Diesel trucks have long been valued for their durability, towing capability, and ability to maintain strong resale value over time. Although they often cost more upfront, many buyers are willing to pay a premium for used models because engines like the Cummins and Power Stroke are known for handling high mileage when properly maintained.
Resale value depends on more than just the engine, with factors such as trim level, drivetrain, cab style, and market demand also playing important roles. Heavy-duty diesel pickups often retain their value better than many gas-powered trucks due to demand from commercial users and buyers who need serious capability. This list ranks eight current diesel trucks based on their ability to hold value in the used market.
1. Ram 3500 (High-Output Cummins)
The Ram 3500 sits at the top of the heavy-duty resale chart. It retains roughly 82.6% of its value after five years, the best figure of any heavy-duty pickup in America. Part of that comes from raw capability. Buyers see the Ram 3500 as the ceiling of what a one-ton truck can do. The High-Output Cummins is the halo engine here.
For 2026, it makes 430 horsepower, up ten horsepower from the year before. Torque is the real headline. At 1,075 lb-ft, it remains best-in-class among factory diesel pickups.
That torque arrives low, around 1,800 rpm. It makes towing near max capacity feel unhurried rather than strained. A new eight-speed TorqueFlite HD transmission replaced the old six-speed for 2026.
It’s a meaningful refinement that used buyers will notice immediately. Dual rear wheel Crew Cab models can tow up to 36,610 pounds. That number alone keeps commercial demand strong on the used market.
Specifications:
- Engine: 6.7L High-Output Cummins Turbo Diesel I6
- Horsepower: 430 hp
- Torque: 1,075 lb-ft
- Length: 231.8 inches (Crew Cab, 6’4″ box)
- Width: 79.9 inches
2. Ram 2500 (Cummins Turbo Diesel)
The Ram 2500 rides just behind its bigger sibling in resale strength. It benefits from the same Cummins reputation without the one-ton price premium.
That makes it the sweet spot for a lot of buyers. Enough capability for most towing needs, without the stiffer ride of a 3500 dually. The standard 6.7L Cummins produces solid numbers on its own. Buyers looking for maximum capability can step up to the High-Output version shared with the 3500.
Ram’s interior quality plays a real role in resale here, too. Laramie and Limited trims routinely outsell rivals on the used market because the cabin feels a class above.
Air suspension is available and genuinely desirable. It smooths out the notoriously stiff ride that heavy-duty trucks are known for. Maintenance costs are lower than those of some rivals thanks to a simpler emissions system. That matters enormously to used buyers weighing long-term ownership costs.
The 2500 also benefits from Ram’s recent reliability turnaround. J.D. Power now ranks Ram at the top of its full-size dependability study, which trickles down into stronger used demand.
Specifications:
- Engine: 6.7L Cummins Turbo Diesel I6
- Horsepower: 370 hp (standard output)
- Torque: 850 lb-ft (standard output)
- Length: 237.4 inches (Crew Cab, 6’4″ box)
- Width: 79.9 inches
3. GMC Sierra 2500HD (Duramax)
GMC’s heavy-duty diesel holds value well because it splits the difference between a work truck and a luxury vehicle. Denali trims especially command strong used prices.
The Duramax name still carries serious weight with buyers. It’s earned a reputation for durability that spans multiple engine generations. Under the hood is a 6.6L Duramax paired exclusively with the Allison 10-speed automatic.
That transmission pairing is a major selling point on the used market. Allison’s reputation for smooth, durable shifts under heavy load is almost as strong as the engine’s own reputation. Buyers actively search for the Allison badge.
GMC dresses the Sierra HD with more standard tech than the Silverado it’s based on. That includes MultiPro-style tailgates and available adaptive cruise. Denali Ultimate trims bring a genuinely upscale cabin.
That pulls in used buyers who might otherwise cross-shop a Ram Limited. Six-figure MSRPs on loaded trims mean there’s real money to lose in depreciation. Even so, the Duramax reputation keeps resale percentages competitive within the segment.
Specifications:
- Engine: 6.6L Duramax Turbo Diesel V8
- Horsepower: 470 hp
- Torque: 975 lb-ft
- Length: 250.0 inches (Crew Cab, standard box)
- Width: 82.3 inches
4. Chevrolet Silverado 2500HD (Duramax)
The Silverado 2500HD shares its bones with the Sierra, but sells to a more work-focused buyer. That’s a strength for resale, not a weakness. Fleet and ranch buyers value simplicity and proven parts availability. Chevy’s HD trucks deliver both in spades.
The Silverado HD shares the same proven mechanical foundation as the GMC, including the 6.6-liter Duramax diesel and Allison 10-speed transmission combination. Its standout features come from the practical upgrades, such as the Durabed cargo box and Multi-Flex Tailgate, which have become important selling points for used truck shoppers comparing heavy-duty models.
High Country trims bridge the gap toward luxury. But most Silverado HD resale strength comes from mid-tier work trims like LT and LTZ. Z71 and ZR2 packages add off-road credibility. That pulls in a buyer segment that Ram and Ford don’t always capture as effectively.
J.D. Power ranked the Silverado a close runner-up to Ram in its latest dependability study. That kind of validation matters when used buyers are comparing options side by side.
