Adventure X PRO takes the standard Adventure X mid-arm kit and adds a triangulated rear. Bolt-in upper control arms triangulate the rear axle so it stays centered without leaning on a track bar, which Rock Krawler says calms the rear suspension bind and smooths out the highway ride. This 4.5 inch version is for Sport, Overland and Mojave Gladiators, and everything about it is bolt-in, with welding optional on the rear cradle.
What's in the kit
- 4 coil springs (triple-rate front, quad-rate rear)
- 2 front adjustable high clearance lower control arms
- 2 front adjustable upper control arms
- 2 front spring pads
- 1 adjustable front track bar
- 2 Gen-II front sway bar links
- 2 rear adjustable high clearance lower control arms
- 2 rear adjustable upper control arms
- 2 rear spring pads
- 2 adjustable rear sway bar links
- 1 bolt-on rear track bar relocation bracket
- 1 rear bolt-on Pro-X cradle (welding optional)
- 2 rear triangulated upper arms
Shocks depend on the package you pick. Bump stops come with every shock option. Coilover packages add the shock towers and brackets they need.
Why this system
- Rear bolt-in triangulated upper control arms keep the axle centered, allow removal of the rear track bar and cut the crosstalk between front and rear track bars
- Eight adjustable arms with maintenance-free Adventure Series joints and 70 degrees of total misalignment
- Bolt-on Pro-X rear cradle, with welding optional
- Caster and pinion angle are adjustable at both axles
- Triple-rate front and quad-rate rear coils plus correction pads for the factory spring bow
- Gen-II front sway bar links for quick axle freedom off-road
Pick your package
- Base System (No Shocks): everything except shocks. Handy if you already own a shock package you like. Bump stops are included with the shock options only and can be bought on their own as RK07464.
- Bilstein 5100 Shocks: Bilstein 5100 shocks, maintenance free and matched by Rock Krawler to its multi-rate springs. Bump stops are in the box.
- Stage 1 (RRD 2.25 IFP Shocks): RRD 2.25 inch IFP shocks from Rock Krawler, built in house with a fluted hard anodized aluminum body that cools like a 2.5 inch shock, a 3/4 inch 17-4 PH stainless hard chrome shaft, billet valve components and dual DU bearings. Serviceable, rebuildable, revalveable. Bump stops included.
- Comp System Stage 1: a front coilover and rear coil spring combination. You get 2.625 inch RRD remote reservoir coilovers (13 inches of travel, 14.44 inches of front axle travel) and matching 2.625 inch RRD remote reservoir rear shocks (12 inches of travel, 15 inches of rear axle travel), along with quad-rate rear coils and spring correction seats. Rock Krawler positions it for trucks that still tow small trailers or carry small loads.
- Comp System Stage 2 (Fast CD): Comp System hardware with Fast CD (compression damping) adjusters up front and in the rear, good for up to 30% more compression damping with infinite settings.
- Trail Runner Stage 1: four coilovers, 2.625 inch RRD remote reservoir units. It gives the Gladiator the most off-road ability Rock Krawler offers in this system and is tuned for the street, though Rock Krawler cautions against towing or loading the bed heavily with rear coilovers.
- Trail Runner Stage 2 (Fast CD): Trail Runner plus Fast CD adjusters on the coilovers, so you can tune compression damping.
Fitment and what else you'll need
- Fits the 2020+ Jeep Gladiator JT, 4 door, 4WD, Sport, Overland and Mojave trim levels. Engine: 3.6L Pentastar V6 (gas models)
- Rock Krawler wheel guidance: Sport and Overland, 3.5 inches of backspacing with 37/38 inch tires; Mojave, 4.5 inches with 37 inch tires or 3.5 inches with 40 inch tires
- Tire guidance (3 inch bump stop height recommended): Sport and Overland, 37 inch tall with full OEM fenders or 38 inch with trimmed or high-lined fenders; Mojave, 37/38 inch tall with full fenders or 40 inch 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)
- Welding the rear cradle is recommended for 37 inch tires and larger
- 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
- 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
