This Fabtech K4144DL / K4145DL 5 inch Crawler lift kit for the Jeep Wrangler JL is an awesome suspension upgrade for those serious about their off-roading.  This long arm lift kit will increase suspension articulation while improving suspension performance and durability.

A key part of the mounting of the Crawler’s 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" OD .313 thick wall tubing that is guaranteed not to bend. Upper and lower Link Arms includes the Fabtech’s 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.
