Eaton Truetrac Limited Slip Differential

2011–2018 Ram 1500/2500/3500 3.0L-6.7L Engines

Part #: 917A730

Overview

The Eaton Detroit Truetrac is a premium helical-gear style limited-slip differential designed to maximize traction and improve vehicle handling under a variety of driving conditions. Unlike traditional clutch-type limited-slip differentials, the Truetrac operates smoothly and automatically without the need for maintenance or manual adjustments. This makes it an excellent upgrade for Ram 1500, 2500, and 3500 models equipped with engines ranging from the 3.0L EcoDiesel to the 6.7L Cummins diesel, as well as the 5.7L Hemi and 6.4L 392 HEMI V8s.

Ideal for drivers seeking enhanced traction on-road and off-road, the Truetrac ensures power is efficiently distributed to the wheels with the most grip, reducing wheel spin and improving control in slippery or uneven terrain. Its robust design and reliable performance make it a trusted choice for both daily driving and demanding work environments.

Key Features

The Eaton Detroit Truetrac offers advanced technology and durable construction to deliver superior traction and reliability:

• Effective in both forward and reverse driving conditions for consistent traction
• Improves vehicle stability and cornering by balancing power between wheels
• Compatible with a wide range of Ram trucks from 2011 to 2018 with various engine options
• Enhances off-road capability and on-road handling without sacrificing drivability
• Durable construction engineered to withstand heavy-duty use and high torque loads
• Direct replacement for factory limited-slip or open differentials

Construction & Design

The Truetrac differential features a precision-engineered helical gear set that replaces traditional clutch packs with a robust, gear-driven mechanism. This design eliminates the common wear points found in clutch-type limited-slip differentials, resulting in a longer service life and consistent performance. Manufactured by Eaton, a leader in drivetrain technology, the Truetrac is built from high-strength alloy steel components that are heat-treated for durability and resistance to wear under demanding conditions.

Its compact design fits directly into the factory differential housing, ensuring a seamless upgrade without the need for extensive modifications. The internal gears mesh smoothly to provide progressive torque transfer, allowing the differential to respond instantly to changes in traction without binding or chatter.

Installation & Fitment

The Eaton Detroit Truetrac is designed as a direct bolt-in replacement for the 9.25-inch differential in Ram 1500, 2500, and 3500 trucks from model years 2011 through 2018. It fits vehicles equipped with the following engines: 3.0L EcoDiesel, 3.6L V6, 5.7L Hemi, 6.4L 392 HEMI, and 6.7L Cummins diesel. Installation requires standard differential service procedures and should be performed by a qualified technician to ensure proper setup and preload settings.

No special maintenance is required after installation, allowing owners to enjoy improved traction and handling without added upkeep.
