Adventure-X2 is Rock Krawler's long-arm answer for the Gladiator owner who wants a daily driver that can also take a beating on the trail. It pairs a high clearance 4-link front suspension with an independent high clearance 3-link rear, and every control arm has the service-free Adventure Series joint. This is a weld-in system for Sport, Overland and Mojave trims, gas or diesel.

Why this system
- High clearance 4-link front and independent 3-link rear long-arm geometry.
- Adventure Series joints in every control arm isolate road vibration about like an OE bushing, offer high misalignment and never need grease.
- X2 rear geometry has enhanced rear instant center and roll center, and Rock Krawler calls it the smoothest riding 3-link you can take down a trail.
- The X2 axle bracket system gains 4.5 inches of rear clearance, and the rear anti-squat is adjustable.
- Heat shield thermal barrier products protect the front control arm joints at the frame, like the factory setup.
- Built as a compromise between highway handling and hard-core off-road ability.
Pick your package
Pick gas or diesel first, since the diesel kit is built specifically for the 3.0L Eco-Diesel. Then choose how you want to handle shocks.
- Base System (No Shocks). The full kit minus shocks, for anyone who already has a shock setup picked out. Bump stops ship with every shock package, so here they are a separate buy (Rock Krawler part RK07464). Rock Krawler's generic shock lengths: front 17.5 inches collapsed and 29.5 extended, rear 17 collapsed and 28 extended.
- Bilstein 5100 Shocks. Rock Krawler pairs these with its multi-rate coils. Maintenance free, bump stops included.
- Stage 1 (RRD 2.25 IFP Shocks). Rock Krawler's own RRD 2.25 inch IFP shocks, built in-house: hard anodized fluted aluminum body, 3/4 inch 17-4 PH stainless shaft, billet aluminum valving and dual DU shaft bearings. Serviceable, rebuildable and revalveable. Bump stops included.
- Comp System. Coilovers up front, coil springs still in the rear. It uses 2 5/8 inch RRD racing coilovers with remote reservoirs in the front and matching 2 5/8 inch RRD shocks with remote reservoirs in the rear, good for 13.3 inches of front axle travel and 13.1 inches of rear axle travel. Rock Krawler points this one at people who still carry small loads or tow small trailers.
- Comp System with Fast CD Adjusters. Same layout as the Comp System, with Fast CD (compression dampening) adjusters on the front coilovers and rear shocks for more tuning.
- Trail Runner System. Coilovers at all four corners, with 13.3 inches of front axle travel and 13.75 inches in the rear. Rock Krawler notes rear coilovers do not handle changing loads well, so towing or hauling a lot of weight in the bed is not ideal.
- Trail Runner System with Fast CD Adjusters. The Trail Runner layout with Fast CD (compression dampening) adjusters added to the coilovers.
Coilover packages need some fabrication. Rock Krawler lists removing the factory shock mount on the frame, removing the factory shock and spring mount on the axle, and welding the new coilover mount to the axle.
Fitment and what else you will need
- Fits the 2020+ Jeep Gladiator JT, 4-door, 4WD, Sport, Overland and Mojave trim. Engine: gas (3.6L Pentastar V6) and diesel (3.0L Eco-Diesel).
- Lift heights are based on a Rubicon with a standard build (front bumper and winch, rear bumper and full-size spare). With a spare delete, drop 1 inch of rear coil lift height; with a heavily up-fitted or overland-style rear, go up 1 inch.
- Wheels and tires: on Sport and Overland, 3.5 inches of backspacing, with 37 inch tires under full fenders or 38 inch with trimmed or high-lined fenders. On Mojave, 4.5 inches of backspacing for 37 inch tires and 3.5 inches for 40 inch tires (37 or 38 inch under full fenders, 40 inch trimmed). A 3 inch bump stop height is recommended.
- Rock Krawler recommends a new front driveshaft if you plan to off-road routinely (it names Adam's Driveshaft, Tom Woods and J.E. Reel).
- This is a weld-in kit. Rock Krawler lists welding of the front and rear long-arm frame-side mounts, removal of the factory frame-side lower front control arm mounts, removal of the factory frame-side front and rear upper control arm mounts and removal of the axle-side track bar mount.
- Rock Krawler recommends limiting straps to avoid over-extending suspension components after the vehicle is set up.
- An optional Pro-X cradle is available for Dynatrac XD60 rear axles (RK08078) and Ultimate Dana 60 rear axles (RK08068).
Rock Krawler lists lifetime warranty coverage on this system, and lead times of about 3 to 4 weeks on long-arm kits, counted in business days from the order date.
