly on Woodruff Blvd. In these early days, Advance Adapters also carried a full line of 4WD aftermarket accessories. This furthered the growth of the company and exposed us to the ever-growing need for additional adapting components.
