When it comes to diesel performance, few names are as respected as Cummins. Known for their legendary reliability, impressive torque, and long lifespan, Cummins diesel engines have powered a wide range of trucks across decades — from light-duty pickups to heavy-duty haulers. If you’ve ever wondered what trucks have Cummins engines, here’s a quick overview.

1. Dodge Ram and Ram Trucks

The most famous partnership in the diesel truck world is between Cummins and Ram (formerly Dodge Ram).
Since 1989, Ram has equipped its 2500 and 3500 models with Cummins diesel engines, starting with the iconic 5.9L 12-valve and later evolving to the 6.7L Cummins engine used today.

Popular Cummins-powered Ram models include:

• Dodge Ram 2500 (1989–present)

• Dodge Ram 3500 (1989–present)

• Ram 4500 & 5500 Chassis Cab trucks

These engines are praised for their exceptional towing capacity, fuel efficiency, and long-term durability.

2. Nissan Titan XD

Another notable truck featuring a Cummins powerplant is the Nissan Titan XD.
From 2016 to 2019, Nissan offered the 5.0L Cummins V8 Turbo Diesel option.
While it was eventually discontinued, this partnership brought Cummins power to a light-duty truck, giving owners a strong mix of towing power and everyday drivability.

3. Medium and Heavy-Duty Trucks

Cummins engines are also standard in many medium- and heavy-duty commercial trucks, such as:

• Freightliner

• Peterbilt

• Kenworth

• International

• Volvo Trucks

These trucks often use larger Cummins engines such as the ISX, X15, or L9, designed for maximum torque and reliability under continuous heavy loads.

4. Other Vehicles and Applications

Beyond pickups and commercial trucks, Cummins engines power:

• School buses

• Construction and agricultural equipment

• Marine engines

• Power generators

This widespread use reflects the versatility and dependability of Cummins engines across industries.

Cummins engines have earned their place as a trusted power source for both everyday trucks and heavy-duty equipment. Whether it’s a Ram 2500 or a Kenworth semi-truck, the name Cummins guarantees strength, endurance, and efficiency.
