Arizona Differential has been in business for well over 25 years doing just about anything and everything related to your car, truck, and 4 x 4 vehicle’s differential, driveshaft, and suspension. They do a lot of custom modifications and upgrades, including full custom differential builds and suspensions. On any given day, the shop will have at least a few pickup trucks up on one of their heavy-duty vehicle lifts, receiving a differential rebuild or maybe a gear ratio change, or maybe it’s being converted to a positraction type of system, or maybe it’s just getting new wheel bearings or U-joints that were beginning to make noise. There are several examples of trucks and a Jeep shown here, that are all having service, repairs, or upgrades. Also shown is my 1970 Camaro, which they have custom built and installed a 9” Ford rearend with 3.23 gear ratio, positraction and completely hooked up the Ford drum brakes to the Camaro’s brake system. While at AZ DIff, they also removed the Camaro’s original 3 speed manual transmission & shifter and installed my Turbo 400 3-speed automatic transmission and a new B & M gate shifter and a new Hughes Performance 2500 stall torque converter. The new transmission required some modifications to the transmission cross member and a new mini starter was required. The Camaro’s driveshaft also required modifications, including a new slip yoke to fit the Turbo 400 motorhome transmission. New heavy-duty Spicer U-joints were also used on the computer spin-balanced driveshaft. My 1970 Camaro is a great example of the custom work that AZ Differential has been doing for many years.
