In this update, we’ll talk about several very interesting projects happening at AZ Diff in Phoenix, Let’s start with my 1973 Dodge Dart, that will soon be fitted with a newly built Chrysler 83/4” rearend with 3.73 gear and posi, to replace the stock [wimpy] 71/4”. The Dodge originally came with the slant six engine and that small rearend was just fine for that low horsepower engine, but this Dodge now sports a 300+ horsepower 340 cid V-8. The shop narrowed the beefier rearend and used the spring perches and other components from the original rearend. Several other special projects include a ‘66 Ford Falcon, that was fitted with a new 9” Ford rear with 3.50 gear and posi. It also got new Wilwood rear disc brakes, QA1 coil-overs and a 4 link suspension. A 1963 406 stroker small block powered Chevy Nova wagon that had been converted from 4 doors to 2 doors was at the shop and has been upgraded with a new 9” Ford rear, air-bags and a 4 link suspension. The shop also fabricated a new radiator core support. A ‘75 Chevy Blazer is being turned into a full blown drag truck with twin turbo LS power. Shown, is a photo of the newly built 9” Ford rearend and the completely inhouse custom built rear suspension with a ladder bar setup. The last special project, that’s just getting started, is a 1962 Corvette. The AZ Diff shop will be creating a complete new custom built C-4 type suspension for it. This will be a full custom build, including the LS based engine and transmission. In the main shop, several daily driver vehicles, a Dodge 2500 pickup, a Jeep, a Toyota Tundra and a Chevy Blazer were all receiving various upgrades and repairs. People may not know that Arizona Differential also does the type of special projects mentioned in this update.
