Cummins 5R110 Swap Guide

The Cummins 5R110 swap is one of the most popular ways to convert a Ford Super Duty truck from a Powerstroke engine to a Cummins while retaining the factory automatic transmission. Many builders choose to keep the 5R110 TorqShift transmission because it is strong, widely available, and already integrated into the Ford drivetrain.

Cummins to 5R110 Swap Overview

The Cummins 5R110 swap is a popular conversion for Ford Super Duty trucks originally equipped with the 6.0L or 6.4L Powerstroke engine. Many builders choose to retain the factory 5R110 TorqShift transmission because it is a strong automatic transmission that integrates well with the Ford drivetrain.

A successful Cummins to 5R110 conversion typically requires an adapter plate, flexplate, Cummins motor mounts, and supporting swap components designed for Ford Super Duty trucks.

Trucks That Use the 5R110 Transmission

The 5R110 TorqShift transmission was used in several Ford Super Duty trucks produced between 2003 and 2010.

  • 2003 Ford F-250 Super Duty
  • 2004 Ford F-250 Super Duty
  • 2005 Ford F-250 Super Duty
  • 2006 Ford F-250 Super Duty
  • 2007 Ford F-250 Super Duty
  • 2003 Ford F-350 Super Duty
  • 2004 Ford F-350 Super Duty
  • 2005 Ford F-350 Super Duty
  • 2006 Ford F-350 Super Duty
  • 2007 Ford F-350 Super Duty

Engines Originally Paired With the 5R110

  • 6.0 Powerstroke
  • 6.4 Powerstroke

Why Builders Choose the 5R110 for a Cummins Swap

The 5R110 TorqShift transmission is widely regarded as one of Ford’s stronger automatic transmissions used in Super Duty trucks.

  • Strong factory automatic transmission designed for diesel torque
  • Already installed in many Ford Super Duty trucks
  • Reliable transmission with good aftermarket support
  • Allows builders to retain the factory drivetrain layout
  • Works well with Cummins engines when paired with the correct adapter kit

For these reasons, the Cummins 5R110 swap has become one of the most common Ford diesel conversions.

Required Parts for a 12V / 24V Cummins 5R110 Swap

A typical 12V or 24V Cummins to 5R110 swap in a 2003–2007 Ford Super Duty requires several supporting components beyond the transmission adapter kit. These parts help properly mount the engine, maintain drivetrain alignment, and ensure compatibility with the factory cooling and accessory systems.

The following components are commonly used when installing a 12V or 24V Cummins engine into a Ford Super Duty equipped with the 5R110 transmission.

Installation Considerations for a Cummins 5R110 Swap

While the Cummins 5R110 swap is a popular and proven conversion for Ford Super Duty trucks, proper planning is important to ensure a smooth installation. Using the correct adapter components and swap parts helps simplify the build and ensures the Cummins engine integrates properly with the Ford drivetrain.

Several key factors should be considered during the installation process.

Cooling System Compatibility

Cooling system integration is another important consideration when installing a Cummins engine into a Ford Super Duty chassis. Proper airflow through the radiator is critical for maintaining safe engine temperatures.

Fan hub adapters and compatible fan clutches allow builders to integrate the Cummins cooling setup with the Ford radiator and maintain reliable cooling performance.

Engine and Transmission Alignment

One of the most important aspects of a successful Cummins swap is maintaining proper alignment between the engine and transmission. A precision Cummins to 5R110 adapter kit ensures the engine and transmission are positioned correctly, helping prevent drivetrain vibration and premature wear.

Correct motor mounts also play an important role by positioning the engine properly within the frame.

Cooling System Compatibility

Cooling system integration is another important consideration when installing a Cummins engine into a Ford Super Duty chassis. Proper airflow through the radiator is critical for maintaining safe engine temperatures.

Fan hub adapters and compatible fan clutches allow builders to integrate the Cummins cooling setup with the Ford radiator and maintain reliable cooling performance.

Accessory and Engine Bay Clearance

Cummins engines have different accessory layouts than the factory Powerstroke engines originally installed in Ford Super Duty trucks. During a conversion, builders must ensure adequate clearance for accessories, steering components, and cooling system components within the engine bay.

Using swap-specific brackets and mounting components simplifies installation and helps maintain proper fitment.

Cummins 5R110 Swap FAQ

Can a Cummins engine bolt directly to a 5R110 transmission?

No. A Cummins to 5R110 adapter kit is required to properly connect the Cummins engine to the Ford TorqShift transmission. The adapter kit ensures the engine and transmission are aligned correctly and allows the factory drivetrain to function properly.

What trucks use the 5R110 transmission?

The 5R110 TorqShift transmission was used in Ford Super Duty trucks from 2003 through 2010. These trucks originally came with Powerstroke engines but are commonly converted to Cummins engines while retaining the factory transmission.

Common trucks include:

• Ford F250 Super Duty
• Ford F350 Super Duty
• Ford F450 Super Duty

Is the 5R110 strong enough for a Cummins swap?

Yes. The 5R110 transmission is widely regarded as a durable automatic transmission capable of handling diesel torque. When paired with the correct Cummins adapter kit and supporting swap components, it performs well in many Cummins conversion builds.

Why do builders keep the 5R110 instead of swapping transmissions?

Many builders choose to retain the 5R110 TorqShift transmission because it is already installed in Ford Super Duty trucks and is capable of handling diesel power. Keeping the factory transmission can simplify the swap and reduce the amount of fabrication required during the conversion.

What parts are needed for a Cummins 5R110 swap?

Most swaps require several key components including:

• Cummins to 5R110 adapter kit
• Cummins motor mounts for Ford Super Duty
• Cooling fan hub adapter
• Supporting swap components for proper fitment

Using parts designed specifically for Ford Cummins conversions helps simplify installation and ensure proper drivetrain alignment.
