Installation NotesInstallation Difficulty:Level 3Advanced
- We typically recommend 4.5″ of back spacing on rims for 33″, 35″, and 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
Installation Time:8-10 hours Installation
