Fabtech K4149DL – 18–20 Jeep JL 4-Door 5" Crawler Coilover Lift System w/ Dirt Logic 2.5 Resi Coilovers & Rear Resi Shocks

Unmatched articulation, durability, and ride quality for your Jeep JL.

The Fabtech K4149DL Crawler Long Arm System is built for Jeep enthusiasts who demand maximum off-road capability without sacrificing daily driving comfort. Engineered for the 2018–2020 Jeep Wrangler JL 4-Door, this system provides a full 5" lift, Dirt Logic 2.5 remote reservoir coilovers up front, and Dirt Logic 2.25 reservoir shocks in the rear—delivering exceptional suspension damping in even the harshest terrain.

Unlike kits that require ongoing fabrication or constant adjustment, this system is designed to perform properly right out of the box, combining race-inspired components with precision geometry for superior handling, stability, and strength.

 

Why Choose the Fabtech K4149DL for Your Jeep JL?

This is Fabtech’s flagship Crawler long arm system, designed to give Jeep JL owners the confidence to tackle extreme trails while maintaining daily drivability. With massive 5-Ton link arms, Dirt Logic coilovers, and optimized suspension geometry, it’s the ultimate suspension system for durability, articulation, and control.

Whether crawling rocks, hammering desert trails, or commuting during the week, the Fabtech K4149DL delivers a perfect balance of off-road capability and on-road comfort.
