Overview
The Rubicon Express RE7142FP is a standard coil lift kit for the Jeep Wrangler JK, supplied with front and rear Fox Performance shocks. Rubicon Express built its FOX-shock kit numbers for buyers who want that shock brand on a complete Rubicon Express system, and this one uses the standard coil spring setup rather than the super-flex arms.
The kit has a lift height range of 3 to 4.99 inches, with replacement coil springs at both ends. Cam bolts let you set caster and pinion angle after installation, and the front track bar, rear track bar bracket and sway bar end links are upgraded in the same kit.
The FOX Performance Series shocks are covered by the FOX warranty and are not eligible for the Rubicon Express Advantage Warranty. Keep that difference in mind when you register the kit.

Choosing a lift height
A coil spring lift raises the body by changing the spring and shock setup at each corner, so the rest of the drivetrain and steering see new angles. Replacing the shocks at the same time keeps damping matched to the new ride height. When choosing how far to lift, consider the tires you plan to run, the bumpers and winch you carry, and how much daily road use the vehicle gets, since larger tires and heavy gear change the load on the springs.
After installation, the track bar, sway bar end links and bump stops take up the loads the lift changes. Recheck the bolts on these parts after the first few trail runs, and look for worn bushings or cracked bump stops at each service. Caster and pinion angles should be checked with an alignment once the cam bolts are set.
