The period from 1970 to 1975 represents a golden era for Chevrolet trucks, encompassing the tail end of the iconic "Action Line" C/K series (1967-1972) and the exciting debut of the revolutionary "Square Body" generation (1973-1987). These trucks have transcended their original utilitarian purpose to become highly sought-after classics, admired for their rugged durability, timeless aesthetics, and immense versatility. Whether you’re a seasoned collector, a first-time classic truck owner, or someone looking for a unique project, the market for 1970-1975 Chevy trucks offers a vast array of options, each with its own story and potential. This comprehensive guide will navigate the nuances of these beloved machines, providing insights into what makes them special, what to look for, and how to make a smart purchase.
The Enduring Appeal of Two Iconic Generations
1970 To 1975 Chevy Trucks For Sale: A Comprehensive Buyer’s Guide
The 1970-1975 timeframe is unique because it bridges two distinct and highly popular Chevrolet truck designs. Understanding these differences is key to appreciating their individual characteristics and market appeal.
The "Action Line" (1970-1972 C/K Series)
The second-generation C/K series, affectionately known as the "Action Line" or "Glamour Pickups," began in 1967 and concluded with the 1972 model year. These trucks are celebrated for their sleek, low-slung profiles, which gave them a car-like appearance while retaining robust truck capabilities.
- Design Highlights: Featuring clean lines, a wider and lower stance, and a distinctive front fascia with a prominent grille, the 1970-1972 models perfected the look. The ’70-’72 trucks are often distinguished by their updated grilles and subtle trim changes.
- Key Models: The C10 (half-ton, 2WD) is arguably the most popular, known for its comfortable ride and performance potential. The C20 (three-quarter-ton, 2WD) and C30 (one-ton, 2WD) offered increased hauling capacity. For off-road enthusiasts, the K10 and K20 (4WD variants) provided rugged capability. The K5 Blazer, introduced in 1969, became an instant icon, blending SUV utility with convertible fun.
- Engine Options: A wide range of inline-six and small-block V8 engines were available, including the venerable 250 ci I6, 307 ci V8, 350 ci V8, and the larger 396/402 ci big-block V8, offering plenty of power for the era.
- Appeal: Their classic hot-rod aesthetic makes them prime candidates for customization, from lowering and performance upgrades to full show-truck restorations.
The "Square Body" (1973-1975 C/K Series)
The third-generation C/K series, universally known as the "Square Body," debuted in 1973 and represented a radical departure in design and engineering. These trucks introduced a more modern, angular, and functional aesthetic that would define pickup trucks for decades.
- Design Highlights: The "Square Body" name comes from its boxier, more utilitarian shape, prioritizing interior space, aerodynamics, and structural integrity. Key innovations included a double-wall steel construction for the bed, a larger cab for improved comfort, and improved ventilation.
- Key Models: Like their predecessors, the C10/K10, C20/K20, and C30/K30 remained the core offerings. The K5 Blazer continued its evolution, becoming more refined. The Suburban also adopted the "Square Body" design, offering extensive passenger and cargo room.
- Engine Options: The engine lineup continued with reliable inline-six and small-block V8s (e.g., 250 ci I6, 350 ci V8), with big-block V8s (e.g., 454 ci) available for heavy-duty applications. The early ’70s also saw the beginning of emissions controls, which slightly impacted performance on later models within this range.
- Appeal: Their robust build, spacious interiors, and relative abundance make them excellent candidates for daily drivers, work trucks, or more budget-friendly restoration projects. The "Square Body" trend has surged in recent years, making them increasingly popular.
What to Look For: Key Considerations Before Buying
Purchasing a classic truck requires a discerning eye. Here’s a checklist of critical areas to inspect, regardless of the year:
- Rust: This is the primary enemy of vintage vehicles.
- Common Spots (Action Line): Cab corners, rocker panels, lower fenders, door bottoms, bed floors, bed sides above the wheel wells, inner fenders, and frame rails (especially near spring hangers).
- Common Spots (Square Body): Similar to the Action Line, but also check the cowl area (under the windshield), front cab mounts, and the floorboards near the footwells.
- Solution: Surface rust can be managed, but extensive structural rust (frame, cab supports) is costly to repair and can compromise safety.
- Engine & Drivetrain:
- Engine: Check for leaks (oil, coolant), excessive smoke from the exhaust (blue for oil, white for coolant), strange noises (knocking, ticking), and proper idling. Look for signs of neglect or recent, shoddy repairs.
- Transmission: For automatics, check fluid color and smell, and test for smooth shifting through all gears. For manuals, check clutch engagement and gear grinding.
- 4WD (K-series/Blazer): Engage 4WD and test the transfer case and front differential. Listen for unusual noises.
- Practical Advice: A pre-purchase inspection by a mechanic familiar with classic vehicles is highly recommended.
- Interior Condition:
- Dash: Cracks are common due to sun exposure.
- Seating: Check for rips, tears, and worn upholstery.
- Gauges & Electrical: Test all lights, turn signals, wipers, heater/AC (if equipped), and gauges. Wiring issues can be frustrating to diagnose.
- Tip: While interior components are often replaceable, factor the cost into your budget.
- Suspension & Steering:
- Look for worn ball joints, tie rods, control arm bushings, and leaf springs. Excessive play in the steering wheel indicates worn components.
- Solution: These are common wear items and generally straightforward to replace, improving ride quality and safety.
- Documentation: Always ensure the truck has a clear title that matches the VIN (Vehicle Identification Number) on the truck. Any service records or restoration receipts are a huge bonus.
Types and Configurations: Finding Your Perfect Chevy Truck
The variety of options available during this era means there’s a Chevy truck for almost every need and preference.
