    Notes:
    Blazers for 1981 had an aerodynamically restyled front end. The smoother new hood and fenders, together with a front bumper mounted air dam, were designed to improve fuel economy. A new grille continued the ice-cube-tray look with 16 taller openings running across the Blazer between the stacked square headlamps. A wide center horizontal molding - bright-finished with a bow tie in the middle - spanned the full width of the front end.

    Rectangular parking lamps/turn signals were placed in the new front bumper, directly beneath the headlamps.

    On the body sides, the belt-level feature line ran the length of the Blazer, and blended more smoothly into the fender edge at the front. Two-tone paint treatments were now separated at the lower perimeter feature line.

    Blazer 4x4 models had a new aluminum transfer case and automatic locking hubs.

    A new front quad shock package was available.

    Blazers featured a steel half-cab with an integral roll bar built into the steel front compartment roof and lock pillar structures.
