Fabtechs JL Crawler long arm systems are built to meet the most experienced drivers expectations without having a questionably fabricated suspension. If you are in the market for a system that will work properly right out of the box and does not require continued fabrication and constant maintenance, look no further. A key part of the mounting of the Crawlers 5 Ton Link Arms to the frame is the geometry and ground clearance. The location of the frame side of the link arms is critical in providing superior handling throughout the travel range. Fabtech has found the sweet spot geometry for the link arms that provide a superior driving long arm system compared to all others on the market. Front link arm are mounted to a full width crossmember that spans frame rail to frame rail. This crossmember is a key in not only in mounting the Links arms at the correct geometry but it adds critical strength to the lighter weight JL frame for hard offroad use. Rear links attach to new frame mounts on the side of the frame for increased ground clearance and approach angle. The Fabtech lower Link Arms are massive and built of 2 in. OD .313 thick wall tubing that is guaranteed not to bend. Upper and lower Link Arms includes the Fabtechs legendary 5 Ton joints that come with lifetime guarantee of never wearing out. They are superior for offroad use with a smooth quiet operation on the street.

The Sport system features American made coil springs that are a Dual Rate design allowing for long travel suspension use offroad with a smooth highway ride. The first stage of the spring provides a soft ride with the ability to extend for additional travel. The second stage is designed to handle the payload of the vehicle and address large impact absorption at higher speeds. The Dual Rate coil springs are corner specific to the JL. This keeps the vehicle level side to side while allowing for increased suspension travel. Four bump stops extensions utilize the factory bump stops for compliant cushioning at full compression. The extensions retain the stock down travel to eliminate over cycling of the suspension and driveline. The extended length front and rear sway bar links with urethane bushings reposition the bars to work within the factory operating planes. By extending the length of the links, it prevents the sway bar from going over center and creating bind at full extension travel. A heavy duty rear track bar bracket re-centers the axle while retaining the factory roll center of the vehicle with the increased ride height.
