Construction & Design

Skyjacker’s coil system is built with durability and performance in mind. The coil springs utilize proprietary Softride® technology, which enhances spring longevity and ride quality by optimizing the coil’s internal structure. The kit’s brackets and hardware are crafted from heavy-duty steel, engineered to withstand the high stresses of lifted suspension systems and off-road use.

The included ADX 2.0 shocks feature a remote reservoir design with an Internal Floating Piston (IFP) that separates nitrogen gas from the oil, preventing cavitation and foaming. This technology ensures rapid shock response across a wide range of speeds and terrain conditions, delivering consistent damping performance whether you’re cruising on the highway or navigating rough trails.

Installation & Fitment

This coil system is engineered specifically for the 2018 Ram 3500 with the 6.7L diesel engine, ensuring a precise fit and maintaining factory suspension geometry. Installation involves replacing the front coil springs and shocks, along with mounting the supplied brackets and hardware to maintain proper alignment and driveline angles. The rear lift is achieved with a 5-inch block and U-bolt kit, complemented by a driveshaft spacer to correct driveline positioning.

Professional installation is recommended to ensure all components are properly aligned and torqued to factory specifications, preserving vehicle safety and performance.
