Since then it has received extensive work to the transmission, axles, suspension, brakes, cooling system, fuel system, and interior audio. The green and white Cheyenne Super presentation remains, but 35-inch tires, a 6-inch lift, and a full-floating 14-bolt rear axle now make the mechanical specification as noticeable as the paint.1972 Chevrolet K20 Cheyenne SuperBring a TrailerWhat it's worth right nowThe current Classic.com 1972 K20 market data shows how wide this market has become. A 4,000-mile Cheyenne/Super sold for $57,500 in August 2026, a 45,000-mile Cheyenne brought $66,000 in June, and a modified Cheyenne/Super reached $88,000 in May. Hagerty records a 16,000-mile 350-powered K20 selling for $42,000 in January 2026 and lists $29,200 for a #3 good-condition 350 Fleetside. This truck itself sold for $46,000 on BaT in July 2024.1972 Chevrolet K20 Cheyenne SuperBring a TrailerThe work completed since that sale matters. A rebuilt transmission, 14-bolt axle, 4-wheel discs, suspension overhaul, fuel-tank relocation, new tires, cooling work, and substantial audio installation add usability and presentation. Against that sit prior rust and body repairs, unknown total mileage, no air conditioning, and a small power-steering leak. Fair value lands between $62,000 and $75,000.Condition and detailsThe body received rust repairs, replacement fenders, bed, and tailgate before being repainted green and white under prior ownership. The current owner later replaced the grille, taillights, windshield seals, and door seals. The fuel filler is now hidden behind the hinged left taillight housing. New 35×12.50 BFGoodrich All-Terrain T/A tires sit on 17-inch KMC wheels.1972 Chevrolet K20 Cheyenne SuperBring a TrailerThe suspension was redone with a 6-inch Skyjacker lift, rear blocks, replacement ball joints, and related steering work. Four-wheel disc brakes replace the previous front-disc and rear-drum arrangement, with a replacement master cylinder, proportioning valve, brake lines, and parking-brake cable. The seller notes a small power-steering fluid drip.1972 Chevrolet K20 Cheyenne SuperBring a TrailerAdvertisementAdvertisementInside, the heated bench seat combines green vinyl with houndstooth cloth, while the audio system uses a RetroSound Bluetooth head unit, Morel speakers, and JL Audio amplifiers, digital signal processing, and 3 10-inch subwoofers. The fan-speed lever is missing. Mechanical work includes a rebuilt automatic transmission, 14-bolt full-floating rear axle with 4.10 gearing, rebuilt front axle, resealed transfer case, replacement radiator, engine mounts, oil-pan gasket, fuel system components, and 170-amp alternator.1972 Chevrolet K20 Cheyenne SuperBring a TrailerThe offerSpecificationDetailMakeChevroletModelK20 Cheyenne SuperYear1972Mileage30,000 miles shown, true mileage unknownEngineModified 350ci V8PowerNot stated for the modified engineTransmission3-speed automaticDrive typeFour-wheel driveTransfer caseDual-rangeRear axle14-bolt full-floating, 4.10 gearingExterior colorGreen and whiteInterior colorGreen vinyl and houndstooth clothCurrent bid$58,500 with 4 days remainingInterested in this truck? View the listing here.What makes the K20 uniqueThe K20 sat above Chevrolet's half-ton K10 as the 3/4-ton 4-wheel-drive member of the second-generation C/K family. By 1972, Chevrolet had spent 6 model years refining the body style that arrived for 1967, and the final-year trucks gained much of their appeal from the combination of cleaner styling and work-focused hardware. The K20's heavier-duty chassis and axles separated it mechanically from the more common K10.1972 Chevrolet K20 Cheyenne SuperBring a TrailerCheyenne Super trim put more emphasis on comfort and appearance, adding an upscale layer to a truck still intended to work. That combination is why well-finished K20s can command serious money today. This example takes the idea further with modern brakes, lifted suspension, a full-floating rear axle, relocated fuel tank, upgraded audio, and a cammed 350, sacrificing factory specification for a truck designed to be used rather than preserved.My takeThe $46,000 purchase price from 2024 is useful because it shows exactly where this truck started before the latest round of work. The upgrades since then are substantial and focused on the parts that affect how it drives, stops, and handles. Prior body repairs and unknown mileage keep it out of preservation-grade territory, but that is not what this build is trying to be. The $62,000 to $75,000 range fits its current specification.AdvertisementAdvertisementDisclaimer: This post is for informational purposes only. We are not a dealership or broker.
