Auto Tech

We have been in the Instrument Repair, Manufacturing and Service field since 1954. Locally we service, repair and certify Law Enforcement, U.S. Border Patrol and most cars, trucks and heavy equipment vehicles and instruments. Please visit us when you're in sunny Tucson. We've been in business at the same location for many years. This website was designed to inform you of our vast computerized inventory of speedometer products dating from 1917 to present. Including parts that are no longer available from across the nation. We make custom speedometer cables and repair original cables also.
