Overview

The Fabtech 5" Dirt Logic 2.5 Resi Coilover Kit is a premium suspension upgrade engineered specifically for 2018 to 2020 Jeep Wrangler Unlimited JL models equipped with the 3.6L V6 engine. This front coilover conversion replaces the factory separate coil spring and shock assembly with a high-performance Dirt Logic 2.5 coilover system, delivering enhanced off-road capability and improved on-road comfort. Designed for Jeep enthusiasts who demand superior wheel travel and refined handling on rugged terrain without sacrificing daily drivability, this kit offers a balanced suspension solution that excels both on and off the trail.

Construction & Design

The Fabtech Dirt Logic coilovers are built to withstand the rigors of off-road driving while maintaining reliable performance on pavement. The shock bodies are crafted from stainless steel, providing excellent resistance to rust and corrosion even in harsh environments. Billet aluminum remote reservoirs not only add structural strength but also enhance heat dissipation, ensuring consistent damping performance during prolonged trail use.

All aluminum components are polished and anodized, offering both an attractive appearance and protection against environmental wear. The coilover design integrates seamlessly with the Jeep’s factory coil spring bucket, preserving the vehicle’s original suspension geometry and structural integrity for a secure and reliable fit.
