Fabtech 2018 Jeep JL 4WD 4-Door 3in Long Arm Crawler Box Kit

If you're looking to take your 2018-2023 Jeep Wrangler off-road for serious crawling, this Fabtech 3-inch Long Arm Crawler Box Kit is designed to handle it. This kit focuses on improving your Jeep's suspension geometry and strength for demanding trails, offering a well-built system that works right out of the box without needing constant adjustments or fabrication.

The key to this kit's performance is its long arm design. The front link arms mount to a full-width crossmember that bolts directly to the frame rails, not only setting the correct geometry for superior handling through the suspension's travel but also adding strength to the JL's frame for hard off-road use. The rear links attach to new frame mounts that are positioned for better ground clearance and approach angles. Fabtech uses massive lower link arms, constructed from 2-inch diameter, .313-inch wall tubing, which are built to resist bending. These arms are equipped with Fabtech's 5 Ton joints, known for their smooth and quiet operation on the street and their durability off-road.

This kit includes front and rear dual-rate coil springs, front and rear Stealth Monotube shocks, front and rear bump stop extensions, track bar brackets, brake line drops, sway bar links, and heavy-duty flipped draglink. It's designed to work with Fabtech's 3-inch lift crawler systems (PN K4135DL/K4136DL).
