Overview:

The Fabtech 4.0 Coilover Reservoir Dirt Logic Suspension (DLSS) Conversion Kit is engineered to upgrade the front suspension of Ram 2500 and 3500 trucks, enabling the installation of the massive Dirt Logic 4.0 Resi Coilovers. Designed specifically for Ram 2500 models from 2014 to 2020 and Ram 3500 models from 2013 to 2018, this conversion kit transforms your factory suspension into a high-performance setup that excels both on and off the road.

This system is ideal for enthusiasts seeking superior ride quality, enhanced off-road capability, and increased suspension travel. It is a premium upgrade that complements Fabtech’s Radius Arm and 4 Link suspension systems, delivering a smooth highway ride while maintaining exceptional damping performance over rough terrain.

Key Features:

The Fabtech 4.0 Coilover Conversion Kit offers a range of advanced features designed to maximize durability, performance, and fitment precision:

• Enables installation of Dirt Logic 4.0 Resi Coilovers with remote billet aluminum reservoirs
• Utilizes factory upper coil bucket reinforced with support gussets for enhanced strength
• Lower mounts weld directly to the axle housing with cross support gussets to maintain factory Track Bar bracket integrity
• Dirt Logic 4.0 coilovers feature stainless steel bodies for superior corrosion resistance
• Designed to accommodate tire sizes up to 37" with minor trimming required
• Compatible with 17x9, 18x9, 20x9.5, and 22x9.5 wheels with 5" backspacing
• Provides outstanding off-road damping and smooth highway ride quality
• Requires prior installation of Fabtech Radius Arm or 4 Link suspension systems

Construction & Design:

Fabtech’s conversion kit is engineered with durability and performance in mind. The upper coil bucket retains the factory mounting location but is reinforced with gussets to handle the increased loads from the larger coilovers. The lower coilover mounts are custom-fabricated to weld securely onto the axle housing, featuring cross support gussets that preserve the factory Track Bar bracket’s strength and alignment.

The Dirt Logic 4.0 coilovers themselves are constructed with stainless steel bodies to resist corrosion and extend service life in harsh environments. The remote reservoirs are machined billet aluminum, enhancing heat dissipation and maintaining consistent damping performance during extended off-road use.

Installation & Fitment:

Installation of the Fabtech 4.0 Coilover Conversion Kit is a professional-level upgrade estimated to take 4 to 5 hours. The process requires welding the lower mounts to the axle housing and drilling approximately 10 holes. Minor trimming of the wheel wells may be necessary to accommodate larger tires and wheels.
