Adventure X2 No Limits is the long-arm kit for a Rubicon that does real work in both worlds. A full high clearance 4-link front and a high clearance independent 3-link rear sit on service-free Adventure Series joints, and the "No Limits" front sway bar keeps the Rubicon's electronic disconnect in play. At 4.5 inches it is a weld-on system, built for someone ready to commit to long arms.

- X2 rear geometry with enhanced rear instant and roll centers

Pick your package
- Base System (No Shocks): the lift hardware only, no shocks. Pick this if you are supplying your own shocks. Bump stops ship with each shock option, and with no shocks they can be bought separately as RK07464.
- Bilstein 5100 Shocks: the Bilstein 5100 package, a maintenance-free option Rock Krawler says works well with its multi-rate coils. Bump stops are included.
- Stage 1 (RRD 2.25 IFP Shocks): the in-house RRD 2.25 inch IFP shock: military grade hard anodized fluted aluminum body (cooling surface of a 2.5 inch shock), a 3/4 inch 17-4 PH stainless shaft with hard chrome plating, billet aluminum valve circuit, dual DU shaft bearings and redundant sealing. They can be serviced, rebuilt and revalved. Bump stops included.
- Comp System Stage 1: front coilovers with a rear coil spring. Up front are 2.625 inch RRD remote reservoir coilovers (13 inches of travel for 14.44 inches of axle travel), paired with 2.625 inch RRD remote reservoir rear shocks (12 inches of travel for 15 inches of axle travel). A fit for trucks that still haul small loads or pull small trailers. Includes the rear quad-rate coils and spring correction seats.
- Comp System Stage 2 (Fast CD): same Comp System layout plus Fast CD adjusters on the front coilovers and rear shocks, which add up to 30% more compression damping with infinite settings.
- Trail Runner Stage 1: a coilover at every corner using 2.625 inch RRD remote reservoir coilovers. Rock Krawler says this gives the most off-road ability and a well-tuned street ride; the tradeoff is that rear coilovers do not like changing loads, so heavy bed loads and towing are not ideal.
- Trail Runner Stage 2 (Fast CD): the Trail Runner layout with Fast CD compression damping adjusters on the coilovers.
Pick Gas for the 3.6L Pentastar V6 or Diesel for the 3.0L Eco-Diesel. Rock Krawler lists the diesel as its own diesel-specific version of this kit, so choose the one that matches your engine.
Fitment and what else you'll need
- Fits the 2020+ Jeep Gladiator JT, 4 door, 4WD, Rubicon trim level. Engine: 3.6L Pentastar V6 (gas) and 3.0L Eco-Diesel (diesel option)
- Rock Krawler wheel guidance: 4.5 inches of backspacing with 37 inch tall tires, 3.5 inches with 40 inch tall tires
- Tire guidance on a Rubicon (3 inch bump stop height recommended): 37/38 inch tall with full OEM fenders, 40 inch tall with trimmed or high-lined fenders
- Lift height is figured on a Rubicon with a standard build (front bumper and winch, rear bumper, full size spare). Delete the spare and Rock Krawler suggests dropping 1 inch in rear coil lift height; load up the rear overland-style and they suggest going up 1 inch
- Rock Krawler recommends a new front driveshaft if you plan to off-road routinely (they name Adam's Driveshaft, Tom Woods and J.E. Reel)
- Running a Dynatrac XD60 or Ultimate Dana 60 rear axle? Rock Krawler offers the optional Pro-X cradle: RK08078 for the Dynatrac XD60, RK08068 for the Ultimate Dana 60
- Long arm install requires welding of the front and rear long arm frame side mounts; removal of the OEM frame side lower front control arm mounts; removal of the OEM frame side front and rear upper control arm mounts; removal of the OEM axle side track bar mount
- Coilover packages (Comp System and Trail Runner) require removal of the OEM frame shock mount and the OEM shock and spring mount on the axle, plus welding of the new coilover mount to the axle only
