Adventure-X means eight adjustable control arms, every one of them on Rock Krawler's service-free Adventure Series joints. Upper and lower arms both adjust, so you can set caster and pinion angle front and rear to suit the tires you are running. This is the 2.0 inch kit for Sport, Overland and High Altitude Gladiators, with Rock Krawler's high-clearance lowers, GEN-II quick disconnect front sway bar links and corrected track bar geometry.

Why this system
- Triple-rate front coils and quad-rate rear coils, tuned for the Gladiator. Rock Krawler says they ride better than the factory springs on the street, and they have the free length to stay seated and flex off-road.
- Coil spring correction seats take out the spring bow built into the factory setup and correct vehicle lean, so the Jeep sits level on all four corners.
- Track bar geometry is corrected at both axles (adjustable front track bar, bolt-on rear track bar relocation bracket), so the axles end up centered under the body and the highway handling stays honest.
- All eight control arms are adjustable and service-free, so caster and pinion angle can be tuned front and rear to match the tires and driveline you actually run.
- Gen II quick disconnect front sway bar links and adjustable rear sway bar links.
- Rock Krawler lists an improved rear roll center, and the kit is upgradable to its long arm system later.
- Lifetime warranty coverage, as listed by Rock Krawler.
Pick your package
- Gas or Diesel. Rock Krawler lists separate part numbers for the gas Gladiator and the diesel Gladiator (diesel part numbers carry a D, like JT20AXM-D), so pick the one that matches your engine.
- Base System (No Shocks). The kit as listed above with no shocks, for the builder who already has shocks picked out. Bump stops are sold separately (Rock Krawler part RK07464).
- Bilstein 5100 Shocks. The kit plus a set of Bilstein 5100 shocks. Rock Krawler calls them maintenance free and a great pairing with its multi-rate coil springs. Rock Krawler's Bilstein package number for the 2.0 and 3.0 inch lifts is RRD04058-B51.
- Stage 1 (RRD 2.25 IFP Shocks). Rock Krawler's in-house shock: a 2.25 inch O.D. military grade hard anodized fluted aluminum body with the cooling surface area of a 2.5 inch shock, a 3/4 inch 17-4 PH stainless steel hard chrome plated and polished shaft, a billet aluminum valve circuit, dual DU shaft bearings and double redundant sealing. Serviceable, rebuildable and revalveable.
Fitment and what else you'll need
Fits the 2020 and newer Jeep Gladiator JT (4-door) in Sport, Overland, High Altitude and Mojave trims. Gas part numbers are for the 3.6L Pentastar V6 gas Gladiator; diesel part numbers are for the 3.0L EcoDiesel.
Rock Krawler bases its lift heights on Rubicon models in a standard build (front bumper and winch, rear bumper and full-size spare). If you delete the spare, drop 1 inch of rear coil lift height; for an overland style or heavily up-fitted rear end, go up 1 inch.