Specifications:
- Engine: 6.6L Duramax Turbo Diesel V8
- Horsepower: 470 hp
- Torque: 975 lb-ft
- Length: 250.0 inches (Crew Cab, standard box)
- Width: 82.3 inches

5. Ford F-250 Super Duty (Power Stroke)
The F-250 remains America’s most cross-shopped heavy-duty truck. That sheer sales volume keeps used demand consistently strong. Ford offers two diesel tunes here, which give buyers flexibility. That flexibility also helps resale, since there’s a Power Stroke for nearly every budget.
The standard 6.7L Power Stroke makes 475 horsepower and 1,050 lb-ft. Buyers wanting more can step up to the High-Output version. That High-Output engine is genuinely serious hardware. It delivers 500 horsepower and 1,200 lb-ft, numbers that lead the segment outright.
Ford’s ten-speed automatic pairs with every engine option. It’s a well-proven unit that used buyers rarely flag as a concern. Interior tech has improved significantly in recent model years.
SYNC 4 and larger touchscreens have closed the gap with Ram’s cabin advantage. F-Series brand strength alone does a lot of heavy lifting on resale. It remains the single most searched used truck nameplate in the country.
Specifications:
- Engine: 6.7L Power Stroke Turbo Diesel V8
- Horsepower: 475 hp (500 hp High-Output)
- Torque: 1,050 lb-ft (1,200 lb-ft High-Output)
- Length: 250.0 inches (Crew Cab, 6.75-foot box)
- Width: 80.0 inches
6. Ford F-350 Super Duty (Power Stroke)
The F-350 steps up capability without straying far from the F-250’s proven formula. Most of the powertrain carries over directly. Dual rear wheel configurations open up massive towing numbers. That capability draws serious commercial and RV-towing buyers into the used market.
Resale slips slightly below the F-250, mainly due to price. A loaded F-350 dually simply costs more to begin with, so the dollar depreciation looks larger even at a similar percentage. The High-Output Power Stroke is available here, too. Buyers chasing maximum towing numbers often specify it deliberately.
Single rear wheel F-350s hold value best among the trim spread. They offer nearly 3500-level capability with an easier daily driving experience. Ford’s Tremor off-road package adds genuine desirability. It’s rare among one-ton trucks and pulls in buyers who wouldn’t otherwise consider an F-350.
Payload ratings on gas-adjacent trims can actually beat the diesel in some configurations. Savvy used buyers research this carefully before choosing an engine.
Specifications:
- Engine: 6.7L Power Stroke Turbo Diesel V8
- Horsepower: 475 hp (500 hp High-Output)
- Torque: 1,050 lb-ft (1,200 lb-ft High-Output)
- Length: 266.2 inches (Crew Cab, 8-foot box, dually)
- Width: 95.9 inches (dually, mirrors included)
7. Ram 1500 EcoDiesel
The Ram 1500 EcoDiesel occupies a strange, valuable niche. Stellantis has wound down new production of the 3.0L diesel V6. That discontinuation has flipped the script on this truck. Scarcity is now driving resale prices up rather than down.
Buyers specifically seek out EcoDiesel-equipped half-tons. It remains the only widely available light-duty diesel pickup sold in the U.S. in recent years.
Fuel economy was always this engine’s selling point. Combined ratings in the high-20s made it genuinely useful as a daily driver and highway tower.
Towing capacity tops out around 12,560 pounds, depending on configuration. That’s respectable for a half-ton, even if it can’t touch heavy-duty numbers.
Used prices for clean, low-mileage EcoDiesels have held remarkably steady. Some late-model examples now command notable premiums over comparable gas-powered trims. That said, this is a half-ton, not a heavy-duty. Its resale strength is unusual and specific to diesel scarcity rather than raw capability.
Specifications:
- Engine: 3.0L EcoDiesel Turbo Diesel V6
- Horsepower: 260 hp
- Torque: 480 lb-ft
- Length: 232.9 inches (Crew Cab, 5’7″ box)
- Width: 82.1 inches
8. Ford F-450 Super Duty (Power Stroke)
The F-450 sits at the very top of Ford’s pickup lineup. It’s also the diesel truck that depreciates hardest in raw dollar terms. That’s mostly simple math. A loaded F-450 Limited can approach six figures new, and there’s more room to fall from that height.
Capability here is genuinely extreme. Properly equipped, it can tow up to 40,000 pounds and haul 8,000 pounds of payload. The diesel-only lineup keeps things simple for consumer buyers. Every retail F-450 comes with the standard or High-Output Power Stroke.
Dual rear wheels are standard across the board. That makes daily driving and parking noticeably harder than with smaller Super Duty siblings. Used buyers for this truck are a narrow, specific group. Fifth-wheel towers, horse trailer haulers, and commercial fleets make up most of the demand.
Because that buyer pool is smaller, the resale percentage lags behind the F-250 and F-350. It still holds value better than most non-diesel trucks on the market, just not as well as its own smaller siblings.
Specifications:
- Engine: 6.7L Power Stroke Turbo Diesel V8
- Horsepower: 475 hp (500 hp High-Output)
- Torque: 1,050 lb-ft (1,200 lb-ft High-Output)
- Length: 266.2 inches (Crew Cab, 8-foot box, dually)
- Width: 95.9 inches (dually, mirrors included)
