At $92K, This ’72 GMC Suburban Is Ready for What’s Next GM designers nailed it when they penned the 1967–1972 C/K “Action Line” of trucks. This generation spawned the K5 Chevy Blazer and its GMC Jimmy counterpart, creating what would become one of the classic truck market’s favorite full-size sport utility vehicles. Sport truck fans have long appreciated the regular-cab short-bed trucks of this era, especially the rear-wheel-drive models that featured trailing-arm suspension and coil springs in the rear. The largest passenger variant offered, the Suburban, also benefited from GM’s star-studded ’60s design team, making the three-row SUV fit into the lineup without looking like an afterthought. The Suburban, like the rest of the body styles offered, has been embraced by collectors. We found this example, a 1972 GMC K2500 Deluxe that recently sold at Bring a Trailer for $91,875, and can’t get enough of it. What’s not to love about this brawny family hauler? The Suburban of this era has gorgeous lines and was available with either a tailgate and liftgate or, as this K2500 was optioned, with barn doors that make it a bit easier to reach into the ample rear cargo area. The medium bronze paint, applied in 2010 when the big wagon was treated to a rather thorough restoration, looks to be in great condition. And the contrasting white top matches the 16-inch steelies, which are dressed with factory caps over manually locking hubs and shod in BFGoodrich All-Terrain T/A tires. Those All-Terrains have been a favorite of off-roaders since their 1976 debut, so they’re a great choice for a classic ’70s 4×4. The mild suspension lift and 285/75R16 tires give the SUV an improved stance and don’t take away from its vintage vibes. Modern factory 4x4s have made 35- and even 37-inch tires seem normal, so it would be easy to forget that a Suburban wouldn’t have come with 33-inch tires from the factory. Complementing the white top and wheels is a parchment interior with three rows of seating. With just one rear door, on the truck’s curbside, the second-row seat is offset toward the driver to allow access to the back, where an identical bench seat is centered between the rear wheel wells. Even with a white top, the Suburban has ample glass and would get very hot inside. Thankfully, this one’s equipped with front and rear air conditioning, with a roof-mounted plenum that helps divert cool air to the passengers sitting in the third row. The interior features door panels with embossing that matches of the vinyl upholstery. Trucks from the ’70s were more utilitarian and certainly nothing like the luxurious Yukon XL Denalis that GMC is building today. Still, this Custom trim level, the base trim offered in 1972, is a 3/4-ton 4×4 model with A/C and an automatic transmission, representing a well-optioned version of the 1972 Suburban. Its build sheet notes it’s equipped with a Custom Deluxe package, which should be different from the Chevrolet trim level of the same name. Unfortunately, GMC brochures from the era are harder to come by. One curiosity of this particular truck: Shown above are the inside of the driver’s and passenger’s front doors. Which part of these is not like the other? Somewhere in its 54 years of existence, this Suburban appears to have had a replacement passenger door installed from a 1967–71 Suburban or pickup. In 1972, all Chevy and GMC Action Line trucks received an extra screw to anchor the vent window. It’s visible here on the top forward edge of the driver’s side door. The 175-horsepower 350-cubic-inch small-block was the middle V-8 option in the 1972 GM truck lineup, between the 135-hp 307 small-block and the 210-hp 402 big-block. Bring a Trailer/JNorVintage Things are clean and simple under the hood, where a rebuilt Chevy 350 small-block looks the part of a ’70s workhorse. The V-8 also received new accessories when the rest of it was re-machined and reassembled in 2024. It’s bolted to a three-speed Turbo 400 automatic that sends power to both axles by way of the tough and reliable NP205 transfer case. The 3/4-ton Suburban uses a Dana 44 axle up front and an Eaton axle, complete with limited-slip differential, in the rear. A bit of an axle oddity, the Eaton features both an inspection cover and a removable third member. Unlike later transfer cases that often use an aluminum case and a wide chain to get power to the front axle, the venerable NP205 uses a cast-iron case and transmits torque exclusively through gears. Its only shortcoming is its low range, which is 1.96:1. Rock crawlers typically prefer much more torque multiplication and lower crawl speeds, but with a 127-inch wheelbase and an overall length of about 18 feet, this bruiser is really not cut out for the Rubicon Trail, anyway. The Suburban design has some thoughtful touches, and it’s not just an enclosed pickup or lengthened Jimmy. Take a look at the rear panel, for example, as the trailing edge of the Suburban cants forward and the unique taillights emerge from the body just slightly. Although this truck’s $91,875 sale price is an impressive result, it’s not the highest we’ve seen for a 1967–72 Suburban. An LS-powered 1968 Chevy Suburban restomod sold for $308K at Barrett-Jackson’s 2022 Scottsdale sale, while a closer-to-stock, restored 1970 GMC brought $110,000 at Barrett-Jackson Palm Beach in 2022. This sale is still far above what we’d expect for even a #1 (concours) 1972 Suburban K2500. Chalk it up to a well-done restoration that keeps things factory-appearing while not being over-restored to the point that it loses its utility. This beautiful Suburban looks like it’s ready for another 50 years of service. Its rebuilt small-block certainly should offer plenty of reliable power as well. Hopefully, there are plenty of camping excursions and road trips in its future, and its new owner appreciates it as much as its previous owners clearly have.
