CHA Industries, Inc. DBA ProActive Gears started in 1984 in Chicago, IL as a direct importer and wholesale distributor of aftermarket transmission gears. Through strong relationships with overseas manufacturers, the company was able to bring a high-quality product to the aftermarket as a cost-effective alternative from the OEM options. Over the years our product line has broadened and diversified to include a vast variety of differential, transfer case and manual transmission products. We have also added a second distribution point to cut down on shipping times for our customers in the Los Angeles area. Our company relies on the reputation of having the highest quality products available in the aftermarket directly imported by us and our goal is to continuously provide this high level of quality and service to our customers.
Thank you for visiting our site, and hopefully we can supply you with our great product line. If you have any questions give us a call, you will always reach a live sales representative in seconds.