- C-series (2WD) vs. K-series (4WD): The "C" denotes two-wheel drive, ideal for street cruising, hauling, and lighter duty. The "K" signifies four-wheel drive, perfect for off-roading, adverse weather, or heavier work.
- Half-ton (C10/K10), Three-quarter-ton (C20/K20), One-ton (C30/K30): These designations refer to the truck’s payload capacity. Half-tons are typically preferred for daily driving and light hauling due to their smoother ride, while three-quarter and one-tons are built for heavy loads.
- Body Styles:
- Short Bed (SWB): Typically 6.5 feet, popular for their sportier look and easier maneuverability.
- Long Bed (LWB): Usually 8 feet, offering maximum cargo capacity.
- Fleetside: The most common bed style, with smooth, straight sides.
- Stepside: Features external rear fenders and a step behind the cab, offering a classic, distinctive look. Less common and often more sought after.
- Suburban: A full-size SUV offering ample seating and cargo space, available in both 2WD and 4WD.
- K5 Blazer: A two-door SUV with a removable top (full removable top on 1970-1975 models), highly desirable for its versatility and unique styling.
- Trim Levels: From basic "Custom" or "Scottsdale" models to more luxurious "Cheyenne," "Cheyenne Super" (Action Line), or "Silverado" (Square Body) trims, which included more chrome, upgraded interiors, and additional comfort features.
Restoration vs. Driver: Understanding the Market
The condition of a 1970-1975 Chevy truck greatly impacts its price and your commitment.
- Project Trucks: These are typically non-running or heavily rusted vehicles requiring extensive bodywork, mechanical overhaul, and interior refurbishment. They are the most affordable upfront but can quickly become money pits without careful planning. Ideal for those with significant mechanical and bodywork skills, or a generous budget for professional help.
- Daily Drivers: These trucks are in decent running condition, pass inspection, and can be driven reliably. They might have some cosmetic flaws, minor mechanical issues, or need ongoing maintenance. They offer a balance of affordability and immediate enjoyment.
- Show Trucks/Restored: These are vehicles that have undergone professional, frame-off restorations or highly meticulous rebuilds. They are in pristine condition, often exceeding original factory standards, and command the highest prices. They are often investments or showpieces.
- Modified Trucks: This category includes vehicles with modern engine swaps (e.g., LS swaps), updated suspensions, custom paint, or interior upgrades. Their value depends heavily on the quality of the modifications and the builder’s reputation.
Where to Find These Classic Trucks For Sale
The market for 1970-1975 Chevy trucks is robust and diverse.
- Online Marketplaces: Websites like eBay Motors, ClassicCars.com, Hemmings, and Bring a Trailer (for higher-end or unique examples) are excellent starting points. Facebook Marketplace and dedicated classic truck groups on social media are also treasure troves.
- Local Classifieds & Dealerships: Check local online classifieds (Craigslist, Kijiji) or visit dealerships specializing in classic cars and trucks.
- Auctions: Live and online auto auctions (Mecum, Barrett-Jackson) often feature high-quality examples, but be prepared for competitive bidding and buyer’s premiums.
- Car Shows & Swap Meets: Attending local and regional classic car shows and swap meets is a great way to see trucks in person and connect with owners.
Tips for a Successful Purchase
- Set a Realistic Budget: Factor in not just the purchase price, but also potential repairs, registration, insurance, and any planned modifications.
- Thorough Inspection: Never buy sight unseen. If you can’t inspect it yourself, hire a trusted mechanic or appraiser in the area to conduct a pre-purchase inspection.
- Test Drive: Listen for unusual noises, check braking, steering, and transmission shifts. Test all accessories.
- Verify VIN: Ensure the VIN on the title matches the VIN plate on the truck (usually on the driver’s side door jamb or dashboard).
- Negotiate: Most classic vehicle prices are negotiable. Do your research on comparable sales to inform your offer.
- Insurance: Look into classic car insurance providers, as they often offer better rates and specialized coverage for vintage vehicles.
Potential Challenges and Solutions
- Parts Availability: Generally, parts for these Chevy trucks are widely available through aftermarket suppliers, reproduction companies, and salvage yards. However, specific trim pieces or unique options can be challenging to source.
- Solution: Join online forums and owner groups; they are invaluable resources for finding rare parts and getting advice.
- Rust Repair: This is often the most significant and costly challenge.
- Solution: Unless you’re skilled in welding and bodywork, budget for professional rust repair. Consider buying a truck from a drier climate to minimize this issue.
- Fuel Economy: These older trucks are not known for their fuel efficiency.
- Solution: Consider an engine swap to a modern, more efficient engine (like an LS-series V8) if fuel economy is a major concern and you’re planning a significant build.
- Modernizing: Older trucks lack modern conveniences.
- Solution: Many aftermarket kits are available to add power steering, power disc brakes, air conditioning, modern audio, and updated suspension components, significantly improving drivability.

Q: What’s the main difference between a C-series and a K-series truck?
A: C-series trucks are 2-wheel drive (2WD), while K-series trucks are 4-wheel drive (4WD). The "C" stands for conventional (2WD) and "K" for 4×4.
Q: Which years are most desirable within this range?
A: The 1970-1972 Action Line C10 short bed and K5 Blazer models are often considered the most desirable and command the highest prices due to their classic styling and hot-rod appeal. However, the early 1973-1975 Square Bodies are rapidly gaining popularity and value.
Q: Can these trucks be daily driven?
A: Absolutely! Many 1970-1975 Chevy trucks are used as daily drivers. However, they may require more frequent maintenance than a modern vehicle. Upgrades like power steering, disc brakes, and air conditioning can significantly enhance daily drivability.
