K3139DL

Overview:

The Fabtech Basic Kit is a premium coil spring suspension system engineered specifically for 2014 to 2018 Ram 2500 trucks equipped with 2.25 Diesel Long Travel Suspension System (DLSS). Designed to improve ride quality both on and off-road, this system delivers a smoother, more controlled driving experience compared to the factory suspension. It is ideal for Ram 2500 owners who demand enhanced comfort without sacrificing the vehicle’s original load-carrying capabilities.

Fabtech’s innovative coil spring design addresses the common issue of harsh factory ride quality by utilizing a straight spring design with patent-pending angled lower mounts. This unique approach reduces stiffness and improves responsiveness over varying terrain, making it perfect for heavy-duty work trucks and off-road enthusiasts alike.

Key Features:

This suspension system combines advanced engineering with practical benefits to elevate your Ram 2500’s performance and comfort:

• Front coil springs feature a straight design with angled lower mounts for a smoother, more compliant ride.
• Rear dual-stage coil springs provide a supple ride when unloaded and firm support under heavy loads.
• Maintains factory load-carrying capacity while improving overall ride quality.
• Compatible with 37-inch tires and wheels up to 22 inches with minor trimming.
• Exclusive design not offered by other Ram suspension systems.
• Designed specifically for 4WD Ram 2500 models with diesel engines; not compatible with gas motors.
• 5-inch lift height for enhanced ground clearance and off-road capability.
• Improves vehicle handling and reduces harshness over rough terrain.

Construction & Design:

Fabtech’s coil springs are crafted from high-quality steel, engineered for durability and consistent performance under demanding conditions. The front springs utilize a straight coil design paired with patent-pending angled lower mounts, which reduces spring rate and absorbs road irregularities more effectively than the factory bowed springs. This results in a smoother ride without compromising strength.

The rear springs incorporate a dual-stage design that adapts to load conditions. When the truck is unloaded, the springs provide a comfortable, compliant ride. Under heavy loads, the second stage engages to maintain the vehicle’s factory-rated carrying capacity, ensuring stability and safety during towing or hauling.

Installation & Fitment:

The Fabtech Basic Kit is designed for straightforward installation on 2014 to 2018 Ram 2500 4WD diesel models. Minor trimming of the fender or wheel well may be required to accommodate larger 37-inch tires and wheels up to 22 inches in diameter. This kit is compatible with various Ram 2500 trims including Big Horn, Laramie, Laramie Limited (2014–2015), Laramie Longhorn, Limited (2016–2018), Lone Star (2014–2015), Outdoorsman (2014–2016), Power Wagon, SLT, and Tradesman.

Note that this suspension system is not compatible with gas-powered Ram 2500 trucks.
