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.

1978 the instrument panel trim and nameplate were changed. There was a deluxe
instrument panel option with black-textured center section for Custom Deluxe models, and
bright brush finish for Cheyennes.
Also new was a redesigned rear compartment entry/exit
system, a new rear folding seat, and a flatter floor panel behind the seat for extra leg
room. The frame was changed to position the body mounts outside of the frame to
allow for the new rear seat design.

| Notes:
The
1973 Blazers were radically changed in appearance from previous models. Major
styling features consisted of curved side glass, doors that opened into the roof line, and
the elimination of roof drip rails. Running along the belt line was a sculptured
cove. Along with the very wide and flat load box, it gave the new model very clean
and distinctive lines. A wider interior featured a powered, flow-through ventilation
system. A redesigned dash, with all instruments and controls placed in a
semi-circular cluster within easy reach and view of the driver, was adopted. The
steering wheel was reduced in diameter and the wheelbase was lengthed from 104 to 106.5.
The
1973 Blazers had a full-time 4x4 system.
Those with the Cheyenne trim had a chrome circle on the rear fender.
The tailgate came two ways, with the open utility it was like the Fleetside Pickup's
gate and when the optional hardtop was ordered, the gate had a manually-operated roll-up
window, this eliminated the lift-gate that had been used in older tops.
New energy absorbing steering column.
The Blazer's single-unit body was joined to a heavy channel steel frame and had a
completely removable fiberglass top. |

Chevrolet production records show a model number and listing for a 4x2 Blazer, but
indicate that none were built in this model-year.
