Whether you call it Overlanding or Camping, adding weight to a Jeep can cause unforeseen handling and setup issues. With thousands of miles spent in the backcountry the JKS team has developed the J-Lander system with the overlanders in mind. These systems offer strength and reliability with simplicity and adjustability to cater to what the Jeep overlanding crowd needs. Built off the base J-Venture systems these kits offer on-road comfort along with off-road capability ready to hit the trail while upgrading a few key components. HD dual rate coil springs are used 3.5” up front with the rear receiving 2.5” springs in addition to ACOS spacers to dial in the ride height based on how heavy your Jeep is loaded. Specially designed FOX 2.0 IFP shocks are added for improved damper performance along with front and rear J-Link lower control arms, an adjustable track bar, quicker disconnects and more all designed to great ride and performance when you get off the grid.
