- 2007 to 2016 JK Wrangler Unlimited and Rubicon Unlimited (4 door models)

The Rock Krawler 1.5in X Factor System was designed for Jeep Wrangler JK owners who want to run flat fenders and get the absolute most out of their low COG build. The 1.5in triple rate coils provide an unbelievable ride and tons of suspension travel. The high clearance adjustable lower control arms are more robust than stock arms and are less likely to get you hung up on the trails. The adjustable front and rear uppers combine with the lowers to allow for almost unlimited suspension travel and adjustability beyond belief. The sway bar disconnects allow you to open up the off-road ability of your JK when disconnected. The front and rear stainless steel brake lines firm up the brake pedal to help control larger wheels and tires. The rear axle is pushed back 1in so it is properly centered under most standard Flat Fenders. Enjoy the street and the trails with the Rock Krawler 1.5in X Factor System.

CHOOSING SHOCKS
If choosing a brand of shock that we have not provided a part number for, match
your shock choice as closely as possible to the generic length recommendations
below.

(We can not ensure that the valving profile in your shock choice will pair well with
our kits. This is why we recommend using our RRD Racing shocks or the provided
Bilstein part numbers)

Generic Front Shock
Recommendation with 2in bump stops - 15in Collapsed to 26in Extended

Generic Rear Shock
Recommendation with 2 in bump stops - 15in Collapsed to 25in Extended

NOTES!
- Welding of the offset rear coil spring mounts is required.
- We typically recommend 4.5in of back spacing on rims for 33in and 35in tall tires.
- We typically recommend 3.5in of back spacing on rims for 37in tall tires.
- For 2012 and newer models an aftermarket front driveshaft with 2in O.D. steel tubing is recommended, but not required.
- The X Factor System allows the rear axle to be pushed back up to 1in 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.
