The Rock Krawler JK 4.5 Adventure-X Stretch Systems is the ultimate in compromise between daily driver/hard core off-roader. The Adventure-X systems combine the benefits of a full high clearance 4 link front suspension with a high clearance independent 3 link rear suspension. This is where conventional on road handling meets bad ass off-road ability. The rear system uses our tried and true independent 3 link conversion with X2 rear suspension geometry with enhanced rear instant center(s) and rear roll center(s). The new high clearance axle mounts provide 3.5” of ground clearance under the rear axle as compared to stock. The rear upper shock relocation brackets ensure you do not lose any shock or suspension travel. The combination of a full high clearance 4 link long arm front suspension and high clearance independent 3 link rear long arm suspension lets you dominate the streets and the trails.

*hardware and detailed instructions
Notes:
*The X Factor Stretch System is designed for flat fender and stretch rear corner use. This will require body work.
*Requires removal of the OEM frame side front and rear lower control arm mounts.
*Requires removal of the OEM frame side front and rear upper control arm mounts.
*Requires welding of the front and rear frame side long arm mounts.
*Minor exhaust rerouting required before the collector on the driver's side. This is recommended to be done prior to the suspension system being installed.
*Requires removal of the OEM rear axle side brackets.
*Requires welding of the provided rear axle side control arm/shock/sway bar link bracket, track bar bracket and rear axle truss.
*Requires removal of the OEM frame side rear shock mount.
*Requires welding of the provided frame side rear shock mount.
*Rear shocks will require a standard bushing and sleeve just like the rear lower shock bushing and sleeve. We have removed the weakness of the bar pin setup with the supplied rear upper shock mounts.
*Recommend installing limiting straps to avoid over extension of suspension components after vehicle is all set up.
*This 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.
*The rear upper third link is designed around standard low pinion rear axles. When ordering for high pinion rear axles please contact us directly so we can ensure proper fitment as best as possible.
*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.
