Advance Adapters
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.

The Dana Model 300 transfer case has developed a reputation of being strong and durable. The only weakness is the output shaft. Advance Adapters has put together a kit to upgrade from the stock 1-1/8" diameter 26 spline output to a stronger 1-3/8" 32 spline output shaft. This kit includes new output shaft, rear tailhousing, yoke, bearings, seals and other necessary hardware.

Mounting your twin stick shifter in your buggy just got a little bit easier! Advance Adapters now offers a cable-shifter for the Atlas transfer case. The new shifter assembly allows for virtually any positioning of the shifter levers. Those with rear-engine buggies or Jeep’s with consoles will now have an easier time reaching the shifters. The rugged cable assembly and shifter mount will withstand the brutal punishment of competition rock crawling.
