The Rock Krawler Suspension JK Wrangler 3.5 inch Adventure - X Long-Arm 6 INCH STRETCH System 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). We provide the necessary brackets and control arms needed to achieve a 6" rear suspension stretch in order to give an enhanced wheelbase. This helps with greater off-road capability and better on-road handling characteristics in a 2-door wrangler. 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.

When we design a system, our goal is to provide you with the most comprehensive solution and the best geometry, install exceptional value, and be the foundation for every adventure whether it be on the Street, In tow, or down a Trail!  Thank you for considering Rock Krawler Suspension

Wheel Fitment:
  • We typically recommend 4.5" of backspacing on a wheel used with 33" & 35" tall tires

Tire Fitment:

  • 33" or 35" Tires using OEM fender flares
  • 37" tires if using flat fenders
 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 up-fitted build in the back, we recommend upsizing 1” in coil lift height for the rear.
  • We recommend a new front driveshaft if you plan to off-road routinely.(Adam's Drivesahft,Tom Woods,J.E. Reel)
  • The Adventure - X 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 frame side rear shock mount.
  • Requires welding of the provided frame side rear shock mount.

  • Recommend installing limiting straps to avoid over extension of suspension components after vehicle is all set up.
  • 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.
