Tuff Country Long Arm Upgrade Kit

2003–2013 Dodge Ram 2500 / 3500 5.7L & 6.7L Diesel

Part #: 30942

Overview

The Tuff Country Long Arm Upgrade Kit is engineered to enhance the suspension performance of your Dodge Ram 2500 or 3500, specifically models from 2003 to 2013 equipped with 5.7L Hemi or 6.7L Diesel engines. This upgrade kit replaces the factory control arms with longer, more durable arms designed to reduce control arm angles, resulting in improved ride quality, superior handling, and increased suspension articulation. If you’re looking to lift your Dodge Ram while maintaining or improving drivability and comfort, this kit offers a refined solution that addresses common issues found in lifted trucks such as harsh ride and bump steer.

Ideal for enthusiasts who demand both off-road capability and on-road comfort, the Tuff Country Long Arm Upgrade Kit significantly reduces front suspension binding through the use of greaseable, rebuildable flex joints on both upper and lower control arms. This ensures smoother suspension movement and longer component life.

Construction & Design

The Tuff Country Long Arm Upgrade Kit is crafted from high-strength steel to provide exceptional durability and resistance to wear. Each control arm features greaseable flex joints that can be rebuilt, allowing for easy maintenance and extended service life. The design focuses on reducing the angle of the control arms, which not only improves ride comfort but also reduces stress on suspension components. This thoughtful engineering ensures that your lifted Dodge Ram maintains optimal suspension geometry, enhancing both on-road stability and off-road articulation.

Installation & Fitment

Installation of the Tuff Country Long Arm Upgrade Kit requires replacing the factory upper and lower control arms with the supplied longer arms. While professional installation is recommended to ensure proper alignment and safety, the kit is designed to fit directly onto the specified Dodge Ram models without the need for additional modifications. This upgrade is compatible with Dodge Ram 2500 and 3500 trucks from 2003 through 2013 equipped with either the 5.7L Hemi or 6.7L Diesel engines, covering multiple model years and configurations.
