Powertrain & Performance

2025 RAM Heavy Duty

The 2025 RAM 2500/3500 HD lineup offers robust engine choices aimed at both daily duty and heavy‑haul challenges:

• 6.4 L HEMI V8 gasoline — strong base gas power

• 6.7 L Cummins Turbo‑Diesel I6 — available with Best‑in‑Class diesel torque around 1,075 lb‑ft on some configs for great pulling strength.

• New TorqueFlite® HD eight‑speed automatic brings smooth shifts on heavy loads.

RAM’s high‑output Cummins is legendary for heavy towing and sustained load work, giving drivers confidence under long hauls or rugged job site conditions.

2026 Chevrolet Silverado Heavy Duty

Chevrolet equips the 2500HD and 3500HD with a lineup engineered for power right from the factory:

• 6.6 L V8 gasoline — reliable base HD performance

• 6.6 L Duramax Turbo‑Diesel V8 — known for strong torque and heavy‑duty performance

• Silverado HD engines are claimed to deliver more standard torque and horsepower vs RAM HD, giving drivers plenty of grunt when loaded.

Add in a 10‑speed automatic transmission and Silverado HD’s carrying capability becomes even more usable in real‑world hauling conditions.

Towing & Payload: Workhorse Numbers

Heavy‑duty trucks are all about capability, and this is where both truly earn their keep:

Towing

• RAM 2500/3500 HD — With the Cummins diesel, towing figures can reach around 20,000 lb configurations.

• Silverado 2500/3500 HD — Max diesel towing can surpass RAM’s numbers (e.g., over 22,000 lb on some models), especially in crew cab setups.

This means if your priority is the absolute highest towing capacity — like pulling large fifth‑wheels, horse trailers, or commercial gear — Silverado HD tends to hold the edge when fully equipped.

Payload

• RAM HD — Offers significant payload figures often stronger than competitors in gas setups and competitive with diesel models.

• Silverado HD — Very capable in its own right, but depending on configuration may trail slightly behind RAM’s peak payload numbers.

Bottom line: Silverado HD often wins the max towing battle, while RAM HD can excel in payload and torque per pound thanks to its Cummins diesel.
