Three inches of lift with adjustable upper arms in the mix. The 3.0 inch Ultimate Adventure System pairs four fixed lower arms with four fully adjustable uppers, all running Rock Krawler's service-free Adventure Series joints, so you can set caster and pinion angle for your tire size and driveline. It is the Sport, Overland and Mojave version, with corrected track bars at both axles and the triple and quad-rate coil set.

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.
- Four fixed lower arms and four fully adjustable upper arms: the uppers let you set caster and pinion angle front and rear, and the lowers stay simple.
- Gen II sway bar links up front and adjustable sway bar links in the rear.
- 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 JT30UA-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 come with every shock package; if you go with no shocks they are ordered 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 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.
