*hardware and detailed Instructions

General Notes:

*All lift heights based on Rubicon models for standard style build (i.e., front bumper and winch, rear bumper and full-size spare).

*If building with a spare delete, we recommend dropping 1” in coil lift height for the rear.

*If building an overland or heavily upfitted build in the back, we recommend upsizing 1” in coil lift height for the rear

*We typically recommend 4.5" of back spacing on rims for 33" and 35" tall tires.

*We typically recommend 3.5" of back spacing on rims for 37" tall tires.

*For 2012 and newer models an aftermarket front driveshaft with 2" O.D. steel tubing is recommended, but not required.

*The X Factor System allows the rear axle to be pushed back up to 1" over stock which perfectly centers the rear axle assembly under typical aftermarket flat fenders. It also allows for larger tires without contacting the rock sliders or rear pinch seam.
