There was a time when trucks didn’t need to look smooth to be cool. Straight edges, bold grills, and unapologetic design choices made them unforgettable. And guess what? They still look incredible. These square classics haven’t faded; they’ve grown more iconic with every passing year. Want to see which ones kept the cool factor alive? Let’s jump into the lineup.

1976 Chevrolet K5 Blazer Chalet

Chevrolet’s 1976 K5 Blazer Chalet used a 400 cubic-inch small-block V8 and full-time 4WD via the NP203 transfer case. Additionally, a pop-up fiberglass camper shell and walk-through cab were built directly into the body. The strong K5 Blazer frame made off-grid use possible. Fewer than 1,800 units were ever produced.

1980 GMC Jimmy High Sierra

In 1980, GMC introduced the Jimmy High Sierra with a 350-cubic-inch V8 and an optional NP205 transfer case. It featured squared wheel arches for a boxy, trail-ready stance. The rear top could be removed entirely to give open-air capability. Because of its strength and design, it quickly became a top choice for early overland adventures.

1985 GMC K2500 Sierra Grande

Durable and easy to upgrade, the 1985 K2500 Sierra Grande included a 6.2L diesel V8 delivering 240 lb-ft of torque. Moreover, reinforced front leaf springs made handling heavy loads easier. As a result, square fenders allowed the simple installation of oversized tires. The package was completed with a tougher grille, built for demanding tasks.

1987 Chevrolet R10 Silverado

Chevrolet gave the 1987 R10 Silverado a more refined feel without losing its classic appeal. Throttle-body fuel injection was added to the 305 and 350 V8 engines, marking a first for GM trucks. Furthermore, flush side windows and a smoother grille improved airflow. As the final square body, it remains a smart and reliable choice.

1973 Chevrolet C10 Cheyenne Super 10

The 1973 C10 Cheyenne Super 10 received a bold makeover from Chevy, which incorporated slab-sided fenders and a recessed grille that started the square-body era. Under the hood, a 350 or 454 V8 paired with a Turbo-Hydramatic automatic transmission added power. Its upscale trim earned it the “Gentleman’s Truck” nickname among custom truck fans.

1984 GMC High Sierra Wideside

Powered by a 305 or 350-cubic-inch V8, the 1984 High Sierra Wideside came with both 4-speed manual and automatic transmission options. Adding to its sharp look, chrome moldings and a redesigned grille made a strong impression. Known for its reliability, fleet operators trusted this truck, while the bold paint made it easy to spot.

1983 GMC Sierra 1500 Diesel

GMC’s 1983 Sierra 1500 Diesel carried the early 6.2L diesel V8, rated at 130 horsepower. Power wasn’t the priority; instead, fuel efficiency won it fans among long-distance drivers. Diesel-specific badging and dual battery trays helped distinguish it. Modded versions later earned respect for handling tough towing demands with ease.

1981 GMC Sierra Classic 1500

A 305 or 350 V8 was under the hood of the 1981 Sierra Classic 1500, supported by GM’s Computer Command Control system for cleaner performance. New features included a flatter hood, squared dash, and chrome-rich styling. Dual fuel tanks extended its range, which makes this model a practical pick among vintage truck collectors now.

1978 Chevrolet K10 Scottsdale

Scalloped body lines and squared headlight bezels gave this truck a bold, refreshed look in 1978. Underneath, it packed a 350-cubic-inch V8 and GM’s part-time NP203 transfer case, boosting its off-road capability. Its rugged charm and reliable powertrain helped it gain popularity among lifted truck enthusiasts and trail builders alike.

1975 Chevrolet C30 Dually “Big Dooley”

The 1975 “Big Dooley” featured dual rear wheels and widened fenders for added stability on heavy hauls. Meanwhile, a 454-cubic-inch V8 paired with a TH400 automatic ensured dependable performance. Thanks to its wide stance and bold frame, this model became a top choice for slammed custom and hot rod builds.
