K30152DL

Overview:

The Fabtech 6-inch Performance Suspension System with DSS Shocks is engineered specifically for 2003 to 2005 Dodge Ram 2500 and Ram 3500 4WD diesel trucks equipped with automatic transmissions. Designed to enhance both on-road comfort and off-road capability, this suspension system provides a balanced lift that improves ground clearance and suspension travel without compromising ride quality. Ideal for truck owners seeking a durable, high-performance upgrade that maintains proper suspension geometry while accommodating larger tires up to 37x12.50R17.

This system is tailored for non-dually models and requires minor trimming for fitment with 17x9 wheels with a 5-inch backspacing. It does not fit standard cab models, ensuring compatibility with extended and crew cab configurations.

Key Features:

Fabtech’s Performance Suspension System combines advanced components to deliver superior handling, durability, and ride quality:

• Extended length 1.75" outer diameter heavy wall control arm links with urethane bushings for precise suspension geometry and increased travel
• Front lift achieved through replacement coil springs engineered for a smooth highway ride and capable off-road performance
• Multiple shock system featuring front 2.5" Dirt Logic stainless steel coilover shocks and rear 2.25" Dirt Logic stainless steel shocks for enhanced dampening
• Includes Trac Bar bracketry and a heavy-duty Pitman arm to maintain steering accuracy and control
• Upgraded end links and bump stops to support suspension articulation and prevent damage under extreme conditions
• Rear lift provided by a block and U-bolt system for reliable and stable height increase
• Transmission mount included to accommodate drivetrain alignment with lifted suspension
• Designed for 4WD diesel models with automatic transmissions only

Construction & Design:

Fabtech’s suspension system is built with durability and performance in mind. The heavy wall control arm links are constructed from robust materials and pivot on urethane bushings, which resist wear and provide consistent articulation. The coil springs are engineered to balance ride comfort and off-road capability, ensuring the truck remains stable and responsive across varied terrain.

The Dirt Logic shocks feature stainless steel bodies for corrosion resistance and longevity, while their coilover design in the front enhances suspension travel and dampening control. The rear shocks complement this setup with a slightly smaller diameter but equal quality construction. All components are precision-engineered to integrate seamlessly with the factory mounting points and maintain proper suspension geometry.

Installation & Fitment:

Installation of the Fabtech 6-inch Performance Suspension System requires moderate mechanical skill and standard tools. The system is designed for direct bolt-on fitment to 2003–2005 Dodge Ram 2500 and 3500 4WD diesel trucks with automatic transmissions, excluding standard cab and dually models. Minor trimming is necessary when using 17x9 wheels with 5-inch backspacing to ensure proper clearance.

The kit includes all necessary brackets, hardware, and components to complete the lift, including a transmission mount and upgraded steering components to maintain factory drivability and alignment. Professional installation is recommended to ensure optimal performance and safety.
