From 1976 to 1980, the CJ-7 came equipped with a Dana 20 transfer case, Dana 30 front axle (27- or 31-spline), and a 29-spline AMC 20 rear axle, while later years, Laredo packages added tachometer, chrome bumpers, tow hooks, and interior upgrades including leather seats and clock. In 1980, the Laredo was first fitted with an AMC 20 rear axle until mid-1986, when it was equipped with a Dana 44, and all 1980 and newer CJ-7s came with the Dana 300 transfer case.
