Fabtech 2018 Jeep JL 4WD 4-Door 5in Long Arm Crawler Box Kit

When you're looking to take your 2018-2023 Jeep Wrangler off-road for some serious crawling, this 5-inch Long Arm Crawler Box Kit from Fabtech is designed to handle the challenge. This kit includes front and rear dual-rate coil springs, front and rear Stealth Monotube shocks, front and rear lower 5-ton link arms, front and rear bump stop extensions, front and rear track bar brackets, front and rear brake line drops, front and rear sway bar links, heavy-duty flipped draglink, and rear lower link arm mounts. It's built to provide a properly functioning suspension system right out of the box, aiming to reduce the need for constant fabrication and maintenance.

The geometry of the frame-side link arm mounting is crucial for superior handling across the entire suspension travel range. Fabtech has focused on finding the optimal geometry for these link arms, which they claim results in a superior driving experience compared to other long arm systems. The front link arms mount to a full-width crossmember that spans from frame rail to frame rail. This crossmember not only ensures the correct geometry for the link arms but also adds significant strength to the JL frame, which is beneficial for hard off-road use. The rear links attach to new frame mounts positioned on the side of the frame, which helps increase ground clearance and improve your approach angle.

The lower link arms in this kit are substantial, constructed from 2-inch outer diameter tubing with a .313-inch wall thickness, designed to resist bending. These arms, along with the upper arms, incorporate Fabtech's 5-ton joints, which are known for their smooth and quiet operation on the street while being robust for off-road conditions. This kit is intended to work with Fabtech's 5-inch lift crawler systems, specifically for part numbers K4148DL or K4149DL.
