Suncoast Cat4 Transmission 4WD (SC-5R110CAT4-0304-4WD) for 2003-2004 Powerstroke 6.0L

Suncoast CAT4 5R110 4WD Transmission for 6.0 Power Stroke

The Suncoast CAT4 5R110 4WD transmission is a heavy-duty upgrade designed for 2003–2004 Ford trucks equipped with the 6.0L Power Stroke and 5R110 transmission. Built specifically for 4WD applications, this transmission package delivers the strength, torque capacity, and reliability needed for towing, performance builds, and demanding work conditions.

The CAT4 transmission replaces the common weak points found in the factory unit. Suncoast engineers designed this system with upgraded internal components that improve durability and holding power. As a result, the transmission can handle significantly more horsepower and torque than the stock transmission.

Built for Strength and Durability

The Suncoast CAT4 5R110 4WD transmission features upgraded clutch packs, reinforced steels, and billet internal components. These upgrades dramatically increase the transmission’s ability to handle power under load.

The stronger internal design helps prevent clutch slip and overheating during heavy towing or aggressive driving. Because of these improvements, the transmission maintains reliability even when paired with tuned or modified engines.

High-Performance Torque Converter Included

The CAT4 transmission package includes a high-performance torque converter designed to match the upgraded transmission components. This converter improves stall characteristics and delivers stronger lock-up performance.

The upgraded converter improves power transfer and helps maintain efficiency during towing or acceleration under load.

Improved Shift Quality

The Suncoast CAT4 5R110 also includes internal upgrades that improve shift firmness and timing. These improvements allow the transmission to shift faster and more consistently.

Firmer shifts help keep the engine in the optimal power band. As a result, the truck performs better during towing, heavy hauling, and performance driving.

Designed for 4WD Applications

This transmission is designed as a direct bolt-in replacement for 4WD 2003–2004 6.0L Power Stroke trucks. The system installs directly in place of the factory 5R110 transmission without modifications.

Because the package arrives as a complete assembly, installation is straightforward for professional installers or experienced technicians.
