Construction & Design:

The Fabtech 4.0 Coilover Conversion Kit is built with premium materials and precision engineering to ensure reliability and performance. The coilover bodies are crafted from stainless steel, offering excellent resistance to corrosion and wear in harsh environments. The remote reservoirs are machined from billet aluminum, enhancing heat dissipation and shock performance during extended off-road use.

Structural reinforcements include gussets on the factory upper coil buckets and cross supports on the lower mounts, which weld securely to the axle housing. This design maintains the integrity of the suspension under extreme loads and improves overall chassis rigidity. The kit’s components are engineered to integrate seamlessly with Fabtech’s Radius Arm and 4 Link Suspension systems, preserving factory geometry while enabling significant suspension travel.

Installation & Fitment:

Installation of the Fabtech 4.0 Coilover Conversion Kit is a professional-level upgrade requiring welding and drilling of approximately 10 holes. The process typically takes 4 to 5 hours and must be performed after the Fabtech Radius Arm or 4 Link Suspension system is installed. Minor trimming of the fender or wheel well area may be necessary to accommodate larger tires and wheels.

This kit fits a wide range of Ram 2500 and 3500 models from 2013 to 2018, including trims such as Big Horn, Laramie, Laramie Limited, Laramie Longhorn, Limited, Lone Star, Outdoorsman, Power Wagon, SLT, and Tradesman. It supports 4WD configurations and is optimized for tire sizes up to 38x13.50R22 with wheels up to 22x10 inches and 5-inch backspacing.

What's Included:

• Upper coil bucket support gussets
• Lower axle housing mounts with cross support gussets
• Hardware kit for welding and installation
