JKS Manufacturing J-Lander 3.5in Suspension System for 18-25 Jeep Wrangler Unlimited JL 4-Door

Quadratec Part #: 16156-0760
Description
The JKS Manufacturing J-Lander 3.5in Suspension System was specifically engineered to handle the increased load and strain the is exerted on Jeep's used for overlanding. The weight of a rooftop tent and camping supplies can ruin your handling. With this in mind, JKS designed this kit for hard-hitting performance under stress. The heavy-duty dual-rate coil springs were specifically tuned for use on the 4-door Wrangler Unlimited JL, and provide a consistent ride both on and off road. With a 3.5in front and 2.5in rear lift, this kit will both lift and level your Jeep. For a level stance under any load, JKS also includes a set of their rear ACOS spacers which allow you to precisely set the rear ride height. The included FOX 2.0 IFP shocks were specifically valved to provide optimum response with the JSPEC heavy-duty springs.

Many states have laws that limit the maximum height of a lifted vehicle. Never exceed the legal height limit.
