Advance Adapters started in 1971 starting 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. At the time, Advance Adapters also carried a full line of 4WD aftermarket accessories. Their next move was to venture into the manufacturing of additional components to compliment the already established adapter business. Headers, motor mounts, overdrives, and linkage brackets now became part of the Advance Adapters product line. In 1977, it was time to move out of Los Angeles and moved north, about 250 miles, to the small town of Paso Robles on the Central Coast of California. They started out occupying 10,000 sq.ft. of machining & warehouse with a 2,000 sq.ft. detached office, then added another 12,500 sq.ft. of warehouse space in 1984. This extra square footage was to house the winch business (Sidewinder Winch) that was purchased. In 1989, they realized that the winch business was more than they could handle alongside the heavy growing popularity of the adapter business. They sold this product line and decided to down-size and just do what they do best – adapters. In late 1995, the 4WD industry took a turn toward rock crawling. The product line offered many options for good, low ratio transmission swaps; however, the avid 4-wheeler was looking for more. Thus, they ventured into the ultra-low gear transfer case business (the Atlas Transfer Case). As of 1998, this nearly 44,000 sq.ft. facility houses all production, fabrication & administration. We have one of the most modern machining & manufacturing facilities found on the Central Coast.
