2013–2018 Ram 3500 4WD

K3143

Overview:

The Fabtech Basic Kit (5in) with Performance Shocks is engineered specifically for 2013 to 2018 Ram 3500 trucks, delivering a superior ride quality over the factory suspension. Designed for drivers who demand both comfort and capability, this coil spring suspension system offers a smoother on-road experience while maintaining the heavy load capacity and ruggedness required for off-road use. Fabtech’s innovative coil spring design addresses the common stiffness found in factory setups, providing a balanced ride that adapts well to varying terrain and driving conditions.

This kit is ideal for Ram 3500 owners looking to upgrade their suspension without sacrificing the truck’s ability to handle demanding workloads or rough trails. It supports larger tires up to 37 inches with minor trimming and is compatible with a range of wheel sizes, making it a versatile choice for performance and style enhancements.

Key Features:

Fabtech’s Basic Kit with Performance Shocks incorporates advanced suspension technology and thoughtful engineering to improve your Ram 3500’s ride and handling. Key features include:

• 5-inch lift height for enhanced ground clearance and aggressive stance
• Front coil springs with a straight spring design for a smoother, more controlled ride
• Patent-pending angled lower mounts that reduce harshness and improve suspension articulation
• Performance shocks tuned to complement the coil springs for balanced damping and improved handling
• Maintains factory load-carrying capacity despite a lower spring rate for comfort
• Compatible with tire sizes up to 37/13.50R22 with minor trimming
• Supports wheel sizes ranging from 17x9 to 22x9.5 with 5-inch backspacing
• Designed exclusively for diesel-powered Ram 3500 models; not compatible with gas engines or factory air suspension

Construction & Design:

Fabtech’s suspension components are crafted from high-quality materials engineered for durability and performance. The front coil springs feature a straight design, differing from the factory bowed springs, which results in a lower spring rate and a more compliant ride without compromising strength. The patent-pending angled lower mounts optimize suspension geometry, enhancing ride smoothness and articulation over rough terrain.

Performance shocks included in the kit are precision-tuned to work harmoniously with the coil springs, providing consistent damping and improved control. Every component undergoes rigorous testing to ensure long-lasting reliability under heavy loads and off-road conditions.

Installation & Fitment:

This suspension kit is designed for straightforward installation on 2013 to 2018 Ram 3500 4WD models equipped with diesel engines. Minor trimming may be required to accommodate larger tires and wheels, particularly when running 37-inch tires with 5-inch backspacing wheels. It is important to note that this kit will not fit Ram 3500 trucks with factory air suspension or gas engines.

Installation typically requires standard suspension tools and mechanical knowledge. Professional installation is recommended to ensure proper fitment and optimal performance.

What's Included:
