AZ Diff. does just about anything related to your car, Jeep or pickup differential, driveshaft, suspension, or brakes. Here are some recent examples; Up on a lift is a really nice ‘67 Chevy Nova, that’s been fitted with a fresh built 12 bolt positraction rear end. The Nova is also getting a new set of Cal-Tracs rear springs and a complete 4 wheel disc brake conversion kit by Wilwood. Up on another lift is the bare frame from a 1959 Chevrolet car. The shop has completely stripped it down and cleaned and refurbished it and then had it fully powder coated. Out in the Fabrication Shop, a 1986 Jeep Scrambler is in the final stages of a complete in-house custom build. They installed a GM 5.3 liter LS V-8 engine and 4L60 AOD 4×4 transmission. The rear differential is now a 9” Ford and the front diff is a DANA 44. The Jeep also got new coil-overs and bypass shocks front and rear. They also created a full roll cage and custom tire carrier. The steering was upgraded with a new hydro-assist system. Several other modifications are now part of this awesome Jeep and it now rides on 40” tires. Doing repairs and upgrades on Jeeps, pickup trucks and other 4×4 vehicles is a big part of the Arizona Differential business. Call them at 602-272-4600 to talk about your vehicle. Please mention Roddin’ & Racin’ when you call.
